Advantages of Passivation of Titanium

Titanium provides high specific strength, good high temperature properties and exceptional corrosion resistance. Titanium's corrosion resistance is provided by a tightly adherent TiO2 film. Its excellent corrosion resistance makes titanium an option for chemical processing equipment, marine equipment, biomedical implants and much more.

While titanium possesses excellent corrosion resistance, it still may be affected by surface contaminates and oxides which may be removed by passivation and finishing. Titanium can be mechanically polished to improve surface finishreduce product adhesion and to improve cleanability. Harrison Electropolishing can mechanically polish titanium and certify surface finishes as low as 4 Ra micro-inches.

INDUSTRY STANDARDS

  • ASTM B600

 

The passivation of titanium does not affect or improve its corrosion resistant oxide layer. However, passivation of titanium does remove iron and other surfaces contaminates. Harrison Electropolishing can passivate titanium assemblies of all sizes to ASTM specifications, or your industry or company specific requirements.

Harrison Electropolishing can oxygen clean and chemical clean a wide range of titanium components.
