Method for cold gas spraying

摘要

Method for cold gas spraying involves accelerating wettable-powder containing photocatalytically active spray particles in nozzle using carrier gas, and coating to substrate. At least a portion of the photocatalytically active spray particles contain nano-crystalline agglomerates having porosity of 200-800 m 2>/g, determined by Brunauer-Emmett-Teller nitrogen measurement. Independent claims are included for the following: (1) coating material; and (2) article.
