“…The modifications can be classified into three categories: surface oxidation of the metal construction materials, 2 metallic coating with low hydrogen permeability, such as molybdenum, 3 tungsten, 4 etc., [5][6][7][8][9][10] and nonmetallic coating, such as Al 2 O 3 , 11 TiN, 12 TiC, 13 and their composite films. [14][15][16] Sugizaki et al 12 found that nitrogen implantation into titanium significantly affected hydrogen absorption, which might be caused by the formation of TiN precipitation in the implanted layer.…”

The hydrogen impermeability of titanium nitride films and its dependence on nitrogen concentration have been estimated by molten salt electrochemical techniques at 723 K. Surface nitriding of titanium substrates was conducted by two methods, i.e., gas nitriding and molten salt electrochemical nitriding. Hydrogen concentration in the titanium nitride films was directly measured by elastic recoil detection (ERD) analysis. It was confirmed that the titanium nitride film worked as a hydrogen permeation barrier at high temperatures. When titanium coexisted with titanium nitrides, the hydrogen impermeability decreased with the increase of the volume concentration of titanium, which worked as the hydrogen-diffusing medium.

“…Due to the combined properties of high melting point, high hardness, good thermal shock resistance and chemical/physical sputtering resistance under bombardment by highly energetic particles [7,8], much research of high heat flux components has been carried out on TiC coatings [9][10][11][12]. During heat loading and unloading, however, the protective layer suffers thermal stresses that originated from mismatch of CTEs between two different materials [13].…”
