ABSTRACT:
A composition comprising a particulate corrosion resistant component, and a glass-forming binder component. The particulate corrosion resistant component comprises from 0 to about 95% alumina particulates, and from about 5 to 100% corrosion resistant non-alumina particulates having a CTE greater than that of the alumina particulates. Also disclosed is an article comprising a turbine component comprising a metal substrate and a corrosion resistant coating having thickness up to about 10 mils (254 microns) overlaying the metal substrate. At least the layer of this coating adjacent to the metal substrate comprises a glass-forming binder component and the particulate corrosion resistant component adhered to the glass-forming binder component. Further disclosed is a method comprising the following steps: (a) providing a turbine component comprising the metal substrate; (b) depositing on the metal substrate a corrosion resistant coating composition; and (c) curing the deposited corrosion resistant coating composition to form at least one layer of a corrosion resistant coating having a thickness up to about 10 mils (254 microns).
