<p>Method for forming a protective layer on a metallic turbine substrate, comprising the steps of: preparing an aqueous solution comprising a first component comprising a soluble salt or alkoxide; dissolving in the solution a second component based on an organic substance comprising a carbonyl group or an amine group; bringing the solution into contact with the metallic substrate; and heating the metallic substrate to a temperature in the range from 300
C to 800
C to form a layer of oxide on the metallic substrate. The first component is preferably a nitrate. The second component is preferably selected from the group consisting of urea, amino-acids, organic acids, hydrazine and its derivatives, azine and its derivatives, amines and mixtures of these.</p> |
