    1,Product description

    Titanium is a corrosion-resistant metal that reacts with oxygen to form a stable and dense oxide film that is stable in oxidizing, neutral or weakly reducing media. Therefore, industrial pure titanium can be used directly in many media, or a suitable corrosion inhibitor can be added to the medium [1]. However, titanium generally does not have corrosion resistance in a reducing acid solution. The addition of Pd to titanium can improve the resistance of titanium to reducing acid corrosion, and at the same time improve the crevice corrosion resistance of titanium.

    Ti-Pd alloys include Ti-0.2Pd, Ti-0.15Pd and Ti-0.13Pd, among which Ti-0.2Pd is widely used in reactors, towers, autoclaves and heat exchangers for various corrosive environments. , pumps, valves, centrifuges, separators, pipes, fittings, electrolyzers.
