A high velocity oxygen fuel thermal spray powder comprising a superalloy having the formula MCrAlY-X, wherein M is at least one metal taken from the group consisting of nickel, cobalt, and iron; X is at least one reactive element taken from the group consisting of hafnium, rhenium, lanthanum, and tantalum; and yttrium is present in levels greater than 1% by weight of the total composition and up to about 6% by weight of the total composition. In addition, the powder may be blended with an agglomeration of M'CrAlY and a ceramic, wherein M' is at least one metal taken from the group consisting of nickel, cobalt, and iron. The invention offers improved high temperature oxidation, corrosion and creep resistance.
