Effect of Megaplastic Deformation in a Bridgman Chamber at Various Temperatures on the Corrosion Resistance of VT1-0 Titanium

The microhardness of VT1-0 titanium subjected to megaplastic deformation by torsion under a high hydrostatic pressure at room and cryogenic temperatures and its corrosion resistance in a 1 M solution of HCl are studied. It is shown that megaplastic deformation changes the passivation ability of titanium during anodic polarization: dissolution peaks appear in polarization curves and increase with the deformation.
