Formation of Hydrides in the Surface Layer of Aluminum in NonEquilibrium Conditions of Electrolyte Plasma

“…Thus, with increasing current density, the number of lines that are identified with triple AlB 3 H 12 and NaAlH 4 is increased. According to layer by layer Xray and spectral analysis carried out on samples treated in electrolyte plasma in the regime with a current density ≥ 1.2 A/sm 2 (Table 1), the presence of these compounds and their depth of their occurrence depend on the boron and sodium distribution [7]. At low current density, boron diffuses to a lesser depth, and sodium practically does not diffuse into metal.…”

“…Analysis of the dependence of energy transferred to ions by electrons from the concentration of plasma and atomic mass of the ion, shows that the ions of hydrogen have the greatest energy [7,8].…”

“…It has been established [1][2][3][4][5][6] that the influence of hydrogen is multifactorial and is determined by the superposition of a number of factors depending on the conditions of treatment (type of energy source, the nature of the heating source, composition of the gas environment, duration of exposure), composition and structure of the metal. In the conditions of electrolyte plasma, which is formed as a result of discharges in an aqueous electrolyte solution [7], a hydrogen atmosphere is formed around the cathode, in which the diffusion of elements forming cathode space into the cathode proceeds.…”
