    摘要： A silicon carbide-based thermal spray powder contains at least one boride chosen from zirconium boride, titanium boride and hafnium boride. The powder is prepared by mixing and aggregation of powders containing the compounds in question. Said thermal spray powder is used to deposit, via the plasma spraying technique, a silicon carbide-based coating on a metallic or non-metallic substrate. The figure shows the X-ray crystallogram obtained, for a silicon carbide-based powder, according to the invention, after thermal spraying. The substantial identity of this crystallogram with the one obtained prior to thermal spraying demonstrates that the silicon carbide has been deposited on the substrate without decomposing.

    摘要： A process for the preparation of a composite multilayer product with selective optical properties comprises the operation of depositing, by thermal plasma spraying of powders, a coating of semiconductor oxides doped with oxides of elements chosen from the group consisting of transition metals and metals in the groups III-A and V-A of the periodic table of elements, in which the coating obtained maintains the composition and doping of the thermal plasma sprayed powders substantially unchanged. The figure shows the X-ray diffraction spectrum of a coating deposited according to the process of the present invention.

    摘要： Process for the preparation of articles in Titanium coated with a layer of Titanium oxide is described, wherein the metallic Titanium is subjected to the following steps: optional conditioning of the surface; anodic oxidation treatment, in an electrolytic cell of which it represents the anode, in a bath made of an aqueous solution comprising sulfuric acid, hydrochloric acid and hydrofluoric acid; and forming onto the metallic surface, by effect of electrolysis, an oxide layer having a >1 nullm thickness and containing a single crystalline phase made of anatase (one of the two allotropic tetragonal shapes of Titanium oxide). Object of the invention are also the articles in Titanium coated with a thick layer of anatase so obtainable, and the use thereof as photocatalysts, under the action of an ultraviolet radiation.
