Verfahren und Vorrichtung zum Herstellen von verschleißfesten, tribologischen Zylinderlaufflächen

摘要

The invention relates to a method and a device for producing wear-resistant tribological cylinder running surfaces (16) for pistons running in the cylinders (20) of a crankcase of an internal combustion engine, comprising a laser (10) and a powder feeding device (12) that guides a jet (13) of a powdery material through a laser beam (22) of the laser (10). The powder feeding device (12) is disposed in such a way that it traverses the laser (10), wherein a beam deflection device (24) for the laser beam (22) is disposed in such a way that it deflects the laser beam (22) to a point (14) where the beam (13) coincides with the powdery material on the cylinder running surface (16).
