In this paper, the methods of manual arc surfacing and soakage surfacing and oxyacetylene flare surfacing and influence melting were used to manufacture metal basis ceramics composite wearable layer. The technical process of every methods were depicted. The surfacing technical test and slurry wear test of tungsten carbide ceramics composite wearable layer were introduced. According to the capability characteristic of surfacing layer and the distributing state and melting decompose degree of tungsten carbide particles in surfacing layer and the slurry wear shape characteristic of surfacing layer, the wear mechanics of tungsten carbide ceramics composite wearable material and the effects of basis material and tungsten carbide particles were analyzed. The surfacing heat source and surfacing technical influence upon tungsten carbide particles' shape and tungsten carbide ceramics composite wearable surfacing layer's capability were discussed.
