ROLE OF WEAR RESISTANCE COATING PARAMETERS ON MAGNESIUM ALLOYS- A REVIEW

In this review paper, various techniques involved in improvement of wear resistance of composite coated magnesium and its alloy are studied. The tribological analysis were performed by numerous authors on the composite coated Mg as a function of reinforcement content (wt. %), sliding speed (m/s), applied load (N) and sliding distance (m) were studied. The intensified properties were obtained from various particulates reinforcement, which are distinct in their aspect ratio are coated with base metal to provide good bonding strength between them. It also highlights the different manufacturing techniques have optimum control parameters required for strengthening mechanisms to obtain the intensified properties. The volumetric wear loss testing parameters are discussed and critical point for each specific Strengthening mechanisms is compared. The related proof to justify Archad relation of the increment of hardness decreases the wear rate. The increment of wear resistance and its effects on mechanical properties are discussed in this paper.
