Comparison of Boriding Heat Treatment and Induction Boriding Method
International Scientific and Vocational Studies Journal, 2023 Induction boriding is a metal processing technique that applies a surface accumulation process using a high-frequency electromagnetic field on metal parts. The adoption of this method in industrial applications is anticipated due to its advantages such as high efficiency, precision, and low energy consumption. Induction boriding relies on the principle

Hydrogenation of Magnesium Nickel Boride for Reversible Hydrogen Storage [PDF]
, 2010 We report that a ternary magnesium nickel boride (MgNi_(2.5)B_2) mixed with LiH and MgH_2 can be hydrogenated reversibly forming LiBH_4 and Mg_2NiH_4 at temperatures below 300 °C. The ternary boride was prepared by sintering a mechanically milled mixture
