摘要
借助ＤＣ－１５０多冲试验机，探讨了非组织因素时２０ＣｒＭｎＭｏ钢表面剥落的影响。结果表明，端面起始剥落寿命主要取决于冲击能量和冲击频率，也和端面粗糙度有关。
he influence of non-microstructure factors on peeling off of 20CrMnMo steel was investigated by using DC-150 machine.the results showed that the life of initial peeling off depending on impact energy and impact frequency,and it is also related to surface roughness.
