Corrosion Resistance of TiN and CrN Coatings with Arc Ion Plating on 201 Stainless Steel Surface
摘 要
利用弧光离子镀设备，对201不锈钢表面进行离子沉积TiN薄膜和CrN薄膜。分别在3.5% NaCl 溶液、1 mol·L-1 NaOH溶液和1 mol·L-1 H2SO4溶液中进行电化学腐蚀性能测试。结果表明, 通过弧光离子镀技术在201不锈钢表面分别形成了厚度为1.2 μm的致密TiN薄膜和3 μm的致密CrN薄膜; 201不锈钢、TiN薄膜和CrN薄膜在3.5%的NaCl溶液中耐蚀性相当; 在1 mol·L-1的NaOH 溶液中，TiN薄膜的耐蚀性约是201不锈钢的2倍，CrN薄膜的耐蚀性是201不锈钢的24倍，TiN薄膜的12倍; 在1 mol·L-1的H2SO4溶液中，TiN薄膜和CrN薄膜的耐蚀性相比201不锈钢分别提高20倍和26倍。

Abstract
201 stainless steel was plated with TiN and CrN coatings by arc ion plating. Electrochemical corrosion was tested in 3.5% NaCl solution, 1 mol·L-1 NaOH solution and 1 mol·L-1 H2SO4 solution. The results show that 1.2 μm dense TiN coatings and 3μm dense CrN coatings were respectively formed by arc ion plating on the surface of the 201 stainless steel. In 3.5% NaCl solution, the corrosion resistance of TiN coatings and CrN coatings are equitement to that of 201 stainless steel. In 1 mol·L-1 NaOH solution, the corrosion resistance of the TiN coatings was twice of 201 stainless steel. The corrosion resistance of the CrN coatings was about 24 times of 201 stainless steel and 12 times of TiN coatings. In 1 mol·L-1 H2SO4 solution, the corrosion resistance of TiN coatings and CrN coatings strengthen 20 times and 26 times of 201 stainless steel, respectively.
