摘要： An electrolytic test machine is used for a corrosion resistance test for a test material comprised of a metal blank and a coating film. The electrolytic test machine is constructed so that an adverse influence, due to chlorine gas generated during a test, can be inhibited. The electrolytic test machine includes an electrolytic cell in which an aqueous solution of NaCl is stored so that a test material is immersed in the aqueous solution of NaCl. An electrode is immersed in the aqueous solution of NaCl. A DC power source supplies electric current between the electrode and the test material. A chlorine gas treating device collects chlorine gas which is generated with electrolysis of the aqueous solution of NaCl and which is released out of the aqueous solution of NaCl along with the aqueous solution of NaCl. The chlorine gas treating device includes a treating pipe line, a suction pump mounted on the treating pipe line, and a chlorine gas purifying member.

摘要： A manufacturing method of an impregnation type cathode for removing emitter material remaining on the porous sintered body pellets, includes steps for impregnating the emitter material into void spaces between the porous sintered body pellets, heating a phosphoric compound in a vessel up to the temperature in a range of about 100.degree. C. to about 300.degree. C., and dipping the impregnated emitter material into the heated phosphoric compound. The manufacturing method of the present invention creates a cathode which operates stably for a long time with high current density because there is no damage caused when the remaining emitter material is removed from the surface of the porous sintered body pellets.
