Publication number: 20130295272Abstract: The present invention relates to granules of a brittle material for room-temperature granule spray in vacuum, and to a method for forming a coating film using same. Particularly, particles having a size of 0.1 to 6 ?m are granulated and a coating film may be formed through room-temperature granule spray in vacuum using the granules. The granules of the brittle material according to exemplary embodiments may be used through the vacuum granule injection at room temperature and a coating process may be continuously performed. Since the granules injected through a nozzle have a relatively large mass and thus have a large amount of kinetic energy, the coating film may be formed at a low gas-flow rate, and the forming rate of the coating film may be increased. Therefore, the granules may be useful for forming a ceramic coating film.Type: ApplicationFiled: January 4, 2012Publication date: November 7, 2013Applicant: KOREA INSTITUTE OF MACHINERY AND MATERIALSInventors: Dong Soo Park, Jong-Woo Kim, Jung Ho Ryu, Woon-Ha Yoon, Jong Jin Choi, Byung-Dong Hahn
