Minor Element Additions to Single Crystals For Improved Oxidation Resistance Abstract The additions of minor additions of hafnium and silicon and mixtures thereof to nickel base superalloy single crystal articles provide significantly improved oxidation resistance. The oxidation resistance is im- proved both for the case of uncoated articles and in the case where a protective coating such as for example, a MCrAlY coating is present. For example the addition of .1% hafnium is observed to improve the oxidation re- sistance by a factor of 4 at 2100°F and a similar ad- dition improved the coated oxidation resistance by a factor of about 2.5 at 2150°F.
