摘　　要：稀有金属钨属于难熔金属,具有良好的化学稳定性以及高温特性,广泛应用于现代工业及国防军工领域。然而钨资源是不可再生资源,价格昂贵且加工困难,极大地限制了它的应用。采用各种表面工程技术在基体材料表面制备钨及其合金功能涂层,赋予基体材料以优异的物理及化学性能,既在一定程度上拓宽其应用范围,又节约了资源。文中综述了目前国内外制备钨及其合金涂层的主要技术手段,并对各技术手段的特点及研究现状进行了对比分析,最后对钨基合金涂层的发展方向进行了展望。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 becomes 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 excellent physical and chemical properties, not only broaden its application scope, but also save tungsten resources. 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.
