Bu çalışmada, ağırlıkça %10, %20 ve %40 Bor Karbür (B 4 C) içerikli Al matris partiküllerin ve kompakt malzemelerin üretimi ve karakterizasyonu gerçekleştirilmiştir. B 4 C takviyeli Al matris kompakt malzemelerin elektriksel iletkenlik değerleri en düşük 6,97 %IACS ve en yüksek 20,73 %IACS olarak belirlenmiştir. Deneysel çalışmalar sonucunda, mikro yapıda ağırlıkça artan B 4 C takviyesinin yapının yoğunluğunu azaltma ve sertliğini arttırma noktasında etkisi olduğu anlaşılmıştır. Yapısında ağırlıkça %10, %20 ve %40 B 4 C içeren Al matris kompakt malzemelerin yoğunluk değerleri sırasıyla 2,622 gr/cm 3 , 2,598 gr/cm 3 ve 2,568 gr/cm 3 olarak, sertlik değerleri sırasıyla 244.34 HV(0.5), 270.16 HV(0.5) ve 290.70 HV(0.5) olarak ölçülmüştür.
In this study, copper powders with dendritic morphology were produced by the electrolysis method, and then silver coating was applied to these powders by an electroless coating method. The bulk samples were fabricated by hot pressing method using different ratios of copper and silver-plated copper powders. The results showed that the electroless silver coating layer provided a strong bond at the particle boundaries of the samples, significantly improving the physical and mechanical properties of the materials. Accordingly, the hardness, tensile strength, electrical and thermal conductivity values of the samples produced from silver-plated dendritic copper particles were determined to be approximately 98 HB, 185 MPa, 102 IACS% and 402 W mK −1 , respectively. In addition, the oxidation resistance of the sample produced from completely silver-coated copper powders is 4 times higher than that of pure copper.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
