ABSTRACT:
A ceramic protective coating system and process for applying the same is provided for superalloy base metal turbine components which are subjected to elevated exhaust temperatures and which exist in a corrosive fluid environment due to the use of fuels which form corrosive compounds upon combustion. The ceramic overcoat consists of at least one protective magnesium titanate of the group MgTiO.sub.3 and Mg.sub.2 TiO.sub.4.
