Abstract：Using closed-field unbalanced magnetron sputtering technique, CrC composite coating was prepared on the steel ball substrate of bearing 6204. The vibration performances of ball bearing coated with CrC composite coating on the steel ball and uncoating general ball bearing were tested and been comparatived analysis. Results indicate that, Compared to the uncoating steel ball bearing, CrC coating steel ball bearing significantly reduces the value of bearing vibration, especially under the high-speed or high loads conditions damping effect is particularly significant. The smooth performance of bearing vibration is obviously enhance.
