Notes:
Nitridation of polycrystalline titanium was investigated in situ at about 550°C by angle-resolved x-ray photoelectron spectroscopy (XPS). The nitrogen pressure was varied from 10-4mbar to 1 mbar. The distribution of nitrogen in the titanium and the chemical bonding present were deduced from XPS measurements. Titanium nitridation passes through several stages as a function of the nitrogen exposure. The nitrogen concentration varies linearly with the logarithm of pressure and dose. Using the modified Ritchie-Hund theory it was shown that the kinetics of titanium nitridation follows a cubic law.
