Nickel aluminide refers to either of two widely used intermetallic compounds, Ni 3 Al or NiAl, but the term is sometimes used to refer to any nickel–aluminium alloy. These alloys are widely used because of their high strength even at high temperature, low density, corrosion resistance, and ease of production. [ 1 ]
Nickel aluminide will ignite on heating to at least 250 °C in rate of at least 200 °C/min. Slower heating will anneal the material, causing loss of its pyrotechnic properties. For electrical initiation, a momentary contact at 10A/5V is sufficient; for ohmic contact, 120-150 amperes is needed for a 15 micrometer diameter contact, and 250-300 A ...
The five major types of bond coats are: the aluminides, the platinum-aluminides, MCrAlY, cobalt-cermets, and nickel-chromium. For aluminide bond coatings, the coating's final composition and structure depends on the substrate composition. Aluminides lack ductility below 750 °C, and exhibit limited thermomechanical fatigue strength.
Aluminides are intermetallic compounds of aluminium. [1] Since aluminium is near the nonmetals on the periodic table, it can bond with metals differently than other metals. The properties of an aluminide are between those of a metal alloy and those of an ionic compound. Aluminides are used as bond coats in thermal barrier coating systems. [2]
Nickel–aluminium alloy may refer to: Y alloy, series of aluminium alloys with addition of nickel developed during WWI; Hiduminium, series of aluminium alloys with addition of nickel developed before WWII; Nickel aluminide, alloys containing much more nickel than the previous ones.
