    Abstract: Various examples are provided related to electrodes for high temperature electrochemical corrosion sensing. In one example, a high temperature sensor electrode includes a quartz tube; a copper chloride and sodium chloride mixture sealed in the quartz tube; and an electrode wire in the mixture, the electrode wire including an electrode connection extending through a seal of the quartz tube. In another example, a method for electrochemical testing includes immersing electrodes of a high temperature electrochemical sensor in a corrosive medium, the electrodes comprising a high temperature sensor electrode; and obtaining one or more electrochemical measurement via the electrodes immersed in the corrosive medium. The electrodes can also include a working electrode and/or a counter electrode.

    Abstract: An improved cathode comprises a cone-shaped emitter with a carbon-based coating applied to the emitter cone surface, in which there is a narrow annular gap between the emitter body and the carbon coating. The gap prevents direct contact between the carbon coating and the crystalline emitting material, thereby preventing damaging interactions and extending the useful lifetime of the cathode.

    Abstract translation: 改进的阴极包括锥形发射器,其具有施加到发射体锥表面的碳基涂层,其中在发射体和碳涂层之间存在窄的环形间隙。 间隙防止碳涂层和结晶发射材料之间的直接接触,从而防止损坏相互作用并延长阴极的使用寿命。
