| Abstract: | Hot spraying,laser surface remelting,deposit welding and surface alloy penetrating method(in which special alloyed powder coating is used to coat mold surface,after molten metal is poured in the mold cavity,the alloy in the coating penetrates into casting surface and forms a special alloyed layer) are the important methods to obtain surface gradient composites and to improve the materials service properties and service life.Preparation procedure of surface gradient composites and their practical application are described.This can be a reference for the selection,development and preparation of wear resistant materials. |
