| 摘 要： | 采用自制的冲击腐蚀磨损试验装置,研究了湿磨弱酸性锡矿浆体系中高锰钢在静态、充氧、搅拌和冲击等复合条件下的腐蚀磨损行为,并利用失重法、电化学法和线性回归法,定量分析了腐蚀、磨损和腐蚀磨损中交互作用各分量的相对比率.结果表明:充氧和搅拌促进了氧在高锰钢表面的传质过程,使腐蚀率较静态分别增加了1.05和2.04倍;高锰钢的累积质量损失、表面显微硬度和腐蚀磨损交互作用均随着冲击功的增加而增大;在不同冲击功下,高锰钢的腐蚀增量比静态腐蚀率高15.15～25.54倍,腐蚀磨损交互作用所占比率为12.07%～26.69%,表明磨损与腐蚀之间存在着一定的协同促进作用;在冲击功为1J时,交互作用以磨损促进腐蚀为主;在冲击功为2～4J时,交互作用以腐蚀促进磨损为主.

| Abstract: | Corrosive wear behavior and the synergy of high manganese steel under static,oxygen aeration,stirring and corrosive impact abrasion conditions were investigated by using self-made impact corrosive wear tester.The corresponding proportions of individual corrosion,wear and corrosive wear synergy to the total material loss were evaluated via electrochemical method,cumulative mass loss rate analysis and linear regression analysis.The results reveal that oxygen aeration and stirring accelerate the transport of o... |
