Bearing Evaluations and Sliding Tests on Boride Coatings and Compounds

Abstract

Wear tests, consisting of journal bearing tests and sliding friction tests, were conducted on bonded specimens produced by electrochemical deposition from a fused salt and on specimens made from boride powders (Cr Br2, VB2, and MoB2). Friction values and wear resistance were determined for the specimens. In general, the steels which were borided showed better wear resistance than comparable non-borided steels. No consistent correlation was obtained between crystal structure and sliding performance.
