Abstract:

Tensile tests of the bonds formed by sintering together preoxidized metal surfaces indicate that the rate of oxide bonding is determined principally by the rate of metal ion migration through the oxide. For the nickel-base alloys, Inconel X, Inconel 600, Udimet 500, and Udimet 700, for which the oxide is essentially Cr2O3, the strengths of the bonds are all of the same magnitude, and secondary alloying additives have only a slight effect. The rate of bonding increases with temperature and decreases as the thickness of the scale formed by preoxidation is increased.
