摘　　要：探讨瑞士Bracker钢领与国产轴承钢钢领的组织结构与性能。从微观组织、表面合金层、力学性能等方面对瑞士Bracker钢领与国产轴承钢钢领进行了对比分析。结果表明:瑞士Bracker轴承钢晶粒直径较小,马氏体较为精细,有较高的碳化物含量;表面镀铬层结构致密,与基体结合良好并呈网状沟纹,提高了耐磨性能。指出:应改善国产轴承钢钢领镀铬层及与基体的结合质量,采用松孔处理工艺,可获得具有一定密度和深度的网状沟纹,提高国产钢领的耐磨损性能。Organizational structure and property of Switzerland Bracker ring and domestic bearing steel ring were discussed. Switzerland Bracker ring and domestic bearing steel ring were contrasted and analyzed from microstructure, surface alloy layer and mechanical property. The resuh shows that grain structure of Switzerland Bracker is smaller, the mashiti is finer,the carbide content is higher. The density of surface chromium layer is compacted and bonded well in web reticular groove. It is pointed out that chromium layer and bonding quality of domestic bearing steel ring should be improved. Loose hole processing should be adopted to acquiring certain density and depth web reticular groove and improve domestic ring wear resistance.
