Title: STUDIES ON THE MECHANISM OF ELECTROCHEMICAL CORROSION OF TITANIUM. I. THE EFFECT OF HALIDE IONS ON THE CORROSION AND ELECTROCHEMICAL BEHAVIOR OF TITANIUM IN SULFURIC ACID (in Russian)

Abstract

The corrosion behavior of titanium is determined by the presence of a protective oxide film on its surface. The halide ions Cl/sup -/ and Br/sup -/ in sulfuric acid in an atmosphere of air and of hydrogen have a double effect on the corrosion of titanium activating it in dilute acid solutions and retarding the corrosion in more concentrated solutions. In all sulfuric acid solutions studied I/sup -/ ions passivate titanium in air, whereas in hydrogen this is true only for concentrated solutions. The retardation of titanium corrosion by halide ions may be explained by their forming adsorbed or phase protective films on the titanium surface. The dissolution of titanium in sulfuric acid obeys the laws of electrochemical kinetics. (auth)
