Machinohydrogen treatment of titanium alloys by turning to remove of oxide layers
Hydrogen effects on titanium alloys turning in the removing of thick oxide layers from deformed semi products and castings were investigated. It was shown that the two directions of turning improvement may be possible: <i>a) </i>the preliminary hydrogenation under certain conditions leads to the decreasing of oxide layers thickness and its softening; <i>b) </i>hydrogen interaction with preexistent oxide layers during hydrogenated annealing leads to the softening of oxide layers and it cohesion worsening with the metal.
