摘要 采用复合电沉积法制备出Cr颗粒含量不同的Ni-Cr微米复合镀层,该镀层由电镀Ni和微米Cr颗粒(～2.4μm)组成.900℃20 h高温氧化实验结果表明,当Cr含量接近32 mass%时,该复合镀层能够形成一层连续的Cr_2O_3氧化膜.通过对微米Cr颗粒含量不同的Ni-Cr复合镀层氧化性能的对比,讨论了其氧化机理. Ni-Cr microcomposite coatings were prepared on Ni-plates by co-electrodeposition of Ni with microparticles of Cr.The oxidation of the composite coatings at 900℃in air was investigated and then the formed oxide scales were examined by SEM with XRD.The results showed that continuous Cr_2O_3 scale could form on the composite coating when the Cr content was closely to 32 mass%.The oxidation behavior of the composite coatings was discussed in detail.
