Method (100) for preventing corrosion in a component (1) of a turbo-machine having a metal substrate (5) made of carbon steel, low alloy steel and stainless steel includes: -a first deposition step (110) of depositing a first metallic layer (2a) on the substrate (5) by electroplating; -a second deposition step (120) of depositing at least a second layer (2b) of a nickel alloy on the first layer (2a) by electroless plating; -at least one thermal treatment (140) step after the deposition steps (110, 120), said thermal treatment (140) being applied at a temperature (T) and for a time (t) depending on the overall thickness of the layers (2a, 2b), the value of said temperature (T) being directly proportional to the thickness, the value of said time (t) being inversely proportional to the temperature (T). |
