| 摘 要： | 以Ni/Al、NiCr为粘结层材料 ,Cr2 O3 为陶瓷层 ,用等离子喷涂技术在 45 # 钢上制得了Ni/Al Cr2 O3 和NiCr Cr2 O3 双层涂层 ,通过电化学方法对带涂层的试样的腐蚀行为进行了研究 ,并采用扫描电镜对双层涂层的腐蚀形貌进行了分析。结果表明 ,在有盐性介质存在的情形下 ,NiCr比Ni/Al有更好的耐蚀性。

| Abstract: | The Ni/Al Cr 2O 3 and NiCr Cr 2O 3 double layer co atings were prepared on the 45 steel by plasma spraying and the corrosion resist ance of Ni/Al and NiCr intermediate layer has been studied in this paper by elec trochemistry experiments as well as SEM observation. The study shows that NiCr h as better corrosion resistance than Ni/Al in salty medium. |
