The data show that the corrosion resistance of Ti-0.2 Pd in reducing medium is significantly better than that of industrial pure Titanium, and the welding zone of Ti-0.2Pd is the same as the corrosion resistance of the base material. Ti - 0.2 - Pd in charge of hydrochloric acid and the air in the air compared with steady potential significant positive move, corrosion speed could drop by 10 times, but in the acid solution of argon or nitrogen filling, constantly changing new corrosion solution or sample solution volume increase per unit area, the passivation performance of Ti - 0.2 - Pd declined obviously, therefore should be avoided under the condition of anaerobic or oxidant completely using Ti - 0.2 Pd. Adding a small amount of palladium GR7 Titanium alloy corrosion resistance in oxidizing medium is improved, especially the crevice corrosion resistance. Therefore it is widely used in hydrochloric acid, sulfuric acid, phosphoric acid, nitric acid, chloride corrosion medi
