In this study, molybdenum disulfide (MoS2),purity 99%, nanoparticles have been used as solid-state lubrication, due to it havinga low coefficient of friction and high wear resistance. In which MoS2 particles havebeen distributed with 1.69 x 1015 particles per m2 over the steel disc’s surfaceagainst the steel pin using a pin on disc tribometer machine. The pin on disctechnique was used to study the friction coefficient behaviour of the MoS2distribution particles and the position depth of the steel pin on the steel disc surfacewhen the ambient environment was air and humidity. It was used to examine thetribological behaviour of the steel pin on the steel disc surface with no distributionof MoS2 nanoparticles and also for a steel pin on steel disc with a distribution ofMoS2 nanoparticles. Then, the morphologies and microstructures of thedistributions of MoS2 nanoparticles were characterized using Scanning ElectronMicroscopy (SEM). In a result, the distribution of MoS2 nanoparticles have resultedin a lower friction coefficient and higher wear resistance compared with only steelpin on steel disc surfaces.
