发明名称 Piston for an internal combustion engine
摘要 A piston for an internal combustion engine has at least two hub bores for holding a piston pin. The hub bores are formed with a cylindrical inner contour and are provided with a coating comprising a resin with solid lubricant particles embedded therein. The coating forms at least one geometric deviation from the cylindrical inner contour of the hub bores. A method for producing a piston of the type, includes producing bores with a cylindrical inner contour and applying a coating medium comprising a resin with solid lubricant particles embedded therein to the inner faces of the bores by a coating tool, such that the resulting coating forms at least one geometric deviation from the cylindrical inner contour of the hub bores.
