ABSTRACT:
A method for coating turbomachinery having a metal surface to prevent fouling, the steps of the method being applying to the surface a first slurry containing an acidic aqueous medium containing galvanically active material and phosphate ions, thereby forming a galvanically sacrificial first layer, curing the first layer, applying to the cured first layer an aqueous non-conductive second slurry containing inorganic phosphate or silicate ions, thereby forming a non-conductive second layer, curing the second layer, applying to the cured second layer a liquid sealer composition containing a thermally stable organic polymer and fluorocarbon, thereby forming a top layer, and curing the top layer.
