| 摘要 |
The invention concerns a method for producing a metal sublayer made from platinum on a metal substrate. Characteristically, the method comprises the following steps: a) providing a metal part forming the substrate (100), b) providing an electrolyte bath formed from an ionic liquid medium with one or a plurality of aluminium salts, c) depositing a first layer of a first metal (120) on the substrate (100) in such a way as to obtain a substrate coated with the first metal layer (100+120), d) depositing a second layer of a second metal on the first layer, in such a way as to obtain a substrate coated with the first metal layer and the second metal layer, in which one of the first metal and the second metal is a metal from the platinum group (platinoid) and the other of the first metal and the second metal is aluminium deposited by electrodeposition with said electrolyte bath formed from an ionic liquid medium, and the aluminium layer (130) has a thickness of between 10 and 50 μm. Application to a turbomachine part. |
