Impact Fretting Wear of MoS(2)/C Nanocomposite Coating with Different Carbon Contents under Cycling Low Kinetic Energy

MoS(2)/C nanocomposite coatings were deposited on a 304 stainless steel plate by unbalanced magnetron sputtering from carbon and molybdenum disulfide targets, and the target current of MoS(2) was varied to prepare for coating with different carbon contents. The mechanical and tribological properties of the MoS(2)/C nanocomposite coating with different carbon contents were studied using a low-velocity impact wear machine based on kinetic energy control, and the substrate was used as the comparison material. The atomic content ratio of Mo to S in the MoS(2)/C coating prepared by unbalanced magnetron sputtering was approximately 1.3. The dynamic response and damage analysis revealed that the coating exhibited good impact wear resistance. Under the same experimental conditions, the wear depth of the MoS(2)/C coating was lower than that of the substrate, and the coating exhibited a different dynamic response process as the carbon content increased.
