OPTIMIZATION OF USE CONDITIONS FOR CATHODIC ARC NICKEL COATING DOPED WITH PHOSPHORUS
Keyword(s):
The results of tribological tests for a cathodic arc nickel coating doped with phosphorus are presented. The coating (thickness of 2 μm) is applied by a vacuum arc method from a nickel target with 6% phosphorus. The friction coefficient (Cfr) was determined on the tribometer, the depth of wear h of the coating after tribological tests was determined by the contact profilometry method, and the specific volumetric wear (ω) was calculated. The obtained values of Cfr, ω, and h were used to optimize the parameters of tribological tests (load and slip frequency).
