Abstract The article proposes the use of ADI cast iron as an alternative material solution for 30CrMo12 cast steel in the construction of friction systems intended for use in tribocorrosion conditions with the presence of an abradant. An independent evaluation of the resistance to tribocorrosion of the analyzed materials was made using two types of tests: a laboratory and industrial one. The industrial test was carried out using an original research stand. It made it possible to map the real operating conditions of the chain wheels of the scraper conveyor transporting a mixture of mineral abrasive and salt water. A standard tribotester with a ball-on-plate system and a model corrosion environment of 3.5% NaCl were used in the laboratory test. The research results included in the article indicate that ADI cast iron has a higher resistance to tribocorrosion than 30CrMo12 cast steel despite lower initial hardness and similar corrosion resistance. This effect may be caused by the ability to strengthen the near-surface layers of cast iron due to frictional interactions. The article also showed that the results of the comparative assessment of the tribocorrosion resistance of various materials obtained in the model systems (the laboratory test) can be as effective as the tests of real machine systems (the industrial test).

30CrMo12铸钢与ADI球墨铸铁摩擦腐蚀对比试验

摘要 本文建议使用 ADI 铸铁作为 30CrMo12 铸钢的替代材料解决方案，用于制造摩擦系统，用于存在磨料的摩擦腐蚀条件。使用两种类型的测试对所分析材料的耐摩擦腐蚀性能进行了独立评估：实验室测试和工业测试。使用原始研究台进行工业测试。它可以绘制输送矿物磨料和盐水混合物的刮板输送机链轮的真实操作条件。在实验室测试中使用了带有球板系统的标准摩擦测试仪和 3.5% NaCl 的模型腐蚀环境。文章中包含的研究结果表明，尽管初始硬度较低且耐腐蚀性能相似，但 ADI 铸铁具有比 30CrMo12 铸钢更高的耐摩擦腐蚀性能。这种效果可能是由于摩擦相互作用而增强铸铁近表面层的能力造成的。文章还表明，在模型系统（实验室测试）中获得的各种材料的耐摩擦腐蚀性能的比较评估结果可以与真机系统的测试（工业测试）一样有效。
