In industrial applications, most materials are exposed to wear and friction because multiple conditions are used. However, the tribological properties of these materials can be improved with different techniques. One such technique that improves the frictional property of a surface is the use of self-lubricating coatings. In this study, multicomponent coatings of nominal composition Cu-Ni۳Al-MoS۲ have been sputter from the target using the best sputtering condition to get a good morphology and microstructure of the coating. The morphology and micro structure of the coatings were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and energy depressive spectroscopy (EDS). The measured microhardness of this coating was ۳۸۰ HV over ۲۵ g load. Tribological properties of Cu-Ni۳Al-MoS۲ coatings were investigated using ball-on-disk (BOD) tribometer at atmospheric condition of room temperature. These composite coatings showed a good morphology and adhesion of the coating to the substrate, also it had acceptable friction coefficient and higher wear resistance, because it has hard matrix containing Cu-Ni۳Al and MoS۲ Nano particles.
