1、适用范围 本标准规定了采用铸造、烧结或电镀方法制造,由钢和铅基、锡基、铜基、铝基轴承合金制成的滑动轴承复合材料的硬度检验。 本标准是对现有的ISO关于硬度检验标准的补充。 硬度检验方法取决于轴承合金层厚度、合金层硬度和组织。 由于轴承合金是多相结构的组织成份。一般优先采用布氏硬度检验。只有当合金层厚度很小时才采用维氏硬度试验。 2、参考标准 1, the scope This standard specifies the use of casting, sintering or electroplating methods, the steel and lead-based, tin-based, copper-based, aluminum bearing alloy bearing made of the hardness of composite materials testing. This standard is on the existing ISO hardness test standards complement. Hardness test method depends on the bearing alloy layer thickness, alloy layer hardness and texture. As the bearing alloy is multi-phase structure of the organizational composition. Generally preferred to use Brinell hardness test. Vickers hardness test is only used when the thickness of alloy layer is very small. 2, reference standard
