放电表面处理方法及修理方法
Abstract:
一种放电表面处理方法及修理方法，其中，在电极(37)的末端面与金属板(11)的端面之间产生脉冲状放电，使电极(37)消耗，在电极(37)的前端面形成与金属板(11)的端面形状一致的凹处(41)，在使电极(37)向与金属板(11)的侧面正交的方向相对地移动的同时，在电极(37)的凹处(41)的内侧面与金属板(11)的端面的侧面(11bl(11cl)、11br(11cr))之间产生脉冲状放电，在金属板(11)的端面的侧面(11bl(11cl)、11br(11cr))形成辅助保护膜(43、45)，在电极(37)的凹处(41)的里面与金属板(11)的端面的前端面(11bu(11cu))之间产生脉冲状放电，在金属板(11)的端面形成加厚层(47)。
Abstract(English):

An electrode (37) is consumed by generating pulsating discharge between the distal end face of the electrode (37) and the end face of a metal plate (11) to form a recess (41) copying the profile of the end face of the metal plate (11) in the distal end face of the electrode (37). While moving the electrode (37) relatively in the direction intersecting the side face of the metal plate (11) perpendicularly, pulsating discharge is generated between the inner side face of the recess (41) in the electrode (37) and the side faces (11bl(11cl)), (11br(11cr)) of the end face of the metal plate (11) toform auxiliary coatings (43, 45) on the side faces (11bl(11cl)), (11br(11cr)) of the end face of the metal plate (11). Pulsating discharge is generated between the rear face of the recess (41) in theelectrode (37) and the distal end faces (11bu(11cu)) of the end face of the metal plate (11) to form a cladding layer (47) on the end face of the metal plate (11).
