背景技术
目前应用的轴承材料主要分为以下几种：
1 ) 高碳铬轴承钢材料 （GB/T 18254-2002);
高碳铬轴承钢主要有 GCr9、 GCrl5、 GCr9SiMn和 GCrl5SiMn等材质。 GCr9主要用于 制造转动轴上尺寸较小的钢球或者滚子， 一般条件下工作的轴承环及滚动体； GCrl5用于制 造大型机械轴承的钢球、 滚子和轴承环； GCr9SiMn性能同 GCrl5相近， 主要用于制造尺寸 较大的轴承环； GCrl5SiMn的耐磨性和淬透性比 GCrl5高，主要用于制造大型轴承的轴承环、 钢球和滚子。
2) 渗碳轴承钢材料 （GB/T3203— 1982);
渗碳轴承材料主要有 G20CrMo、 G20Cr2Ni4 G20Cr2Mn2Mo和 G20CrM2Mo等材质， 此类型轴承钢主要用于承受冲击荷载的轴承环和滚动体。 这是因为， 此类钢经表面渗碳后， 具有良好的硬度和韧性值， 可以承受较大的冲击荷载， 如 G20Cr2Ni4渗碳轴承钢经渗碳 +热 处理后， 表面硬度 HRC62, 心部硬度 HRC43 , 渗碳深度 2.3mm， 冲击韧性值达到 68.7J/cm2。
3 ) 不锈轴承钢材料 （GB/T3086— 1982);
不锈轴承钢材料目前应用较多的是 9Crl8和 9Crl8MoV， 该类钢种主要用于制造耐蚀的 轴承环及滚动体， 如海水、 河水、 硝酸、 化工石油、 原子反应堆用轴承等。
4) 无油润滑双金属轴承材料
无油润滑双金属轴承材料是以优质低碳钢背为基体， 表面烧结铅锡青铜合金， 经数次高 温烧结和致密轧制而成铜 -钢一体的双金属带材卷制而成， 适合于制造承受中速、 高冲击载荷 的衬套、 止推垫圈等。
滚动轴承通常都在较高的转速或较大的荷载下运行， 因此， 要求滚动轴承材料须具备下 述特点：
1 ) 必须可以充分淬硬， 具有较高的硬度和耐磨性；
2) 必须具有较高的疲劳强度、 特别是工作面的抗剪切疲劳强度；
3 ) 在工作温度下， 保证轴承零件具有结构和尺寸的稳定性； 4) 对于承受冲击荷载情况下的轴承具备较大的抗冲击能力；
但是， 对于同一种材料而言， 硬度、 耐磨性和韧性、 抗冲击能力是相互矛盾的， 要求足 够高的硬度、 强度和耐磨性必然会以降低材料的韧性和抗冲击性能为代价。 虽然渗碳轴承钢 材料可在一定程度上满足工作面硬度和整体韧性的配合， 但渗碳层的碳含量不均匀性又大大 降低了工作面的抗剪切疲劳性能。如何保证在足够的硬度、耐磨性下不降低材料的冲击韧性， 同时又保证工作面具有较高的抗剪切疲劳性能， 正是本专利所解决的。
