Enhancing the tribological and mechanical properties of M50 steel using solid lubricants - A detailed review

Recent strides in contact mechanics of M50 steel offer unique opportunities for better and more control of its tribological behavior and mechanical properties under different contact and surrounding conditions. Most researchers have focused on the solid lubricants on M50 steel as the key strategy for improving the tribological properties. In this paper, we have selected a wide range of previous late studies to discuss the different mechanisms leading to an improvement in the tribological properties of M50 steel via solid lubricants. A discussion of M50 steel industrial applications is also reviewed. The main objective is to develop an exhaustive understanding of the tribological behavior of M50 steel with solid lubricant additives under different conditions and also provide some prospects to be considered for future work.
