Paper Title:
Study of Reactive Plasma Sprayed TiN Electrocatalytic Carrier Coatings
  Abstract

In this paper TiN coating as an interlayer was fabricated on Q235 steel substrate by reactive plasma spray method and its microstructure and influences on the performance of the Fe/TiN/PO2 electrode were investigated. It is shown that the TiN coating has a rough surface and layered cross-section structure. The coating consists of main TiN phase and a small quantity of Ti oxides. After heat-treated below 550°C the TiN coating is greatly densified due to the increase of Ti oxides, and however the electric resistance of the Fe/TiN samples is still lower than that of the Ti substrate. For the Fe/TiN/PbO2 electrode a rougher surface and more micropores were observed in the active PbO2 coating than on the surface of the Ti/PbO2 electrode. Due to the presence of the TiN interlayer the Fe/TiN/PbO2 electrode shows an accelerated life of 180h under the test condition, which is much longer than 28min of the Ti/PbO2 electrode.
