    • An electric discharge type device is described having electrode means which include a refractory metal substrate having sintered thereon an open porous coating of refractory metal particles at a thickness up to about 1 millimeter thickness with electron emissive material being disposed in the pores of said sintered refractory metal coating. Representative electric discharge devices having said improved electrode means include discharge type electric lamps and photographic flash tubes wherein the electrode members have an elongated shaped body which is terminated at one end to provide more surface area for the coatings sintered thereon. Various electron emissive materials can be employed for impregnation of the open porous coating of refractory metal particles by such conventional techniques as dipping or spraying.
    • 描述了具有电极装置的电极装置,该电极装置包括在其上烧结厚度达约1毫米厚度的难熔金属颗粒的开放多孔涂层的难熔金属基底,电子发射材料设置在所述烧结难熔金属的孔中 涂层。 具有所述改进的电极装置的代表性放电装置包括放电型电灯和照相闪光管,其中电极构件具有细长成形体,其在一端处端接,以为其上烧结的涂层提供更多的表面积。 各种电子发射材料可用于通过浸渍或喷涂的常规技术浸渍难熔金属颗粒的开孔多孔涂层。
