Plain bearings. Metallic multilayer plain bearings-Destructive testing of bond for bearing metal layer thicknesses greater than or equal to 2 mm
滑动轴承 金属多层滑动轴承
Scope: 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.Cross References:ISO 4381All current amendments available at time of purchase are included with the purchase of this document.
