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...

description 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 boron is present in an average amount of over 0.50 wt.% throughout the basecoat cross-section (14) of the composite (10). Un substrat (12), tel qu'un composant de turbine en superalliage est enduit d'une couche de base (14) du type MCrAIY qui contient également du bore, la quantité de bore dans la couche de base correspondant à un gradient de concentration selon lequel le bore est présent en quantité plus importante à proximité du sommet (16) que dans la partie inférieure (20) de la couche de base (14) et le bore est présent en quantité moyenne supérieure à 0,50 % en poids sur la section (14) de la couche de base, du composite (10).
