| Abstract: | In order to evaluate the possibility of applying cobalt alloy coating to the sliding-rolling contact friction pair under fluid lubrication condition, some experiments on the contact fatigue resistence were conducted for several kinds of cobalt alloy coatings. The test results show that among the cobalt alloy coatings investigated, Co-1 with lowest carbon content is the best. The mechanism for the contact fatigue resistance coatings were analysed and discussed based on stress analysis and micro-structure observation by using TEM. An empirical formula for estimating fatigue life and the depth of alloy coating is derived from the experimental results. |
