摘　　要：对高淬透性轴承钢GCr19SiMnMo的淬透性及下贝氏体含量不同的马氏体/贝氏体复合组织和马氏体组织的摩擦磨损性能进行了研究,并与GCr15钢、GCr15SiMn钢马氏体组织进行对比。结果表明:GCr19SiMnMo钢的端淬试样完全淬透,GCr15钢淬硬层深度为8.5 mm(J8.5=58),GCr15SiMn钢的淬硬层深度为18.5 mm(J18.5=58);GCr19SiMnMo钢的马氏体组织耐磨性最优且摩擦因数最小;不同下贝氏体含量GCr19SiMnMo钢的磨损率均比GCr15钢和GCr15SiMn钢低;GCr19SiMnMo钢组织中的下贝氏体含量对耐磨性有一定的影响,下贝氏体含量越少,耐磨性越好。The hardenability of high hardenability bearing steel GCr19SiMnMo and the friction and wear properties of martensite/bainite composite(MB)with different B L contents and martensite(M)structures are investigated and compared with those of M structures of GCr15 steel and GCr15SiMn steel.The results show that:the end-hardened specimens of GCr19SiMnMo steel are completely hardened,and the depth of hardened layer is 8.5 mm(J8.5=58)for GCr15 steel and 18.5 mm(J18.5=58)for GCr15SiMn steel;the M structures of GCr19SiMnMo steel have best wear resistance and lowest friction coefficient;the wear rate of MB structure of GCr19SiMnMo steel is lower than that of GCr15 steel and GCr15SiMn steel;the B L content in structures of GCr19SiMnMo steel has a certain influence on wear resistance,the lower the B L content,the better the wear resistance.
