Abstract Methods of honing a surface arc disclosed. The method may include spraying a coating having an initial average bulk porosity onto an engine bore wall and honing the coating to create an intermediate honed surface. The method may then include cleaning the intermediate honed surface and honing the intermediate honed surface with a cutting force of, for example, 110-130 kgf after the cleaning step. This may create a honed surface having an average porosity greater than the initial average bulk porosity. The methods may create a honed surface having a porosity that is more porous than the initially sprayed coating. The increased porosity of the honed surface may allow for increased oil retention in, for example, engine bores. Il est décrit des méthodes de rodage dune surface. La méthode peut comprendre la vaporisation dun revêtement ayant une porosité en masse moyenne initiale sur une paroi dalésage dun moteur et le rodage du revêtement, dans le but de créer une surface rodée intermédiaire. Par la suite, la méthode peut comprendre le nettoyage de la surface rodée intermédiaire et le rodage de la surface rodée intermédiaire avec une force de coupe de 110-130 kgf par exemple, à la suite de létape de nettoyage. Cela peut créer une surface rodée ayant une porosité moyenne plus importante que la porosité en masse moyenne initiale. Les méthodes peuvent créer une surface rodée dont la porosité est plus poreuse que le revêtement vaporisé initialement. La porosité accrue de la surface rodée peut permettre une rétention dhuile accrue dans les alésages de moteur, par exemple.
