Spray melting using self-fluxing alloy powder can be divided into the nickel base and cobalt base and iron base and containing tungsten carbide fluxed alloy such as four series. self-fluxing alloy powder quality control all raw material are tested in terms of density, hardness and T.R.S before use. There are strict inspection on process and final products. every batch of product can be traced.

HVOF HVAF APS Small, medium grain size tungsten carbide The highest working temperature 500 ℃ Hard, dense coating, Have good wear resistance, Corrosion resistance and Sliding wear resistance. Have good microstructure and higher bond strength of smooth coating. Low resistance to oxidation resistance and corrosion resistance
