BOND COATS FOR TURBINE COMPONENTS AND METHOD OF APPLYING THE SAME

A substrate (12) such as a superalloy turbine component is coated with a basecoat (14) of the type MCrAIY which also contains boron, where the amount of boron in the basecoat is in a concentration gradient where more boron is present near the top (16) than the bottom (20) of the basecoat (14) and bo...
