利用自制的微动腐蚀测试系统，研究1Cr13不锈钢在3．5％NaCl溶液中，不同的阴极保护电位下的微动腐蚀行为．结果表明：未加阴极保护时，微动使自然腐蚀电位快速负移到稳定值；微动腐蚀失重量随阴极保护电位的负移而逐渐减小，－670mV时失重量达到最小值，此后失重量随保护电位的负移而逐渐增加，电位负于－800mV时失重量大于未加阴极保护时的失重量．
The fretting corrosion behavior of 1Cr13 stainless steel in 3.5% NaCl solution at different cathodic protection potentials was investigated by using a homemade fretting corrosion test system. The results show that when the cathodic protection is applied, the natural corrosion potentials rapidly and negatively shift to a steady value when the cathodic protection is not applied. The weight loss of the micro-corrosion corrosion gradually decreases with the negative cathodic protection potential, and the weight loss reaches the minimum at -670mV. The weight gradually increases with the negative shift of the protection potential, and the weight loss when the potential is minus -800mV is greater than the weight loss without the protection of the cathode.
