Az91d Magnesium Alloy

To improve the wear property of magnesium alloy, wear-resistant TiC and in-situ ZrC co-reinforced Zr-based amorphous composite coating has been fabricated on AZ91D magnesium alloy by laser cladding using mixed powders of Zr52.5Cu17.9Ni14.6Al10Ti5-TiC. The microstructure of the coating was characterized by XRD and SEM techniques. The wear resistance of the coating was evaluated under dry sliding wear test condition. The results show that the coating mainly consists of amorphous and different crystalline phases. The coating exhibits excellent wear resistance due to the recombination action of amorphous and crystalline phases, and the wear resistance improves further with the increase of TiC content. The main wear mechanism of the coating and the AZ91D sample are different, the former is abrasive wear and the latter is adhesive wear.
