The absorption of oxygen and hydrogen by titanium during heat treatment with high frequency currents

This study presents experimental results of the investigation of the diffusion behavior of commercially pure titanium when interacting with oxygen and hydrogen. To study the gas absorption, electron microscopy combined with energy-dispersive analysis and secondary ion mass spectrometry were used. It was shown that in the course of heat treatment with high-frequency currents in the temperature range from 600 to 1200 °C, an intensive absorption of oxygen by the surface of titanium was observed. At the same time, desorption of hydrogen from the near-surface layer of titanium occurred and there was a double decrease in hydrogen concentration during thermal treatment in this temperature range.
