The cathodic and anodic potentiostatic polarization curves of titanium and its alloys in sulfuric and hydrochloric acid solutions were investigated. It is shown that an increase in acid concentration causes an increase in the passivation current and a shift of the total passivation potential in the direction of positive values. An increase in temperature has the same effect. The cathodic hydrogen overvoltage is considerably lower (by 350-400 mv) for platinum and palladium alloys of titanium. As a result the steady state potential of the alloys undergoes a positive shift falling in the region of partial or complete passivation of titanium. The latter circumstance considerably increases the corrosion resistance of titanium alloys with platinum and palladium (1-2%). (tr-auth)
