Mechanical Seals With Sliding Surface Texture – Model Fluid Flow and Some Aspects of the Laser Forming of the Texture

Abstract

Abstract Energy losses resulting from friction between contact surfaces in an internal combustion engine have been studied intensively by a considerable number of tribologists. Still, the automotive industry needs further improvements to reduce friction-related energy losses in engines and drive systems. This problem can be solved by applying porous surfaces generated, for example, by laser surface texturing.
