MACHINE PART BELONGING TO A SLIDING PAIR AND METHOD FOR THE PRODUCTION THEREOF

摘要

The invention relates to a machine part (4) belonging to a sliding pair, having in at least the region of the side facing the machine part acting together therewith a wear-resistant structure (6) comprising relatively hard particles received in a metal matrix and having a rough and uneven surface, the production effort being reduced and good run-in behavior being achieved in that a run-in overlay (7) is applied to the wear-resistant structure (6) to smooth out the unevenness and roughness thereof, made of a run-in material suitable for wear during a run-in process, the material being different from the material of the wear-resistant structure (6) beneath it and being metallurgically bonded thereto, and being softer than the wear-resistant structure (6) and at most equally as wear-resistant as the sliding surface of the respectively opposite machine part.
