US Patent 9605677 Anti-wear coatings for scroll compressor wear surfaces

Anti-wear surface coatings and methods for making them are provided. Such anti-wear surface coatings are particularly suitable for use in a compressor, such as a scroll compressor. A precursor powder material can be applied via spraying to a wear surface of a metal component of the scroll compressor. The precursor powder material comprises a powderized thermoplastic polymer (e.g., PEEK), a first lubricant particle (e.g., molybdenum disulfide (MoS2)) and a second lubricant particle (e.g., polytetrafluoroethylene (PTFE)). Then the applied precursor powder material is heated to form a substantially uniform coating covering the underlying metal component. The substantially uniform coating may have a thickness of less than or equal to about 0.005 inches (about 127 μm).
