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镀表面的耐磨表面的涂层的二氧化碳压缩机。 或者，预期丙烷压缩机具有磨损表面涂层。 该涂层是无电镀的，并且可以包括镍和耐磨颗粒，例如氮化硼。 用于压缩机的无电镀表面涂层可提高耐腐蚀和耐磨性，以及压缩机加工含CO2或C3H8制冷剂的抗摩擦性能。 在某些方面，涡旋机具有包含铝的十字联轴器和/或下轴承，并且具有包含设置在一个或多个磨损表面上的氮化镍颗粒的无电表面涂层。 在其他方面，往复式压缩机具有磨损表面，例如涂覆有无电镀镍和氮化硼颗粒层的连杆和/或活塞上。 还提供了制备无电表面涂层的方法。
