Method for imparting conductivity to insulating ceramics and method for processing |
| abstract |
(57) [Abstract] [Purpose] The present invention relates to a method of imparting conductivity and a machining method such as engraving and piercing for electric discharge machining of insulating ceramics. [Structure] A ceramic in which a part of constituent elements is decomposed and sublimated by irradiating a high-density energy such as a laser is irradiated with a laser in a non-oxidizing atmosphere to impart conductivity. Moreover, after a conductive alteration layer is formed by applying a heat quantity of 3 kJ / cm 2 or more to the surface layer of silicon nitride using a laser in a non-oxidizing atmosphere, the conductive alteration layer is extended while performing various processes. , Process into a predetermined shape. |
