Verfahren zur Steigerung der Randschichtfestigkeit an Oberflaechen von aus sproedharten Werkstoffen gefertigten Werkstuecken

The method comprises bringing the workpiece surface within narrowly bounded regions into contact with a tool which plastically deforms such surface regions and produces compressive near-surface stresses within the workpiece. USE - Used in bearing technology. ADVANTAGE - The method is simple and cost-effective method, and can be used to the strength of ceramic components such as, for example, bearing bushes in pumps, stirring units etc..
