EFFECT OF VACUUM-PLASMA HARDENING OF THE ROLLING ELEMENT ZRN COATING FOR LIFE BEARING
Analysis and classification methods for improving of durability of rolling bearings, influence the process of vacuum-plasma hardening of the rolling element bearings ZrN coating of varying thickness on the characteristics of durability of angular contact ball bearing, MPZ 6305 are made. Also the analysis of causes of failures of bearings of tested parties is made and the influence of the thickness of the coating on the wear characteristics and durability of test frictional units is established. Hypotheses are presented to explain the positive impact of the coating to increase bearing life.
