Abstract

A method for the production of a metal bearing layer (L) on a cylinder barrel (3) of a hydrostatic displacement machine (1), in particular of an axial piston machine, in which the metal bearing layer (L) is produced from a sintering powder in a sintering process. In a first production step, a dimensionally stable green compact (31) is produced from a sintering powder by a cold pressing process. In a second subsequent production step, the green compact (31) produced by the cold pressing process is sintered onto the cylinder barrel (3) in a sintering process.
