PVD-coated high-performance bearings

Abstract

In the course of the ongoing further development of diesel engines, the loads have increased so much that three-metal bearings have reached their limits as con rod bearings. The electroplated sliding layer shows signs of fatigue in the form of hen track patterns and erosion. In order to avoid that, the bearing metal AlSn20Cu, which has also been in successful use for years, was therefore the obvious choice.
