| 摘 要： | 为了提高AZ31镁合金的耐磨性能并扩大其在相关领域的应用，采用化学复合镀技术在AZ31镁合金基体上制备了Ni-P—TiN（纳米）复合镀层，同时制备Ni—P镀层进行比较。研究了复合镀层形貌、成分、硬度和耐磨性能与镀液中纳米TiN颗粒含量的关系。结果表明，复合镀层和Ni—P镀层表面都是由胞状物排列而成；纳米TiN颗粒沉积于Ni—P—TiN（纳米）复合镀层中。当镀液中纳米TiN颗粒浓度为3g／L时，复合镀层硬度达最大值，为826HV，而Ni—P镀层只有508HV；同时复合镀层表现出优异的耐磨性能，在同等条件下其磨损失重只有Ni—P化学镀层的25％。

| Abstract: | Electroless Ni-P coating containing nano-TiN was deposited on the surface of AZ31 magnesium alloy.The effects of concentration of nano-TiN in the bath on the microstructure,component,hardness and wear resistance of the composite coating were investigated.The results show that the Ni-P-nanoTiN composite coating and Ni-P coating are both made up by grains.The nano-TiN particles are distributed in the Ni-P-nanoTiN coating,and the content of nano-TiN in the composite coating increases with increasing the concen... |
