  • Process for repairing a cylinder running surface by means of plasma spraying processes
    Patent number: 8877285
    Abstract: A method of repairing an inner surface of a cylinder liner housed in an engine block. Material is removed from the inner surface to produce a reduced-thickness region, the reduced-thickness region extending axially relative to the cylinder and stopping short of an end of the liner to leave a region of original diameter between the reduced thickness region and the end of the liner. The surface the reduced-thickness region is then roughened, for example by hammer brushing. A plasma coating is applied to the reduced-thickness region and to at least a portion of the region of original diameter. The coating is then finish-machined to produce a uniform internal diameter equal to an original internal diameter of the region of original diameter prior to the application of the coating.
