Abstract
The dry sliding wear behavior of Cu-Cr-Zr alloy prepared by electromagnetic horizontal continuous casting was investigated. The wear behavior of the studied alloy was discussed in terms of friction coefficient, mass loss/sliding, specific wear rate and wear mechanism. The results indicate that with the increasing normal load and sliding velocity, the friction coefficient of Cu-Cr-Zr alloy decreased monotonically, the mass loss/sliding and specific wear rate increased. By wear surface morphology and composition analysis, the wear mechanisms were discussed preliminary. Oxidation and abrasion mechanisms dominated at the lower sliding velocities and loads. Increasing loads and velocities led to a combination of oxidation and adhesion. Plastic deformation was dominant for the higher applied load and sliding velocities.
