标准范围

本文件规定了一种无损渗透检测方法，用于确定轴承滑动表面的粘结缺陷和不连续性。采用穿透法进行检测a） 多层滑动轴承端面和接合面上轴承衬垫/轴承材料之间过渡区域的粘结缺陷，无法通过ISO 4386-1中规定的超声波检测方法检测到，以及b） 轴承滑动面的不连续性。穿透法原则上适用于成品多层滑动轴承。粘结试验通常在铸造多层滑动轴承上进行，其衬垫由钢、铸钢或铸青铜组成。它也可用作非生产方法，以帮助检测其他轴承材料类型的制造工艺缺陷。由于轴承材料和轴承衬板之间不可能存在粘结，因此无法对不能镀锡或难以进行镀锡的轴承衬板（如珠光体铸铁、防锈钢和铸铝）进行测试。

This document specifies a non？destructive penetrant testing for determining bond defects and discontinuities in the sliding surface of the bearing.The penetration method is used to detecta) bond defects in the transitional area between the bearing backing/bearing material on the end faces and joint faces of multilayer plain bearings which cannot be detected by the ultrasonic testing method specified in ISO 4386？1, andb) discontinuities in the sliding surface of the bearing.The penetration method is applicable, in principle, to finished multilayer plain bearings.The bond test is usually carried out on cast multilayer plain bearings, with a backing consisting of steel, cast steel or cast bronze. It can also be used as a non-production method to aid detection of manufacturing process defects with other bearing material types. Bearing backings which cannot be tin-plated, or only with difficulty, such as perlitic cast iron, rust-resistant steel and cast aluminium, cannot be tested since no bond is possible between the bearing material and bearing backing.
