The electrochemical behavior of TiN films produced by three different
techniques was studied. Anodic polarization tests show that 110 keV N implantation into an iron sample coated with an 80 nm thick Ti layer
exhibits excellent corrosion resistance properties in 1N H2SO4 solutio
n. On the other hand, 110 keV N+ implantation into a sample coated wit
h a 500 nm thick Ti layer gives poor corrosion resistance properties.
These results are presented and discussed.
