Title (EN) NOVEL MASK FORMULATION TO PREVENT ALUMINIZING ONTO THE PRE-EXISTING CHROMIDE COATING
(FR) NOUVELLE FORMULATION DE MASQUE POUR EMPÊCHER L'ALUMINISATION SUR UN REVÊTEMENT DE CHROMURE PRÉ-EXISTANT
Abstract:
(EN) A novel dual layer mask formulation is provided. In particular, the mask has a unique composition that protects the integrity of an underlying chromide coating, prevents chromium depletion from the chromide coating and prevents a subsequent aluminide coating from being deposited thereon.
(FR) L'invention concerne une nouvelle formulation de masque bicouche. En particulier, le masque possède une composition unique qui protège l'intégrité d'un revêtement de chromure sous-jacent, empêche l'appauvrissement en chrome dans le revêtement de chromure et empêche le dépôt d'un revêtement d'aluminure ultérieur sur celui-ci.
