Study on Friction and Wear Characteristics of Cu-0.8Cr-0.14Zr-0.06Mg Alloy

The electrical sliding wear of the Cu-0.8Cr-0.14Zr-0.06Mg alloy are studied by loading different lining speed and electric current in this article.The alloy sliding worn surfaces and wear mechanism are observed and analyzed by optical microscopy and SEM.The results show that the alloy solved at 920 ℃ for 30 min and aging at 450 ℃ for 180 min behaves a linear relationship between the wear volume and running speed,and the wear mechanism is adhesive wear and abrasive wear.The wear mechanism becomes adhesive wear,abrasive wear and arc induced wear after loading current.And as the current increases,the adhesive wear and arc induced wear is becoming increasingly serious.
