Abstract
A method for preventing corrosion in a component of a turbo-machine having a metal substrate made of carbon steel, low alloy steel and stainless steel includes: a first deposition step of depositing a first metallic layer on the substrate by electroplating; a second deposition step of depositing at least a second layer of a nickel alloy on the first layer by electroless plating; at least one thermal treatment step after the deposition steps, said thermal treatment being applied at a temperature and for a time depending on the overall thickness of the layers, the value of said temperature being directly proportional to the thickness, the value of said time being inversely proportional to the temperature.
