Opis:: To improve the mechanical performance of BiTe-based thermoelectric modules, this study applies anti-diffusion layers that inhibit the generation of metal intercompounds and an electroless nickel/electrode palladium/mission gold (ENEPIG) plating layers to ensure a stable bonding interface. If a plated layer is formed only on BiTe-based thermoelectric, the diffusion of Cu in electrode substrates produces an intermetallic compound. Therefore, the ENEPIG process was applied on the Cu electrode substrate. The bonding strength highly increased from approximately 10.4 to 16.4 MPa when ENEPIG plating was conducted to the BiTe-based thermoelectric element. When ENEPIG plating was performed to both the BiTe-based thermoelectric element and the Cu electrode substrate, the bonding strength showed the highest value of approximately 17.6 MPa, suggesting that the ENEPIG process is ef-fective in ensuring a highly reliable bonding interface of the BiTe-based thermoelectric module.

Opis:: In the present study, electroless Ni–P plating was applied to Bi–Te-based thermoelectric materials as a barrier layer and the effect of the Ni–P plating on the bonding strength of the thermoelectric module was investigated. The bonding strength of the n- and p-type modules increased after being subjected to the electroless Ni–P plating treatment. In the case of the thermoelectric module that was not subjected to electroless Ni–P plating, Sn and Te were interdiffused and formed a brittle Sn–Te-based metallic compound. The shearing mostly occurred on the bonding interface where such an intermetallic compound was formed. On the other hands, it was found from the FE-EPMA analysis of the bonding interface of thermoelectric module subjected to electroless Ni-P plating that the electroless Ni-P plating acted as an anti-diffusion layer, preventing the interdiffusion of Sn and Te. Therefore, by forming such an anti-diffusion layer on the surface of the Bi–Te based thermoelectric element, the bonding strength of the thermoelectric module could be increased.

Opis:: WC-8Co cemented carbide was prepared by a high-temperature liquid phase sintering in argon at 5-200 Pa. Three microtextured grooves with a spacing of 500, 750, and 1000 μm were prepared on the surface of WC-8Co cemented carbide. TiAlCrSiN multi-element hard coating was deposited on the WC-8Co cemented carbide microtextured surface with multi-arc ion plating technology. The Vickers hardness and fracture toughness of coated and uncoated WC-8Co cemented carbide with or without a microtextured surface were investigated. The effect of different microtextured spacing on the interface bonding strength of the TiAlCrSiN coating was analyzed. The results show that with the reduction of the microtextured spacing, the Vickers hardness of the cemented carbide slightly decreases, and the fracture toughness slightly increases. The microtextured surface can improve the interface bonding strength between the coating and the substrate. The smaller the microtextured spacing, the larger the specific surface area and the higher the surface energy, so the interface bonding strength between the coating and the substrate increases.

Opis:: In this study, the effect of electroless Pd-P plating on the bonding strength of the Bi-Te thermoelectric elements was investigated. The bonding strength was approximately doubled by electroless Pd-P plating. Brittle Sn-Te intermetallic compounds were formed on the bonding interface of the thermoelectric elements without electroless Pd-P plating, and the fracture of the bond originated from these intermetallic compounds. A Pd-Sn solder reaction layer with a thickness of approximately 20 μm was formed under the Pd-P plating layer in the case of the electroless Pd-P plating, and prevented the diffusion of Bi and Te. In addition, the fracture did not occur on the bonding interface but in the thermoelectric elements for the electroless Pd-P plating because the bonding strength of the Pd-Sn reaction layer was higher than the shear strength of the thermoelectric elements.

Opis:: An artificial neural network (ANN) and an adaptive neuro-fuzzy inference system (ANFIS) are used to predict the bonding strength of different wood-based composites and veneers. The dataset used for model creation is obtained from experimental setups. The experiments involved measuring the bonding strength of wood-based composites (Flakeboard, MDF, OSB) and veneer (beech, oak, pine) using different cutting directions and adhesive types. A total of 540 experiments were conducted. The main objective of this study is to propose AI-based models (ANN and ANFIS) that could reduce the cost of experiments and computational time. The ANN model achieved correlation coefficients (R2) of 0.91 and 0.94 for training and testing, respectively. The high R² values for both training and test datasets indicate that the ANN model is well-designed. On the other hand, the ANFIS model yielded R2 values of 0.88 and 0.85 for training and testing, respectively. Based on these results, the ANN models exhibited a stronger correlation than the ANFIS models. Overall, this study demonstrates the effectiveness of using artificial intelligence models, specifically ANN and ANFIS, to predict the bonding strength of wood-based composites and veneer. By employing these models, researchers can reduce the need for extensive experimentation and save computational time, making the process more efficient and cost-effective.

Opis:: The strength of the connection between orthodontic brackets and sandblasted dental ceramics was evaluated. The strength of the bracket-ceramics connection was determined in four time intervals. Based on the obtained results, basic statistics were calculated. For the comparative analysis of average values, the following were used: ANOVA analysis of variance and Tukey’s HSD post-hoc test at the significance level of α = 0.05. The statistical analysis performed did not show any influence of the method of surface treatment (with sanding, without sanding) between orthodontic brackets and ceramics. At the same time, it has been shown that with samples storing time in aqueous environment, the quality of the connection decreases significantly, regardless of the surface treatment method used.
Zbadano wytrzymałość połączenia zamków ortodontycznych z ceramiką dentystyczną poddaną piaskowaniu. Wytrzymałość połączenia zamek-ceramika wyznaczono w czterech przedziałach czasowych. Do analizy porównawczej wartości średnich zastosowano m.in. analizę wariancji ANOVA oraz test post - hoc Tukeya HSD na poziomie istotności α = 0,05. Przeprowadzona analiza statystyczna nie wykazała wpływu metody obróbki powierzchni porcelany dentystycznej (z piaskowaniem, bez piaskowania) na jakość połączenia zamków ortodontycznych z ceramiką. Jednocześnie wykazano, że wraz z upływem czasu przechowywania próbek w środowisku wodnym, istotnie zmniejsza się jakość połączenia, niezależnie od stosowanej metody obróbki powierzchni.

Opis:: Welding is tremendously used in metal joining processes in the manufacturing process. In recent years, diffusion welding method has significantly increased the quality of a weld. Nevertheless, diffusion welding has some extent short research and application progress. Therefore, diffusion welding has a lack of relevant information, concerned with the joining of thick and thin materials with or without interlayers, on welding design such as fixture, parameters selection and integrated design. This article intends to combine innovative methods in the application of diffusion welding design. This will help to decrease trial and error or failure risks in the welding process being guided by the theory of inventive problem solving (TRIZ) design method. This article hopes to provide welding design personnel with innovative design ideas under research and for practical application.
Spawanie jest powszechnie stosowane w procesach produkcyjnych w procesie łączenia metali. W ostatnich latach metoda spawania dyfuzyjnego znacznie zwiększyła jakość spoiny. Niemniej jednak, metoda spawania dyfuzyjnego jest mało zgłębiona badawczo i krótko stosowana. Dlatego spawanie dyfuzyjne pozbawione jest istotnych informacji, związanych z łączeniem grubych i cienkich materiałów z warstwami pośrednimi lub bez ich udziału, w konstrukcji spawalniczej, takich jak mocowanie/oprawa, wybór parametrów i zintegrowana konstrukcja. Niniejszy artykuł ma na celu połączyć innowacyjne metody w zastosowaniu spawania dyfuzyjnego konstrukcji. Pomoże to zmniejszyć ryzyko prób i błędów lub niepowodzeń w procesie spawania, kierując się teorią metody rozwiązywania problemów (TRIZ). Artykuł ten ma na celu uzbrojenie personelu projektującego konstrukcje spawalnicze w innowacyjne pomysły projektowe w obszarze badań i praktycznych zastosowań.

Opis:: In the present paper, the bonding strength of Fe-based self-fluxing alloy coating deposited by plasma spraying, gluing and laser remelting and alloying on the steel substrate have been investigated. When flame melting, a globular structure is formed. Against the background of the solid solution carbide-boride phases are clearly distinguishable, between which the Fe–Fe2B and Fe–FeB eutectic colonies are situated. Laser remelting leads to the formation of metastable structures, reinforced with dendrites, consisting of alloyed Fe-α and Fe-γ. At the low laser beam speeds the coating is melted completely with the formation of a cast structure with the dendrites. When the laser beam speed is increased, the dendritic structure gets fragmented. Structures of coatings alloyed with B4C and remelted by the laser beam vary with the increase of the spot speed. The bonding strength of coating without subsequent remelting decreases by 4–5 times in comparison with remelted. The bonding strength of the reinforced glue coating has adhesive and adhesive-cohesive character. When the load increases in the coating, microcracks develop, which gradually spread to the center of the bonding surface. For plasma coatings after laser remelting without additional alloying, the maximum bonding strength is observed with the minimum laser beam speed. With increasing the laser beam speed it decreases almost 1.5 times. In glue coatings reinforced with B4C particulates by laser remelting, the bonding strength is lower by 1.2–1.4 times in comparison with plasma coating.

Opis:: Fe-C-Cr-Nb alloy steel surfacing layers with different contents of C and Cr were prepared on 45 steel base metal by selfshielded flux-cored wires with distinct amounts of high carbon chromium iron addition and melt arc surfacing. The composition and microstructure changes of the surfacing layer were tested and analyzed. The surfacing test plate was processed into a pulling specimen, and the bonding strength between the surfacing layer and the 45 steel base metal was tested with a self-designed pulling test method. The fracture location of the pulling specimen and fracture characteristics were observed by a metallurgical microscope and a scanning electron microscope. The result shows that with the increase of the amount of high carbon chromium iron added to flux-cored welding wire, the content of C and Cr in the surfacing layer increases, and the NbC hard phase disperses. The microstructure of the steel matrix changes from mixed martensite + residual austenite to high carbon martensite + residual austenite, and then independent austenite appears. The hardness of the surfacing layer first increases and then decreases. The bonding strength between the surfacing alloy and the 45 steel base metal first decreases and then increases, and the fracture location is at the bottom of the surfacing layer or the fusion zone with mostly quasi-cleavage characteristics. When the additional amount of high carbon chromium iron reaches 13%, thee pulling specimen exhibits significant deformation with the highest bonding strength, and the fracture is close to the fusion line, where there are numerous tearing edges and shallow dimples.
