Patent

CA 2461406

This relates to an improvement to the process of aluminization or activated cementation in which a donor cement containing the aluminum is attacked at high temperature and in a neutral or reducing atmosphere by a gaseous ammonium halide to form a gaseous aluminium halide which decomposes on contact with a nickel-based substrate depositing aluminium metal thereon. According to the invention the aluminum halide is at least partly replaced by a zirconium halide leading to the inclusion of zirconium in the deposit. Improvement in the protection of the hot parts of aircraft engines made of nickel-based superalloy.

Il s'agit d'un perfectionnement du procédé d'aluminisation, ou cémentation activée, dans lequel un cément donneur contenant de l'aluminium est attaqué, à température élevée et en atmosphère neutre ou réductrice, par un halogénure d'ammonium gazeux pour former un halogénure d'aluminium gazeux, lequel se décompose au contact d'un substrat à base de nickel en y déposant de l'aluminium métallique. Selon l'invention, l'halogénure d'ammonium est remplacé au moins en partie par un halogénure de zirconium, conduisant à l'inclusion de zirconium dans le dépôt. Amélioration de la protection des pièces chaudes de moteurs d'avions en superalliage à base de nickel.
