Abstract: Functional performance depends largely on the surface characteristics of critical components. This paper describes the design of dimpled engineering surfaces and the fabrication of micro-patterns on steel samples. The designed engineering surfaces are analysed and evaluated in terms of their mixed EHL film thicknesses and pressure distributions in the elliptical Hertzian contact zone.

Keywords: surface engineering; surface structuring; surfaces; mixed EHL contact; film thickness; dimpled surfaces; finishing technology.
