METHOD FOR IMPROVING THE EROSION RESISTANCE OF ENGINE COMPONENTS

摘要

The present invention relates to a coating system for engine components which exhibits improved erosion resistance and a method for forming the coating system on the engine components. The coating system is formed by a fluororelastomeric material which is co-cured or bonded with the organic matrix material forming the engine component. The coating system is applied to the engine component by overlaying a thin sheet of the fluoroelastomeric material in a cured or uncured state over a preform of the engine component, placing the preform and the fluoroelastomeric material in a molding device, and heating the engine component preform and the fluoroelastomeric material to a temperature at or above about 340 DEG F to effect co-curing and/or bonding.
