Nickel aluMinuM

Использование

Nickel aluminum is used in strengthening constituent in high-temperature nickel-base superalloys, coating blades in gas turbines and jet engines.

Промышленное использование

Nickel aluminide (NiAl) is available commercially in powder form in various mesh sizes from granular material to an average particle size of a few micrometers. Thermal shock resistance is quite good.
Nickel aluminide can be formed by hot pressing or by cold pressing and sintering, but the former method produces by far the best results. Excellent oxidation resistance and fairly good strength make this material of interest for turbine blading or other combustion chamber applications. It has impact resistance that is better than most ceramics, intermetallic compounds, and some cermets. NiAl is also resistant to attack by molten glass and red and white fuming nitric acid, which suggests possible uses in the glass-processing industry or in some high-temperature chemical processes.
