Abstract
Official abstract text for this publication.
A method for forming a protective coating containing aluminum and zirconium on the surface of a metal part. The part is put into contact with a cement made of aluminum alloy, at a treatment temperature, with an atmosphere containing an active gas which reacts with the cement to form a gaseous aluminum halide, which decomposes in contact with the part depositing metallic aluminum thereon, the active gas containing ZrOCl 2 that decomposes in contact with the part depositing Zr metal thereon, and being formed by vaporizing granules of ZrOCl 2 that are solid at ambient temperature. The part, the cement, and ZrOCl 2 granules are then progressively heated together in a chamber from ambient temperature to the treatment temperature with a plateau at 400° C.±200° C.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for forming a protective coating containing aluminium and zirconium on a surface of a metal part, the method comprising: placing the part, a cement made of aluminium alloy, and granules of ZrOCl 2 in a chamber; applying a treatment temperature to the chamber to form an atmosphere comprising an active gas which reacts with the cement to form a gaseous aluminium halide, which decomposes in contact with the part depositing metallic aluminium t…
