摘　　要：用电化学方法对电沉积法制备的非晶态Ｃｒ－Ｃ合金镀层与晶态Ｃｒ镀层在几种常见腐蚀介质中的耐蚀性进行了测定。结果表明，非晶态Ｃｒ－Ｃ合金镀层的耐蚀性均明显优于晶态Ｃｒ镀层，腐蚀速率约为晶态Ｃｒ镀层的０．５％～２． ５％。通过对镀层孔隙率和表面形貌的研究表明，非晶态 Ｃｒ－Ｃ合金镀层表面细致、均匀、无微裂纹，抑制了腐蚀微电池的形成，耐蚀性明显提高。The corrosion resistance of amorphous Cr-C alloy and crystalline Cr deposits has been investigated by electrichemical method. The results showed that the corrosion rate of amorphous Cr-C alloy deposit was as 0. 5% - 2. 5% as that of crystalline Cr deposit in common solutions. The experimental results on surface morphology and porosity were discussed.
