Production of tribological surfaces on a workpiece used in production of cylinder faces comprises finely processing a surface of workpiece, removing surface layer, finely grinding surface and obtaining hard material phases

摘要

Production of tribological surfaces on workpiece comprises: forming workpiece made from material consisting of metal matrix with embedded hard material phases; finely processing one surface of workpiece; removing surface layer; finely grinding surface modified by hard material phases; and obtaining hard material phases in plateaus of same height. During the formation of the tribological surfaces, the hard material phases are exposed on the periphery whilst the metal matrix is removed. An Independent claim is also included for a device for carrying out the process. Preferred Features: The hard material phases are exposed by honing to a depth of 0.15-0.3 mu m using a honing strip containing grinding particles made from fused alumina or cast steel with a matrix made from a chemically foamed epoxy resin.
