摘要:
The invention relates to a method for depositing an anti-corrosion coating on at least some of the surfaces of a metal substrate having at least one cavity with a diameter of e mm mm /10.
摘要:
A method for producing an element comprising a multilayer architecture of which the layers comprise primary channels on the upper faces thereof, said method comprising the following successive steps: (a) producing secondary channels (2) on the lower faces of each layer, each secondary channel (2) being intended to face a primary channel of the adjacent lower layer within the architecture, (b) depositing a coating protecting against oxidation at a temperature of between 500 and 1000°C and against corrosion on all of the lower and upper surfaces of the layers, (c) mechanically sanding or etching the surfaces that are to be assembled, and (d) assembling the various layers by stacking in such a way that each secondary channel (2) of a lower face of an upper layer is facing and is centred on a primary channel (1) of the adjacent lower layer, the width of each secondary channel (2) being greater than the width of the primary channel (1) that it is facing within the architecture.
摘要:
The invention relates to a method for depositing a coating on a substrate having at least one cavity, comprising: a step of mixing ground powders of an activating agent and a powder of the metal or alloy to be deposited on the substrate, ground in step (a) and a liquid such as to form a suspension; and a step of applying the suspension on part of the substrate to be coated.
摘要:
The invention relates to the use of a cement in a method for pack-cementation deposition on a substrate containing cavities having a minimum equivalent diameter e cm , characterised in that the cement is formed by spherical particles each having a diameter d such that d ≤ e cm /10.
