Characterization and anti-friction on the solid lubrication MoS₂film prepared by chemical reaction technique

To develop a new way to produce the molybdenum disulfide (MoS2) solid lubrication film, the following two-step chemical reaction technique was attempted. Firstly, a Mo film was prepared by multi-arc ion plating technique, and secondly the Mo film was sulfurized by a low temperature ion sulfuration technique to obtain the MoS2 solid lubrication film. This MoS2 film was a composite film consisted of MoS2 and Mo. The lubricant MoS2 is dominant in the surface and metal Mo is dominant in the deep layer. It is an ideal frictional surface. The tribological properties showed that the solid lubrication MoS2 film possessed an excellent anti-friction property.
