用电化学测试技术研究经Cr,Mo和Al离子注入表面改性碳钢在NaCL-Na_2SO_4溶液中的腐蚀行为。结果表明,Cr和Mo离子复合注入改性表面在O.5molL~(-1)NaCl-0.5molL~(-1)Na_2SO_4溶液中对减缓腐蚀和改善钝化性能很有效果。Al离子注入使改性表面的耐蚀性变劣。
The corrosion behavior of surface modified carbon steel in NaCL-Na_2SO_4 solution by Cr, Mo and Al ions was studied by electrochemical test. The results show that the combination of Cr and Mo ions into the modified surface is very effective in reducing corrosion and improving the passivation performance in 0.5 molL ~ (-1) NaCl-0.5 molL ~ (-1) Na_2SO_4 solution. Al ion implantation deteriorates the corrosion resistance of the modified surface.
