Abstract
A coating for a portion of the flowpath of a diffuser of a centrifugal compressor. The coating covers a portion of the diffuser against which flows high velocity air from the compressor blades. The coating is a smooth, tenacious, heat-resistant powder paint that reduces the aerodynamic drag of the diffuser walls on the high velocity air thus increasing the efficiency of the compressor.
