Abstract
Abstract A sliding member having threads of solid lubricant embedded in a densely distributed state is obtained by drilling or casting a multiplicity of parallel holes into a metal blank through one terminal face thereof, filling the holes with a solid lubricant and elongating the lubricant-containing metal block in the direction of said holes by means of a rolling machine.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
89 words
A method for the manufacture of an abrasion-resistant sliding member consisting essentially of the steps of forming a multiplicity of parallel holes into a metal blank through one terminal face thereof, filling the holes with a solid lubricant, scaling the terminal face so that the solid lubricant cannot substantially enude out during the subsequent elongation, and elongating the solid lubricant-containing metal block in the direction of the sand holes for thereby causing the cross section of the metal to contract simultaneously with the cross section of the lubricant-filled holes.
Claim 2
Independent Claim

Claim 3
Dependent Claim
29 words
A method according to claim 1, wherein the material of the metal blank is one member selected from the group consisting of copper, nickel, nickel alloy and stainless steel.
