摘要：

Titanium dissolved in concentrated hydrochloric acid under valences III and IV. The stationary current-voltage curve is consistent, in a wide potential range, with a reaction model similar to that proposed for the fluorinated sulphuric media. Nevertheless there exist discrepancies between the behaviours in the two types of media. In particular an oxide formation and a particular variation with the potential of the product Rt×I (transfer resistance × stationary current) are specific to the hydrochloric media. © 1979.
