摘　　要：对比渗碳淬火油和无机高分子水溶性淬火液对GCr15SiMn轴承钢组织和性能的影响,结果表明:GCr15SiMn轴承钢采用渗碳淬火油淬火工艺,淬、回火后硬度为60.5 HRC,显微组织为马氏体5级;GCr15SiMn轴承钢采用无机高分子水溶性淬火液淬火工艺,淬、回火后硬度为61~67 HRC,显微组织为马氏体3级,表层3 mm内无屈氏体。无机高分子水溶性淬火液淬火工艺淬、回火后的硬度和金相组织符合JB/T 1255—2014的要求。无机高分子水溶性淬火介质淬火工艺提升了GCr15SiMn轴承钢的综合性能。The effect of carburizing quenching oil and inorganic polymer water-soluble quenching fluid on structure and properties of GCr15SiMn bearing steel is compared.The results show that the GCr15SiMn bearing steel is quenched by carburizing quenching oil,the hardness after quenching and tempering is 60.5 HRC,and the microstructure is martensite grade 5.The GCr15SiMn bearing steel is quenched by inorganic polymer water-soluble quenching fluid,the hardness after quenching and tempering is between 61 and 67 HRC,the martensite structure is grade 3 and there is no troostite in surface layer of 3 mm.When GCr15SiMn bearing steel is quenched by inorganic polymer water-soluble quenching fluid,the hardness and metallographic structure after quenching and tempering meet requirements of JB/T 1255—2014.The quenching of GCr15SiMn bearing steel by inorganic polymer water-soluble quenching medium improves comprehensive properties.
