化学镀铜石墨粉及其铜基复合材料的性能
Characteritics of electroless copper-coated graphite and its copper matrix composites
摘要
Abstract
Aimed at improving wettability of copper and graphite,this paper introduces graphites surface-coated by copper using electroless plating technology,and copper coated graphites/Cu-matrix composites fabricated by vacuum sintering process of powder metallurgy.The paper describes the copper coated graphites characterized by TG-DTA、XRD、FT-IR、SEM method,and surface morphology of graphite particles in copper coated graphites/Cu-matrix composites valued by SEM at different heat-treatment temperatures.The results shows that,copper coating layer is subject to oxidation when exposed to above 250 ℃ in air,and is subject to oxidation by coated graphite when exposed to above 500 ℃.The FT-IR spectra of copper coated graphites has weaker absorption peaks than that of noncoating graphites,and copper coating layer gives a prominent spheroidization when copper coated graphites/Cu-matrix composites is subject to heat treatment in vacuum of above 800 ℃.关键词
