Abstract
Official abstract text for this publication.
A method for depositing an aluminizing coating onto a substrate. The method includes: (a) depositing a layer, containing platinum and at least 35% of nickel, onto a surface of the substrate; and (b) depositing an aluminum coating onto the layer.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for depositing an aluminizing coating on a substrate, comprising: (a) depositing a first layer containing platinum on a surface of the substrate by electrolysis using a first electrolytic bath containing platinum salts, then depositing a second layer containing nickel on the first layer by electrolysis using a second electrolytic bath containing nickel salts, the second layer is made up of nearly 100% nickel, and the depositing of the first layer and the depositing of the second layer being performed consecutively in a same facility at ambient pressure; and (b) depositing an aluminum coating directly on the second layer. 2. The method according to claim 1 , wherein the substrate is a superalloy. 3. The method according to claim 2 , wherein the superalloy is a nickel-based superalloy. 4. The method according to claim 1 , wherein before the deposition of the first layer and the second layer in (a), the surface of the substrate is prepared. 5. The method according to claim 1 , wherein no diffusion treatment of the first layer is done. 6. The method according to claim 1 , wherein the aluminum coating is deposited by chemical vapor deposition. 7. The method according to claim 1 , wherein the first layer consists essentially of platinum. 8. The method according to claim 1 , wherein the second layer does not comprise platinum. 9. The method according to claim 1 , wherein the depositing the aluminum coating consists essentially of depositing aluminum atoms. 10. The method according to claim 1 , wherein the second layer is made up of 100% nickel.
