摘要
通过对多种材料在不同试验条件下耐冲击磨料磨损性能的初步研究 ,优选出 2 0CrMnTi材料开展了在冲击磨损、滑动磨料磨损和冲击磨料磨损条件下的进一步试验 ,分析了在各磨损与变形条件下的特点 ,对所观察到的现象与机理进行了讨论 ,得出了一些有益结论。研究表明 ,2 0CrMnTi材料经渗碳 +淬火 +低温回火处理后 ,具有较好的抗冲击磨料磨损的能力。这对研究新型压裂泵泵阀抗冲击磨料磨损性能的材料具有一定的指导意义。
Through the researches in some material's properties to resist impact abrasive wear, optimized 20CrMnTi optimized was further tested under the condition of impacting ? wear, sliding abrasive wear and impact abrasive wear, analyzed its characteristics, and discussed the appearance and forming mechanism observed. It was got some useful conclusions. The results have shown the heat ? treatment cycle of carburizing + hardening + low tempering, the 20CrMnTi would be better ability to resist impact abrasive wear. It has a guiding significance to research the new materials of resisting the wear in valves of the fracturing pump.
