| Summary: | Заглавие с экрана In this paper, the increase in hydrogen resistance, mechanical and tribological properties of E110 alloy samples by TiN protective coating deposition under high-temperature gas-phase hydrogenation at 350° C, 450° C and 900° C was shown. The crystalline structure, surface morphology and depth distribution of elements were analyzed by X-ray diffraction, optical microscopy and glow-discharge optical emission spectroscopy, respectively. The intensity of hydrogen absorption by TiN-coated E110 alloy increases with hydrogenation temperature. Hardness and Young's modulus of the TiN coatings slightly changed under hydrogenation up to 450°C and dropped at 900°C. No cracks or delaminations were observed on the surface of TiN-coated samples after hydrogenation up to 450°C, however, the film was cracked after hydrogenation at 900° C. Evolution of friction coefficient of hydrogenated samples was shown. |
