Abstract: A vacuum additive manufacturing process enabling obtaining, through a single-step process, the synthesis, controlled densification and shaping of non-oxide materials as well as composite materials containing non-oxide as matrices or reinforcements, in porous as well as fully dense ceramic components, with a tailored nano-micro-macrostructure.

Abstract: 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.
