标准摘要
[中文适用范围]： 本文件规定了用于确定轴承金属和背衬之间粘合缺陷的超声波检测方法。 该测试可以在金属多层滑动轴承上进行，该轴承由钢基或铜基材料背衬组成，内衬铅和锡基轴承金属，层厚度大于或等于 0.5 毫米。 对于铸铁背衬，本文件的适用有限制。 轴承金属和背衬之间的粘合界面反射的超声波信号用于确定粘合缺陷。 由于未定义的反射，无法在小于超声波探头直径一半的范围内的滑动表面、法兰侧、接合区域、油孔、凹槽等的边缘区域进行超声波测试。 这同样适用于在结合处带有燕尾键槽的轴承。 超声波粘合测试不适用于燕尾榫的边缘。 只能通过 ISO 4386-3 中规定的渗透测试方法来评估从背衬到轴承金属（端面或接合面）的可见过渡处的粘合力。 本文档仅详细描述脉冲回波方法。 在本文件的含义内，超声波方法仅允许对粘合进行定性评估，而不能定量测定粘合强度。 超声波粘合测试仅在粘合和粘合缺陷之间有所不同。 [外文原描述]： This document specifies an ultrasonic testing method for determining bond defects between the bearing metal and the backing. The test can be performed on metallic multilayer plain bearings consisting of steel- or copper-based material backings lined with bearing metal based on lead and tin, with layer thicknesses greater than or equal to 0,5 mm. For cast iron backings, this document is applicable with restrictions. The ultrasonic signal reflected by the bond interface between the bearing metal and the backing is used to determine bonding defects. Ultrasonic testing is not possible on edge zones of sliding surface, flange sides, joint areas, oil holes, grooves, etc. in a range of less than half the diameter of the ultrasonic probe because of undefined reflections. The same applies to bearings with dovetail keying grooves at the bond. Ultrasonic testing of bond does not apply along the edges of the dovetails. Evaluation of the bond on the visible transition from the backing to the bearing metal (on end faces or joint faces) is only practicable by the penetrant testing method specified in ISO 4386-3. This document only describes in detail the pulse-echo method. Within the meaning of this document, the ultrasonic method only permits a qualitative evaluation of the bonding and not a quantitative determination of the bond strength. The ultrasonic bond test differs only between bond and bond defect.
