镍-磷-锌盐纳米复合化学镀层抗腐蚀性能的研究
摘要:
研究了硅钢片上镍-磷与纳米微粒磷酸锌、锡酸锌、硅酸锌的复合化学镀,讨论了纳米微粒用量对镀层抗腐蚀性能的影响.用扫描电子显微镜(SEM)观察外貌;称重法测定厚度;通过加速腐蚀实验、高温氧化实验、抗粘性实验等多种方法测定其耐腐蚀性能.结果表明:在最佳施镀条件下纳米微粒用量在0.5 g/L时可得光亮、致密、耐腐蚀性不仅优于硅钢片,甚至优于相近厚度的镍-磷化学镀层的纳米复合材料镀层.

Corrosion Resistance Investigation of Electroless Composite Coatings Consisted of Nickel-Phosphorus-Nanometer Zinc Salt
Abstract:
The corrosion resistance of the electroless composite coatings consisted of nanometer zinc salt and nickel-phosphorus on the surface of silicon-steel have been investigated as function of nanoparticle concentrations.The corrosion resistance tests include accelerated corrosion, high temperature oxidation and adhesiveness resistance tests.The coating thickness and morphology were detected by weighting and SEM observation.The results showed that when nanometer particle concentration was of 0.5 g/L, the surface of the coating was homogeneous and polishing with corrosion resistance superior to silicon-steel specimen and even to nickel-phosphorus coating.
