Abstract
Abstract A method of producing a sliding composite material. The method comprises the step of: forming an adhesive layer bonded to the surface of a metal strip by sintering a powder for the adhesive layer which contains no solid lubricant and which is disposed onto the surface of the metal strip; forming a surface layer by sintering another powder for the surface layer which contains a solid lubricant and which is disposed onto the sintered adhesive layer; and rolling the resulting layers and the metal strip to obtain the composite material.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
145 words
A method of producing a composite sliding material provided with a metal strip, an adhesive layer bonded to the metal strip and surface layer bonded to the adhesive layer, comprising the steps of: preparing the metal strip, a powder for the adhesive layer which powder contains no solid lubricant, and another powder for the surface layer which powder contains a solid lubricant; disposing the powder for the adhesive layer onto the metal strip; sintering the powder for the adhesive layer so that the adhesive layer bonded to the metal strip is formed; disposing said another powder for the surface layer onto the sintered adhesive layer; sintering said another powder disposed on the adhesive layer so that the surface layer bonded to the adhesive layer is formed; and subjecting to a rolling operation the sintered surface layer and the adhesive layer bonded to the metal strip.
Claim 2
Independent Claim
145 words
A method of producing a composite sliding material provided with a metal strip, an adhesive layer bonded to the metal strip and surface layer bonded to the adhesive layer, comprising the steps of: preparing the metal strip, a powder for the adhesive layer which powder contains no solid lubricant, and another powder for the surface layer which powder contains a solid lubricant; disposing the powder for the adhesive layer onto the metal strip; sintering the powder for the adhesive layer so that the adhesive layer bonded to the metal strip is formed; disposing said another powder for the surface layer onto the sintered adhesive layer; sintering said another powder disposed on the adhesive layer so that the surface layer bonded to the adhesive layer is formed; and subjecting to a rolling operation the sintered surface layer and the adhesive layer bonded to the metal strip.
Claim 3
Dependent Claim
22 words
A method as claimed in claim 1, wherein said metal strip is a steel plate or a steel plate plated with copper.
Claim 4
Dependent Claim
37 words
A method as claimed in claim 1, wherein said powder for the adhesive layer is a powder of a copper base alloy or an aluminum base alloy, which has a grain size of 80 to 120 mesh.
Claim 5
Dependent Claim
34 words
A method as claimed in claim 1, wherein said powder for the surface layer is a mixture of a powder of a copper base alloy or an aluminum base alloy and a graphite powder.
Claim 6
Dependent Claim
28 words
A method as claimed in claim 1, wherein said second sintering and said rolling are effected such that said composite has a theoretical density of 75 to 98%.
