Method of honing high-porosity cylinder liners
Abstract
Methods of honing a surface are 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.
