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.

Abstract translation: 提供具有一个或多个具有无电表面涂层的磨损表面的涂层的二氧化碳压缩机。 或者，丙烷压缩机被认为具有磨损表面涂层。 该涂层被无电地施加并且可以包含镍和耐磨粒子，例如氮化硼。 用于压缩机设备的化学表面涂层改善了耐腐蚀性和耐磨性，以及处理含有制冷剂的CO2或C3H8的压缩机的抗摩擦性能。 在某些方面，涡旋机器具有包括铝的十字滑块联轴器和/或下轴承，并且具有包含布置在一个或多个磨损表面上的镍氮化硼颗粒的无电表面涂层。 在其它方面，往复式压缩机具有磨损表面，例如在涂覆有无电施加的镍和氮化硼颗粒层的连接杆和/或活塞上。 还提供了用于制造无电表面涂层的方法。
