Use of experimental designs to evaluate formation of aluminide and platinum aluminide coatings

Surface and Coatings Technology, 1998
Abstract Aluminide and platinum-modified aluminide coatings are widely used for protecting nickel and cobalt-based superalloy gas turbine engine components from oxidation and corrosion. Conventional methods for producing these coatings include pack cementation, `above-the-pack', and CVD aluminization processes.

The formation of aluminides in intermetallic nickel aluminide-based nanocomposites

Journal of Alloys and Compounds, 2005
Abstract Metal matrix composites based on the intermetallic alloy Ni 3 Al and alumina were fabricated using powder metallurgy technique. Nanosize alumina as dispersed phase was mixed with Ni and Al powder in a planetary ball mill for 4 h at 350 rpm to achieve a small mechanical alloying effect.

Oxidation of Aluminides

Materials Science Forum, 1997
L'oxydation de NiAl, FeAl, et TiAl ainsi que celle d'alliages de composes intermetalliques ont ete largement etudiees dans les dernieres annees. A haute temperature, on observe la formation selective de AlO 3 dans NiAl et FeAl, tandis qu'a plus basse temperature, on trouve des modifications metastables.

The addition of zirconium to aluminide coatings: The effect of the aluminide growth mode

Surface and Coatings Technology, 2019
Abstract Alumina-former coatings such as nickel aluminides have been the essential approach to combating the aggressive service environment of gas turbine hot section components. The positive effects of zirconium on the cyclic oxidation lifetime of aluminide coatings have been reported.

Advanced grinding of titanium aluminides

International Journal of Manufacturing Technology and Management, 2007
In aerospace industry, titanium alloys are used for turbine components. The material properties and the specific grinding kinematics enhance the risk of thermally damaging these components. Speed stroke grinding represents an alternative to common grinding strategies while reducing machining time and production cost but simultaneously enhancing the ...
