Publication number: 20060222862Abstract: A material composed of brittle material fine particles, such as ceramic or metalloid fine particles, for forming a composite structure on a substrate surface. The brittle material is pretreated to achieve a specific size range of fine particles and to develop a desired range of internal strain therein. The brittle material fine particles are adapted to form an aerosol with a gas stream, and when the aerosol is ejected to collide with a substrate surface, this causes collision of brittle material fine particles with a substrate surface thus imparting a mechanical impact to the fine particles. Such mechanical impact fractures or deforms the particles, and thereby generates an active new surface for brittle material fine particles after being fractured or deformed.Type: ApplicationFiled: May 22, 2006Publication date: October 5, 2006Applicants: TOTO LTD., National Institute of Advanced Industrial Science and TechnologyInventors: Jun Akedo, Tomokadsu Ito, Tatsuro Yokoyama, Katsuhiko Mori, Hironori Hatono, Masakatsu Kiyohara, Yuji Aso
