Abstract
The utility model discloses a piston-ring I-shaped oil control ring with a superhard multi-arc ion plating layer at the excircle. The I-shaped oil control ring adopts a piece of martensite stainless steel or a piece of spheroidal graphite cast iron as the base body. The superhard multi-arc ion plating layer containing CrN, TiN, AlN or ZrN is formed on an excircle surface. Such a piston-ring I-shaped oil control ring has the characteristics of good friction pair matching, high wear resistance and long service lifetime.
Description
Technical field
The utility model relates to a kind of improvement of piston ring I shape oil control ring, and it is applicable to the automobile and the motorcycle IC engine of various models.
Background technique
Along with developing rapidly of automotive industry, also more and more stricter to the performance requirement of its component, impel relevant technology and technology constantly improve, perfect; Piston ring is a kind of relatively more crucial component, therefore many correlation technique improvement projects occurred, for example; Chinese patent CN20062007124.2 number about " chrome plated piston ring comprehensively "; It is on the basis of the periphery chromium plating of piston ring, to chromium plating respectively on the inner headed face of piston ring and the bi-side, can increase the hardness of piston ring like this; Improve its wear resistance, but are still waiting further raising, perfect in its performance and working life.
Summary of the invention
The task of the utility model is the piston ring I shape oil control ring that a kind of unique texture will be provided, and its wear-resisting property significantly improves, long service life, and the friction pair matching further improves.
The task of the utility model is to accomplish as follows; It is to select for use Martensitic Stain Less Steel or spheroidal graphite cast iron to process the matrix of I shape oil control ring; Use the processing of vacuum arc deposition technology at the external circular surfaces of I shape oil control ring, on the periphery of piston ring I shape oil control ring, produce a kind of CrN or TiN, AlN, superhard multi-arc ion coating construction layer of ZrN of containing.The piston ring I shape oil control ring of the superhard multi-arc ion coating layer of this cylindrical, wear resistance is strong, long service life, the friction pair matching is good, and also prolong relatively cylinder sleeve working life of its coupling, and constant product quality, reliable, its performance have had and have significantly improved.
