1 引言 有关不锈钢的磨损腐蚀研究国内外已有报道。但是对于碳钢的磨损腐蚀研究不多,尤其是在磨损腐蚀时施加阴极保护的效果如何,目前还未见报道。本工作对碳钢在3％NaCl溶液中的磨损腐蚀及阴极保护进行了定性的研究。结果表明,碳钢在3％NaCl溶液中的磨损腐蚀十分严重;对其施加阴极保护后,材料流失得到明显控制。 2 实验方法及步骤 2.1 实验装置示意图及试样尺寸分别见图 1、图2,材料的成份见表1。 1 Introduction Research on wear and corrosion of stainless steel has been reported at home and abroad. However, there is not much research on the wear and corrosion of carbon steel, especially the effect of cathodic protection during wear and corrosion. In this work, the wear and corrosion and carbon cathodic protection of carbon steel in 3% NaCl solution were qualitatively studied. The results show that the wear and corrosion of carbon steel in 3% NaCl solution is very serious. After cathodic protection is applied, the material loss is obviously controlled. 2 Experimental Methods and Procedures 2.1 The experimental setup and sample size are shown in Figure 1, Figure 2, the composition of the material in Table 1.
