/Cu复合材料的腐蚀速率随温度和腐蚀介质浓度的增加而显著增大

充分细化Al

颗粒和适当延长球磨时间有利于改善其耐蚀性能。

Abstract

particulate reinforced copper matrix composites were prepared by mechanical alloying combined with powder metallurgy technique.The corrosion rate of the composites was tested by mass loss under different acid corrosion solution

and the sample surface morphologies were observed by SEM.The results show that the corrosion rate of the composites prepared is increased obviously with increasing in the medium temperature and the acid concentration.The corrosion resistance can be improved by fully refining Al

particles and appropriately prolonging ball milling time.
