Description

Corrosion resistance of nitrified titanium was evaluated by measurement of corrosion potential and corrosion rate in 20% HCl and H2SO4. It was found that nitride layer remarkably inhibits active dissolution of titanium in these acid solutions. There is a correlation between the structure of nitride layer and potential decay curve. X-ray analysis showed the existence of only TiN and ε-TiN in the nitride layer, but the results of potential measurement and chemical analysis of dissolved ions suggested the existence of unknown higher nitride which composes the outermost thin layer.
