  • Method of manufacturing coated piston ring
    Patent number: 5713129
    Abstract: A coated piston ring and method of manufacture for internal combustion engines and compressors. The piston ring having a outer peripheral surface that is coated with a thin substantially final finish spray wear resistant coating for contacting the cylinder wall. The material coating is deposited by high velocity oxygen fuel spray apparatus and a sharp bottom edge is lapped thereon for contacting the cylinder wall of the apparatus. The method of manufacturing comprising rotating a plurality of piston rings about a central axis while the high velocity oxygen fuel gun sprays molten coating material thereon. The molten coating material forming a mechanical interlock with the ring blank to produce a substantially final finish spray coating on the periphery of the piston rings.
