摘要
利用闭合场非平衡磁控溅射离子镀技术在高速钢表面制备Cr-C镀层。采用电化学腐蚀法研究了Cr-C镀层、电镀Cr层及高速钢基体的腐蚀行为.结果表明,在1 mol/LNaCl、1 mol/LHCl及7.5 mol/LNaOH溶液中,闭合场非平衡磁控溅射离子镀制备的Cr-C镀层的耐蚀性优于电镀Cr镀层,并且其Cr含量越高耐腐蚀性越好.
The Cr-C coating was prepared by means of a closed field unbalanced magnetron sputter ion plating technique on high speed steel. Then the corrosion behavior of the high speed steels without and with the Cr-C coating was studied in 1 mol/L NaCl,1 mol/L HCl and 7.5 mol/L NaOH solutions respectively. For comparison steel samples with an ordinary electroplated Cr coating were also tested. The results showed that the corrosion resistance of Cr-C coating was better than that of Cr coating prepared by electroplating,and the higher the content of Cr in the Cr-C coating,the better the corrosion resistance.
