A Brief Review on TiO₂ Coating Deposited by Cold Spraying

Abstract:

TiO₂ is a promising photocatalyst with great potential for environment purification and energy conversion. TiO₂ coatings have more advantages over powders in practical use. Cold spraying is an ideal technique to fabricate TiO₂ coatings because of its low heat input compared with thermal sparing which may induce undesirable phase transformation from anatase to rutile. The paper will give a short introduction on recent development of TiO₂ coatings by cold spraying. Then, the factors affecting the quality of coating should be analyzed. And finally, the bonding mechanism of cold sprayed TiO₂ coating on metal substrates will also be proposed.
