Benefits of technology

The patent describes a new method for making a resin layer on a base. Instead of using a porous layer, a resin material is directly applied to the base, making it easier to control the thickness and prevent peeling. The base has recesses on its surface, and the resin layer is secured in these recesses using an anchor effect. This allows for a smoother surface and reduces the time required for manufacturing. The new method also allows for the formation of convex-concave portions on the surface of the resin layer without needing additional machining equipment.

Problems solved by technology

From a bonding perspective, the possible combinations between different types of base materials such as metal backing and different types of porous sintered layer materials are generally limited.
It is thus, for instance, difficult to change the sintering temperature.

Embodiment Construction

[0066]Next, an embodiment will be described with reference to FIGS. 1 to 3 and 7 and 8.

[0067]Slide member 11 of the present embodiment is obtained by preparing a base metal backing 12 made, for instance, of steel, providing impregnated layer 13 by forming recess 15 on surface portion 12b of base metal backing 12, and impregnating and covering impregnated layer 13 with resin layer 14 primarily composed of PEEK.

[0068]In order to verify the bonding force, in other words, the shearing stress of base 12 and resin layer 14 of slide member 11 of the present embodiment, EXAMPLES based on the embodiment and COMPARATIVE EXAMPLES based on conventional porous sintered configuration were prepared and were screened through a shear test.

[0069]More specifically, EXAMPLES were prepared as follows.

[0070]First, a steel backing plate serving as the base and having a thickness of 20 mm was prepared. Then, recesses were formed, by wire cut electrical discharge machining, on the surface portion of the bas...

Abstract

A slide member provided with a base, an impregnated layer, and a resin layer. The base made of metal or ceramic. The impregnated layer is defined on a surface portion of a sliding side of the base by forming a recess on the base. The resin layer impregnates the impregnated layer so as to cover a sliding side surface of the base.

Description

TECHNICAL FIELD[0001]The present invention relates to a slide member provided with a resin layer and a method of manufacturing the same.BACKGROUND[0002]Some slide members are provided with a resin layer that serves as a sliding portion. The resin layer is typically made of PEEK (Polyetheretherketon) that exhibits outstanding sliding properties such as seizure resistance, wear resistance, and mechanical strength.[0003]The resin which forms the resin layer, does not easily establish a chemical bond with metal which is a different type of material. Thus, when the resin layer is applied directly on a metal base serving as a support layer, the resin layer may easily peel from the base. Such being the case, patent document 1 teaches providing a porous sintered layer, obtained by sintering lead bronze powder, on the base and impregnating a portion of the resin layer into the porous sintered layer. Patent Document 1, i.e. JP H08-210357 A teaches that the resin layer is secured on the base t...
