The invention relates to a multilayer multi-element composite hard PVD coating with low friction coefficient on the surface of a piston ring, a piston ring and a preparation process. The present invention employs vacuum multi-arc ion plating vapor deposition process, which uses multiple multi-arc ion sources, in the combination of equipping with different single metal target material and multi-element target material to deposit multilayer multi-element composite hard PVD coating with low friction coefficient on the surface of a steel or cast iron piston ring. The coating consists of five layers with the total thickness of up to 60 μm. The coating has high adhesion with the surface of piston ring, high hardness, low friction coefficient and good abrasion resistance. By controlling the adding amount of additive elements Al, Mo, W, B, Si and Ti, the friction coefficient of the coating can be further reduced 5 to 20% compared with that of a single TiN or CrN deposited layer.

摘要:
To apply a thermal barrier coating (10), a plasma jet (5) is generated by a plasma torch in a work chamber (2) and is directed to the surface of a substrate (3) introduced into the work chamber, and a ceramic coating material is applied to the substrate surface by means of PS-PVD, wherein the coating material is injected into the plasma jet as a powder and is partly or completely vaporized there. On applying the thermal barrier coating, in a first workstep the feed rate of the injected powder is set so that a large part of the injected powder vaporizes, wherein the coating material condenses from the vapor phase on the substrate surface and forms mixed phases with the material of the substrate surface. In a second workstep, the feed rate of the injected powder it increased by at least a factor of 5, whereby the portion of the powder which vaporizes is reduced and the coating material is deposited in the form of elongate columns which form an anisotropic microstructure and which are aligned substantially perpendicular to the substrate surface.
