Verfahren zur Herstellung eines Überzuges auf der Basis von MCrAlY mit feinverteilten Oxiden

摘要

A thermal spray process for producing a MCrAlY-based coating wherein M is selected from the group consisting of iron, cobalt, nickel and mixtures thereof and wherein the oxygen in the fuel-oxidant mixture of the thermal spray process converts a substantial portion of the yttrium component to Y2O3, a minor portion of the aluminum component to Al2O3, and the Y2O3 and Al2O3 are present in an amount of less than 15 volume percent of the coating.
