Method for roughening and coating a surface

Номер: US20130284140A1
Принадлежит: FORD GLOBAL TECHNOLOGIES LLC

A method for roughening and thermally coating a surface, in particular a cylinder running surface of an internal combustion engine, the roughening being the preparation of the surface for the thermal coating of the surface with a coating. The method is characterized in that different roughening profiles are introduced into the surface during the roughening and the coating has different properties distributed over the surface. This allows the coating or spraying process during the later thermal coating to be carried out with substantially constant spraying parameters. The different properties of the coating, such as hardness, porosity, machinability, chemical composition, oxidation and adhesion, are then obtained just on the basis of the differently roughened surface.
