The Mechanism of Titanium Passivation in Sulfuric and Hydrochloric Acid Solutions,

One of the fundamental problems involved in the study of the passivation of metals is an explanation of the nature and means of the phenomenons initiation. In an attempt to explain the mechanism of titanium VT1-1 brand passivation, the article studies its electro-chemical behavior in 5 and 10 N solutions of sulfuric and hydrochloric acid using the following methods relaxation of polarization, stationary and nonstationary curves, potential drop curves, and the alternating current method. This article also measures the amount of electricity expended in a given period of time on anode passivation of titanium and on the reduction of oxide films which form at various passivation potentials.
