根据腐蚀磨损交互作用理论,采用局部阴极极化曲线与电位-时间曲线结合的方法,研究了衬板用铬钢材料在模拟矿浆中受冲击磨损时的腐蚀行为。结果表明,冲击磨损作用能加剧了材料的腐蚀,选择球磨机衬板材料时,除检验其耐磨性能外,还必须考虑材料在矿浆中的耐蚀性。 According to the interaction theory of corrosion and wear, the corrosion behavior of the chrome-plated steel plate subjected to impact and wear in the simulated pulp was studied by the combination of local cathodic polarization curve and potential-time curve. The results show that the impact of wear and tear can aggravate the material corrosion, the choice of ball mill liner material, in addition to testing its wear resistance, but also must consider the corrosion resistance of the material in the pulp.
