Abstract:In this study, plasma sprayed Al2O3‐Cr2O3 coatings with different contents of graphene nanosheets were prepared for investigating effects of the graphene on microstructure, mechanical properties and wear behavior of the coating. The experimental results showed that graphene increased the porosity and the micro‐hardness of the coating. But excessive graphene decreased the micro‐hardness remarkably. Besides, the anti‐crack initiation and propagation abilities of the coatings with graphene improved significantly.… Show more
