ABSTRACT:
A powder mixture for use in a method of repairing a superalloy article includes first and second Ni base superalloy powders. The first powder, characterized by superior hot corrosive resistance along with good oxidation resistance and the substantial absence of melting point depressants selected from Si and B greater than normal impurity levels, is included in the range of 30-70 wt % of the mixture. The second powder has a composition substantially within the same composition range as that of the first powder with the inclusion, by wt, of 0.5-5% B and up to 6% Si.
