A method for applying a protective coating to gas turbine engine components using a saturated solution of nickel acetate tetrahydrate, applying a uniform thickness of the coating onto the thermal barrier coating of selected components, and heat treating the coated component in air at a temperature sufficient to form a protective layer of NiO. The saturated NiO solution has sufficient solubility to penetrate into the microscopic cracks of the thermal barrier coating to form a sacrificial mitigation layer of NiO that substantially inhibits the reaction between vanadium pentoxide and yttria-stabilized compounds present in the thermal barrier coating.
