Research Progress of Cermet Reinforced Iron-based Composite Coating Prepared by Laser Cladding

Aiming at the current development situation of iron-based cermet coating, the ceramic type and properties were introduced. The commonly preparation methods, mechanical added method and in-situ synthesis technique were reviewed,their fundamental characteristics were also investigated. The ways that improve synthetic performance of composite coating were analyzed. Finally, the existing problems were pointed out, and the development foreground in the future was prospected.
