Kind Code:
A1
Abstract:
A slider manufacturing method, comprising: manufacturing a bi-material or multi-material planar slider, such as a sliding bearing of a textile machine, by using a powder metallurgy method; using a second powdered material as a powdered raw material of a supporting material layer, and using a first powdered material as a raw material of a working material layer; laying the materials in sequence such that the second powdered material is below the first powdered material; placing a sheet that is of an undulating structure and is made of a thermally decomposable material between the second powdered material and the first powdered material as an interface construction template, wherein the interface construction template can be removed between the second powdered material and the first powdered material by means of degassing pre-sintering or degreasing, and after the interface construction template is removed, the second powdered material and the first powdered material are respectively metallurgically sintered to form the supporting material layer and the working material layer; and forming a non-linear interface structure corresponding to the undulating structure of the interface structure template in shape at a sintered interface of the supporting material layer and the working material layer. The method requires neither separate compaction of the powders nor the addition of an individual operating procedure for processing the interface.
