Abstract (en)
[origin: WO2015092205A1] The invention relates to a method for manufacturing a part coated with a protective coating, the method comprising the following step: forming a protective coating on the outer surface of a part by micro-arc oxidation treatment, the part comprising a niobium matrix which contains metal-silicide insertions, the current passing through the part being monitored during the micro-arc oxidation treatment in order to subject the part to a series of current cycles, the ratio (amount of positive charge applied to the part) / (amount of negative charge applied to the part) being, for each current cycle, 0.80 to 1.6.
