Abstract
A substrate (12) such as a superalloy turbine component is coated with a basecoat (14) of the type MCrAlY 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 boron is present in an average amount of over 0.50 wt. % throughout the basecoat cross-section (14) of the composite (10).
