摘　　要：为研究镀镍异形钨合金零部件的抗腐蚀性能,进行了实际形状W-Ni-Cu合金零部件高温水雾腐蚀试验,并对比分析零部件不同位置镀层在腐蚀前后的变化情况。结果表明:W-Ni-Cu镍镀层具有比基底材料优越的抗高温水雾腐蚀的能力,可以有效延缓合金零部件的腐蚀失效;镀镍后,形状复杂的W-Ni-Cu合金零部件腐蚀失效的主要因素是镀层在边角处与基底的结合强度低。In order to study the anti-corrosion property of special-shaped W-Ni-Cu tungsten alloy part with nickle coating, the corrosion behavior of W-Ni-Cu real part was examined using high temperature water spraying test, the corrosion surface images of the Ni coating in different zone before and after corrosion were analyzed. The results show that the Ni coating has higher anti- corrosion property than the substrate materials, the low bonding strength between the coating and the substrate at the edge of the special-shaped part is the major cause of corrosion failure.
