利用专门改进的料浆罐式设备通过旋转失重和动、静态极化测试，系统研究了外加电位对０Ｃｒ１８Ｎｉ９Ｔｉ不锈钢在１０％Ｎ＿２ＳＯ＿４＋１５％刚玉砂（室温）介质中冲刷腐蚀行为的影响，并借助扫描电镜对冲刷腐蚀试样进行了表面形貌观察。结果表明，阴极保护能显著降低冲刷腐蚀速率，保护度可达７３．６％。施加阳极电位可出现３种效果：比自腐蚀电位稍正的１区，冲刷腐蚀速率显著提高；稳定钝化的Ⅱ区，冲刷腐蚀速率显著下降，保护度可达６４．５％；过钝化的Ⅲ区，产生晶间腐蚀，冲刷腐蚀速率再度升高。合适的阳极保护电位范围为：０－０．８Ｖ（ＳＣＥ）。
The effects of applied potential on the corrosion behavior of 0Cr18Ni9Ti stainless steel in 10% N_2SO_4 + 15% corundum (room temperature) media were systematically investigated by means of rotating weight loss and dynamic and static polarization tests with a specially modified slurry tank device. Scanning electron microscopy The surface morphology of the eroded samples was observed. The results show that cathodic protection can significantly reduce the erosion rate, the degree of protection up to 73.6%. There are three kinds of effects when the anodic potential is applied: a slightly positive corrosion zone compared with the self-corrosion potential, the erosion and corrosion rate is significantly increased; in the steady and passivated zone Ⅱ, the erosion and corrosion rate is significantly decreased, with a degree of protection of 64.5% Ⅲ area, resulting in intergranular corrosion, corrosion erosion rate increased again. A suitable range of anodic protection potentials is 0-0.8V (SCE).
