Abstract: Tungsten，with high chemical stability and high temperature characteristics，is widely used in modern industry and military field． However，the resources of tungsten are non-renewable，the price be-comes more and more expensive and its processing is difficult． With various kinds of surface engineering technology，coating tungsten and its alloy on matrix material surface，can give the matrix materials excel-lent physical and chemical properties，not only broaden its application scope，but also save tungsten re-sources． This paper summarized the main coating technical means of tungsten and its alloy at home and abroad，the characters and research status of these technologies are introduced，the development direction of the coating is also prospected．
Key words: surface and imterface for the material; Tungsten; coating; status
