Slurry Coatings with Low Cr6+ Content: Aluminum Overlay Coatings for Compressor Parts and Aluminide Coatings for Turbine Components.

摘要

Inorganic slurry coating based on a ceramic binder which contains aluminum or aluminum and silicon are very effective coatings in engines and gas turbines. All of these coatings contain much chromic acid, causing health problems when applied by the usual spraying technique. A new generation of slurry coatings with minimized Cr~6+ (<0.5
