Corrosion potential measurements and analysis of polarization characteristics allowed to conclude that titanium VT1-0 with nano- and submicro grain structure shows higher electrochemical activity in 0,9% NaCl solution than its minor granular analogs. Formation of all types of anode oxide films in various modes, inclu- ding micro arc mode, on the titanium surface reduces and approximates corresponding indicators, but does not remove the differences, peculiar to substrates.
