<p>PURPOSE: A piston ring for a vehicle with multiple coating layers is provided to obtain heat resistance over 500 deg., abrasion resistance, and a low friction property by coating a Cr or Ti buffer layer, a CrN or Ti(C)N intermediate layer, and TiAlCN layer on a base member of the piston ring. CONSTITUTION: A piston ring for a vehicle with multiple coating layers comprises a Cr or Ti buffer layer, a CrN or Ti(C)N intermediate layer, a TiAlN/CrN nano multilayer, and a TiAlCn layer. The Cr or Ti buffer layer is coated on a base member of the piston ring. The CrN or Ti(C)N intermediate layer is coated on the Cr or Ti buffer layer. The TiAlN/CrN nano multilayer is coated on the CrN or Ti(C)N intermediate layer. The TiAlCn layer is coated on the TiAlN/CrN nano multilayer as the outermost layer. [Reference numerals] (AA) Base material; (BB) Total thickness of a coating layer: 0.31-25.5um</p> |
