标准范围

本文件规定了测定轴承金属和背衬之间粘结强度的拉伸试验方法。该试验可用于多层滑动轴承，轴承金属为铅、锡、铜或铝。对于测试层厚度≥ 2 mm，则需要至少额外增加1 mm的原始衬里厚度。背衬由钢、铸钢或铜合金制成。粘结强度试验不适用于带有铸铁衬垫的轴承。该试验适用于所有止推轴承和内径为衬垫的轴颈轴承≥ 90毫米。该试验可用于对比研究各种工艺和材料类型对粘结强度的影响。此外，该试验适用于生产控制和轴承生产的工艺评定。用于轴承金属和衬垫之间结合的无损超声波检测，用于轴承金属层厚度≥ 2毫米，见ISO 4386-1.

This document specifies a tensile test method for determination of the bond strength between the bearing metal and the backing. The test can be applied to multilayer plain bearings with bearing metals based on lead, tin, copper or aluminium. For tested layer thicknesses ≥ 2 mm, a raw lining thickness of a minimum additional 1 mm is necessary.The backings are from steel, cast steel or copper alloys. The bond strength test does not apply to bearings with cast iron backing.The test applies to all thrust bearings and to journal bearings with an inner diameter of backing ≥ 90 mm.The test can be used for comparative investigations into the influence on the bond strength of various processes and types of material. In addition, the test is suitable for production control and for process qualification of bearing production.For non-destructive ultrasonic testing of the bond between bearing metal and backing for bearing metal layer thicknesses ≥ 2 mm, see ISO 4386-1.
