Abstract:
Carbon dioxide compressors having one or more coatings with wear surfaces having electroless surface coatings are provided. Alternatively, propane compressors are contemplated having wear surface coatings. The coating is electrolessly applied and may comprise nickel and wear resistant particles, such as boron nitride. The electroless surface coatings for use with compressor machines improve corrosion and wear resistance, as well as anti-friction properties for compressors processing CO2 or C3H8 containing refrigerants. In certain aspects, a scroll machine has an Oldham coupling and/or lower bearing comprising aluminum and has an electroless surface coating comprising nickel boron nitride particles disposed on one or more wear surfaces. In other aspects, a reciprocating compressor has a wear surface, such as on a connecting rod and/or piston coated with an electrolessly applied nickel and boron nitride particle layer. Methods for making the electroless surface coatings are also provided.
