Structuring of Metallic 3D Surfaces by the Etching Process: Microstructuring Reduces Friction Losses Between Curved Surfaces by Improving Tribological Properties
This process, presented at the PCMI Conference
in Atlanta in September 2005, describes a photochemical
method used to create microstructures
on curved metallic surfaces (for instance, on the
inner walls of cylinder liners). Such structures
act as oil-retaining depressions to reduce friction
and improve the tribological properties of
components involved in this process. Reduced
friction offers advantages relative to oil and fuel
consumption, reduced abrasion, and improved
lifetime of parts.
