Abstract
Fast union of a ceramic article to an opposed material is attained by a method which comprises forming a film of metal on the surface of the ceramic article, irradiating the surface of the metallic film with high-energy ions to bind the metallic film fast to the ceramic article, and supplying solder or brazing alloy to the surface of the metallic film and soldering or brazing the ceramic article to the opposed article. The high-energy ions for the irradiation has a magnitude of 30 to 800 keV and the dosage of the high-energy ions is in the range of 5.times.10.sup.15 to 2.times.10.sup.18 ions/cm.sup.2.
