Abstract (en)

It is disclosed a method of depositing a bond MCrAIY-coating to a surface of an article for increasing the roughness for enhanced TBC adhesion. First, an inner layer on top of the surface of the article consisting of gamma / gamma '-MCrAlY is deposited using powder in the size range from 5 to 65 mu m. Second, an outer bond coating layer on top of the inner layer consisting of beta -NiAl or gamma / beta -MCrAlY or gamma / gamma '-MCrAlY is deposited using powder in the size range from 30 to 125 mu m.
