对高比重钨合金材料在江津、万宁试验站的自然环境试验（贮存与户外暴露）和实验室进行浸泡腐蚀试验、力学性能测试、扫描电镜（SEM）断口分析，结果指出钨合金材料有较强的抗腐蚀能力，在自然环境中有粘接相腐蚀的倾向，使塑性下降。
By immersion test, natural environmental test( storage test, exposure test) of the high gravity tungalloy at Jiangjin and Wanning test station, and mechanical capability test and SEM fractograph analysis of tungalloy after test, the following results were gained. Tungalloy has good capability of corrosion prevention. Bonding phase of tungalloy has corrosion inclination in natural environments and trend of plasticity drop is resulted.
