OXIDATION RESISTANT PROTECTIVE COATING SYSTEM FOR GAS TURBINE COMPONENTS, AND PROCESS FOR PREPARATION OF COATED ABSTRACT OF THE DISCLOSURE A coating for protecting the surfaces of gas turbine components such as single crystal turbine blades and vanes, wherein the coating has a composi- tion (in weight percent) consisting essentially of chromium, 15-35; aluminum, 8-20; tantalum, 0-10; tantalum plus niobium, 0-10; silicon, 0.1-1.5; haf- nium, 0.1-1.5; yttrium, 0-1; cobalt, 0-10; and nickel, balance totalling 100 percent. A preferred coating; which is particularly desirable for use with single- crystal turbine blades and vanes, has a composition consisting essentially of chromium, 17-23; aluminum, 10-13; tantalum plus niobium, 3-8; silicon, 0.1-1.5; hafnium, 0.1-1.5; yttrium, 0-0.8; cobalt, O-trace; and nickel, balance totalling 100 percent. A process for preparing the coated component is also described.
