Abstract
Lubrication deficiencies related to the use of lubricants in HFC refrigeration compressors can be mitigated by providing a diamond-like-carbon coating on a member subject to wear due to lubrication deficiencies. Specifically, the tip of the vane of a rotary compressor is coated with a diamond-like-carbon coating made up of alternating layers of tungsten carbide and a lubricious material 0.5 to 5.0 microns thick.
