Wear-corrosion behavior of ion plated thin films
- Louisiana State Univ., Mechanical Engineering Dept., Materials Engineering Program, Baton Rouge, LA (US)
The authors discuss the combined action of wear and corrosion processes investigated on Cr and TiN thin films ion plated onto 304 stainless steel and M 50 steel, respectively. A new laboratory technique was used to study the simultaneous effects of mechanical and electrochemical parameters during a sliding wear processes in a corrosive environment. The wear-corrosion studies were conducted in 0.1M NaCl using potentiodynamic polarization scans. The wear process was found to affect the materials' corrosion behavior by lowering the corrosion potential, extending the activation polarization region, and increasing the passive current density. The degree to which these changes occur is a primary function of the oxide stability and the repassivation kinetics.
