Abstract:

:By analyzing the voltage and breakdown voltage of titanium surface in the micro-arc oxidation process varying with the time, the solution concentration and the applied current density, the surface electrical breakdown behaviors of titanium in different electrolyte solutions are investigated. The results show that  in the micro-arc oxidation process, the electrode voltage uniformly and crenellatedly varies with the time and decreases with the increase in concentrations of two electrolyte solutions;  the breakdown voltage of the ceramic membrane surface exponentially decays with the increase of solution concentration; and  at a certain solution concentration, the breakdown voltage has no obvious relation to the applied current intensity.

Key words: micro-arc oxidation, titanium, breakdown voltage
