Titanium Palladium Alloy Material National Standard TA 9 American Standard GR7 Titanium Alloy Corrosion Resistance Analysis

Original Title: Analysis of Corrosion Resistance of Titanium Palladium Alloy Material in National Standard TA 9 and American Standard GR7 Titanium has strong corrosion resistance in many media, especially in neutral and oxidizing media, and can also be used in some dilute reducing acids, such as nitric acid of various concentrations from room temperature to boiling point. It has good corrosion resistance to most alkali solutions, such as barium hydroxide, calcium hydroxide and magnesium hydroxide saturated solutions at room temperature, but it can not be used in boiling sodium hydroxide solution. Titanium does not corrode at all in sea water and is resistant to most organic acids (except formic acid and oxalic acid). Excellent corrosion resistance in wet chlorine and chloride solutions such as chlorite and hypochlorite. The corrosion resistance in sodium chloride solution increases with the increase of pH value of the solution. Titanium and its alloys are widely used in chemical equipment,3d titanium wire, petroleum industry and food industry, and have been extended to aerospace and biomedical fields due to their light weight, high strength,titanium plate gr7, good biocompatibility and corrosion resistance. Although the electrode potential of titanium is relatively low and its nature is very active, in many media, titanium can exist stably and not be corroded, mainly because in the air or other media, the surface of titanium quickly forms a layer of dense and strong adhesion oxide film with a certain self-repair ability. Compared with titanium, titanium-palladium alloy has stronger corrosion in many reducing media and stronger crevice corrosion resistance than titanium. Palladium in titanium-palladium alloy is a good alloying element for titanium because it shows a certain cathodic effect and can change the anodic polarization characteristics of titanium. Oxalic acid is a kind of organic reducing acid, titanium plate gr7 ,Titanium welding pipe, which can complex many kinds of metal ions like citric acid. Titanium has good corrosion resistance in many media, but it will produce hydrogen depolarization corrosion in oxalic acid.
