摘要
通过研究轴承钢GCr15SiMn试片与渗碳钢G20Cr2Ni4A试片的接触疲劳寿命水平得知,渗碳钢G20Cr2Ni4A试片的各项寿命指标均高于轴承钢GCr15SiMn试片,且渗碳钢G20Cr2Ni4A试片的接触疲劳寿命是轴承钢GCr15SiMn试片接触疲劳寿命的3.75倍。
By studying the contact fatigue life level of bearing steel GCr15SiMn and carburized steel G20Cr2Ni4A,it is found that the life indexes of carburized steel G20Cr2Ni4A are higher than that of bearing steel GCr15SiMn,and the contact fatigue life of carburized steel G20Cr2Ni4A is 3.75 times of that of bearing steel GCr15SiMn.
