Abstract

The invention provides components for compressors having electroless coatings on wear surfaces. 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.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Invention Application No. 14 / 527,484, filed October 29, 2014 and also claims the benefit of US Provisional Application No. 61 / 897,383, filed October 30, 2013. The entire disclosure of the above application is incorporated herein by reference. technical field [0003] The present disclosure generally relates to compressors, including scroll compressors and reciprocating compressors. More specifically, the present disclosure relates to carbon dioxide (CO 2 ) refrigerant or propane (C 3 h 8 ) compressors with wear-resistant surfaces for use with refrigerants. Background technique [0004] This section provides background information related to the present disclosure which is not necessarily prior art. [0005] Various refrigerants have been used in refrigeration systems that include compressors, such as scroll compressors or reciprocating compressors. For example, halogenated h...
