A method for forming a modified platinum aluminide coating on a turbine engine component surface includes the step of forming a platinum layer on the turbine engine component surface. A bath is then prepared, including a mixture of a primary alcohol and a tertiary alcohol, and an electrolyte including an yttrium salt. Then, yttrium from the yttrium salt is electrodeposited onto the platinum layer. The component is heated to diffuse the yttrium into the platinum layer to form a modified platinum layer. Aluminum is then deposited onto the modified platinum layer, and the component is heated to diffuse the aluminum into the modified platinum layer to form a modified platinum aluminide layer. |
