PROTECTION OF TITANIUM AGAINST HYDROGEN EMBRITTLEMENT
2019
The protective coatings of Al2O3 and AlN on iodide titanium in initial state and after annealing in a hydrogen atmosphere were investigated by scanning electron microscopy. It was found that the coatings protect titanium from the interaction with hydrogen at a pressure of 0.6 MPa up to 650 °C. It was shown that at 700 °C and pressure 0.6 MPa cracking of the protective coatings occurred, and the process of active absorption of hydrogen started.
