Abstract
A method for joining a ceramic material to a metallic material includes: forming a metallic film on the surface of the joining area of the ceramic material; irradiating the metallic film with high energy ions to allow the metallic film to stick firm to the surface of the ceramic material and to strengthen the surface of the ceramic material; and mechanically joining the ceramic material to the counterpart metallic material through the metallic film. The ceramic material subjected to these steps hardly breaks at the joining area where breaking otherwise occurs easily, thus enabling high-strength joining of ceramic and metallic materials.
