Phase Determination in Flame-sprayed ‘Nickel Aluminide’ Coating

Nature volume 209, pages 706–707 (1966)Cite this article

Abstract

‘NICKEL Aluminide’ coatings (‘Metco 404’, Meteo Inc., Westbury, New York, patents pending on the material and process) are manufactured by introducing aluminium particles jacketed with nickel into the flame of a spray gun. This powder then undergoes an exothermic reaction, and as a result of this heat evolution these coatings are self-bonding to many other materials. The producers claim1,2 that the coating, flame-sprayed according to their instructions, consists mainly of NiAl, Ni3Al and mixtures of these two. They claim further that they also have found some ‘black oxide’ of aluminium in the pores and voids of the coating.
