Abstract:

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.

Key words: valves of the fracturing pump, impacting-wear, sliding abrasive wear, impact abrasive wear, amount of wear, deformation
