Study on Synthesis and Tribological Properties Characterization of MoS2-TiL/MoS2-TiH Nano Multilayer Coating

Benefitting from it novel structure, MoS2-TiL/MoS2-TiH nano multilayer coating possesses excellent tribological properties. The multilayer coating was prepared by varying the power of Ti target alternatively using magnetron sputtering technology. To investigate its tribological properties, more extensively analyses have been carried out on a reciprocating friction and wear testing machine under different loads. Then, wear trace morphology was studied by a confocal microscope. The friction coefficient is very stable around 0.1 ~ 0.2 at a load smaller than 20 N. Correspondingly, wear trace is narrow and the wear loss is very small under a small load. With a larger load, wear traces become wider and the lubricant only lasted for a short time. Whereas, compared to MoS2-Ti composite coating, the multilayer coating has the advantage apparently on wear resistance and lubrication.
