    摘要： A method for producing a surface-modified component includes: a process of forming a thermal sprayed coating on a substrate; a process of irradiating a surface of the thermal sprayed coating with a high energy beam so as to cause an entirety of the thermal sprayed coating and a part of the substrate in a thickness direction to melt and then solidify, and thereby forming a densified modified layer; a process of forming a thermal sprayed coating on the modified layer which has been formed in the latest; and a process of irradiating a surface of the thermal sprayed coating with a high energy beam so as to cause an entirety of the thermal sprayed coating and a part of the modified layer which has been formed in the latest in the thickness direction to melt and then solidify, and thereby forming a densified modified layer.

    摘要： A ceramic substrate (2) is irradiated in an atmospheric air with a laser having a power density of 1.0 × 10 7 - 1.0 × 10 9 W/cm 2 for an action time on an irradiation area of 1.0 × 10 -7 - 1.0 × 10 -5 s to roughen a surface of the ceramic substrate (2), as well as to form an oxide layer (3) on a roughened surface (2a). This yields high adhesion to a thermal sprayed coating formed on the ceramic substrate (2), due to the action of chemical affinity in addition to physical adhesion force of the roughened surface (2a), without causing any great reduction in substrate strength.
