  • Patent number: 9650585
    Abstract: A solid lubricant magnetron sputtering physical vapor deposition (MS PVD) coating can be used e.g. in automotive, aircraft and space industries for increasing lifetime of moving parts such as bearings, chains, pistons and joints that experience sliding or rolling friction. A nanocomposite solid lubricant coating contains a carbon matrix with copper grains and at least one of Ti, Zr, Hf, and V, in bulk proportions, at. %: carbon ?5-35; copper 50-90; additional metal ?5-15. The carbon matrix with copper grains is reinforced with interlayers of the additional metal. The thickness of each layer of the carbon matrix with copper grains is in the range between 30 and 150 nanometers and the thickness of each interlayer of the additional metal is in the range between 5 and 20 nanometers. The hardness of said coating is in the range between 200 and 1000 HV.
