Abstract
This work describes a study of the growth of a Mo2B5 layer, obtained by diffusion of boron produced by cathodic reduction of KBF4 on molybdenum metal in molten fluorides, at 830°C.
The growth of the Mo2B5 layer has been studied by the galvanostatic method, and is controlled by diffusion of boron in the boride layer.
The experimental results show that boriding may occur with about 100% Faraday efficiency, and the calculated diffusion coefficient of boron in the surface layer is in agreement with the literature data obtained by chemical vapour boriding studies.
