Title:
METHOD FOR ROUGHENING SUBSTRATE, METHOD FOR SURFACE-TREATING SUBSTRATE, METHOD FOR PRODUCING SPRAY-COATED MEMBER, AND SPRAY-COATED MEMBER
Document Type and Number:
WIPO Patent Application WO/2016/170895
Kind Code:
A1
Abstract:
A ceramic substrate (2) is irradiated in atmospheric air by a laser having a power density of 1.0 × 107-109 W/cm2, in which the duration of action on an irradiation position is set to 1.0 × 10-7-10-5, the surface of the ceramic substrate (2) is roughened, and an oxide film 3 is formed on the roughened surface (2a). This yields high adhesiveness to a spray coating, formed on the ceramic substrate (2), due to the action of chemical affinity in addition to the physical adhesive force of the roughened surface (2a), without causing any great reduction in substrate strength.
