Abstract
A method, HVACR system, and positive displacement compressor that includes a compressor housing and a rotating component and at least one second component. Each of the rotating component and the at least one second component have a contacting surface that define a meshing location between the rotating component and the at least one second component to form a compression chamber. Additionally, a coating layer is provided on the contacting surface of at least one of the rotating component or the at least one second component, in which the coating layer includes at least a first applied layer and a second applied layer. The first layer and the second layer are separate layers and both the first layer and the second layer include a conforming material, in which the conforming material in the first applied layer has a different particle size than the conforming material in the second applied layer.
