GB/T 18329.4-2021
ActivePlain bearings—Metallic multilayer plain bearings—Part 4:Non-destructive ultrasonic transmission testing of bond of thickness greater than or equal to 0.3 mm
滑动轴承 多层金属滑动轴承 第4部分: 合金厚度≥0.3mm的结合质量超声穿透无损检测
Application Summary AI generated
This standard specifies the non-destructive ultrasonic transmission testing method for evaluating the bond quality between the bearing alloy layer and the backing in metallic multilayer plain bearings where the alloy thickness is 0.3 mm or greater. It is applied in the manufacturing and quality control of sliding bearings used in heavy machinery, automotive engines, and industrial equipment to ensure reliable adhesion and prevent delamination under operational loads.
