摘要
为了进一步提高稀土合金钢的耐蚀性,在其表面沉积Ni-W-P化学镀层。对Ni-W-P化学镀层的表面形貌、成分及耐蚀性进行了观察与测试。结果表明:Ni-W-P化学镀层表面的胞状物分布较为均匀,镀层中W的质量分数约为2.0%;Ni-W-P化学镀层比稀土合金钢在硫酸介质中表现出更好的耐蚀性。
Electroless Ni-W-P coating was prepared on rare alloy steel surface in order to improve the corrosion resistance of rare alloy steel. The surface morphology, composition and corrosion resistance of electroless Ni-W-P coating were observed and tested. Results showed that the cellular objects distributed uniformly on electroless Ni-W-P coating surface, and the mass friction of W element in electroless Ni-W-P coating was about 2.0 %. The corrosion resistance of electroless Ni-W P coating in sulfuric acid medium was better than that of rare alloy steel in sulfuric acid medium.
