Titanium is a silvery-white metal which is widely distributed in the Earth's crust. The titanium mechanical properties depend essentially on the metal purity. Titanium alloys have a high specific strength even at high temperatures, and maintain high ductility and high corrosion resistance, as compared with commercial titanium. Titanium is widely used in shipbuilding and transport engineering, rocket and space engineering and etc. Low density combined with high specific strength and corrosion resistance favour the use of titanium. Application of titanium in aircraft construction allowed to break the sound barrier. Titanium alloy are used in manufacture of rocket panels and frames, fuselage and wing skin for high-speed aircrafts, turbine blades and plates. Thanks to high chloride resistance titanium containers can be used for the radioactive waste disposal in special underground pits and galleries. Since titanium has full biological compatibility with human tissue, it is widely used in medicine. Bone and muscle tissues do not reject titanium. The metal is also used for the manufacture of cardiovascular valves, electronic stimulators and as denture implants.
Compounds of titanium with nitrogen content from 14.8 to 22.6 % (titanium nitride) have rather wide application. Due to its heat resistance titanium is used in manufacture of crucibles for oxygen-free melting of metals. It is also used to obtain decorative and abrasion resistant coatings. Titanium nitride with various concentrations of nitrogen takes various shades of gold and can replace gold where its use is not rational because of its high cost.
Performance of titanium electrolyte-plasma treatment and polishing:
Recommended processing time for titanium polishing — 180 sec.
Grinding and deburring speed — 30 sec.
Average time to reduce the roughness value by 1 class — 60 sec.
The number of polishing cycles before changing the electrolyte — 120.
