Abstract
It is shown that the electrospark alloying of a titanium surface by palladium helps to enhance its corrosion stability in 10–40% solutions of H2SO4 at 100°C by 1–2 orders of magnitude. Mechanized alloying, as well as the additional heat treatment of electrospark palladium coated titanium (annealing in vacuum and electrothermal treatment in an electrolytic plasma), significantly raises its corrosion stability.
