| 介绍了一种同时利用等离子尖端放电、空心阴极效应和反应气相沉积技术,在碳钢表面形成具有扩散层和沉积层的TiN渗镀层新工艺技术.将该TiN渗镀试样与1Cr18Ni9Ti不锈钢和Q235钢在1 mol/LH2SO4溶液和3.5%NaCl溶液中,分别进行电化学腐蚀对比试验.结果表明：TiN渗镀层在酸性溶液中的耐蚀性能比1Cr18Ni9Ti不锈钢和Q235钢分别提高了1.4和4.2倍.在盐水中的耐蚀性能比Q235钢提高了182.6倍,但比1Cr18Ni9Ti不锈钢耐蚀性能稍差.渗镀TiN层耐酸性溶液腐蚀性能优于耐盐水腐蚀性能. |

| Abstract: |
| A new technique of synthesized TiN permeation layer composed of diffusion layer and deposition layer on the surface of carbon steel using plasma point discharge, hollow cathode effect and reactive vapor deposition technique was firstly introduced. The electro-chemical corrosion tests for TiN permeating samples, stainless steel 1Cr18Ni9Ti and Q235 steel substrate,in 1 mol/L H2SO4 solution and 3.5 % NaCl solution were carried out. The results showed that,in acidic solution the corrosion resistance of TiN permeation layer was increased almost 1.4 and 4.2 times than stainless steel and Q235 steel substrate. In salt water its corrosion resistance was increased nearly 182.6 times than Q235 steel substrate, but a little lower than stainless steel. Therefore the corrosion resistance of TiN permeating samples in acidic solution was stronger than that in salt water. |
