Abstract

Bimetalik veya katmanlı malzemeler ileri mühendislik malzemeleri içinde önemli bir grup olup bu malzemeler çekirdek konumundaki parçacığın fiziksel, mekanik ve termal özelliklerinin geliştirilebildiği malzemelerdir. Bundan dolayı bu çalışmada akımsız kaplama yöntemi ile gümüş kaplı bakır bimetalik parçacıkların üretimi araştırılmıştır. Bu çalışmada ayrıca, akımsız kaplama yönteminde iyon yakalayıcı/indirgeyici ajan miktarının kaplama sonucunda elde edilen bimetalik parçacıkların fiziksel özellikleri üzerine etkisi incelenmiştir. Gümüş kaplı bakır parçacıklarının morfolojisi, mikro yapısı ve gümüş tabaka kalınlığı taramalı elektron mikroskobu ve X-ışını kırınımı ile karakterize edilmiştir. SEM incelemeleri bakır parçacıklar üzerinde 0.873 – 2.3 μm aralığında gümüş kaplama tabakasının varlığını ortaya koymuştur. Bu sonuç akımsız kaplama yöntemiyle bakır parçacıkların üzerinde başarılı bir şekilde gümüş kaplama tabakasının sentezlenebildiğini göstermiştir. Böylece bakırın düşük maliyeti ile gümüşün yüksek termal iletkenliği ve oksidasyon direnci tek bir metal parçacık bünyesinde birleştirilmiştir.

Fabrication and characterization of Cu-Ag bimetal particles by electroless coating method

Abstract

Bimetallic or layered materials are an important group of advanced engineering materials, which are the materials where the physical, mechanical and thermal properties of the core particle can be improved. Therefore, in this study, the fabrication of silver-plated copper bimetallic particles was investigated by electroless coating method. Moreover, in this study, the effect of the amount of ion trapping / reducing agent in the electroless coating method on the physical properties of the bimetallic particles obtained as a result of the coating was investigated. Morphology, microstructure and silver layer thickness of the silver coated copper particles were characterized by scanning electron microscope (SEM) and X-ray diffraction. SEM investigations revealed the presence of a silver coating layer on copper particles in the range of 0.873 – 2.3 μm. This result showed that the silver coating layer can be successfully synthesized on copper particles by using the electroless coating method. Thus, low cost of copper and high thermal conductivity and oxidation resistance of silver are combined in a single metal particle.
