亚微米Ni-Cr-Al复合镀层的制备及结构表征

摘要

The submicron Ni-Cr-Al composite coatings were prepared by adding a certain amount of sub micron and Al par-ticles into the electroplating solution by adding a certain amount of sub micron grade Cr. The structure of the coating was char-acterized. The high temperature oxidation behavior of the coating was studied. The structure analysis showed that the coating was compact.%采用复合电沉积技术，通过向电镀液中加入一定量亚微米级别Cr、Al颗粒制备了亚微米Ni-Cr-Al复合镀层。表征了镀层的结构，研究了镀层的高温氧化行为，结构分析表明，该镀层结构比较致密，氧化实验表明该镀层具有抗氧化性。
