Oxidation activation of boriding with rapid high-frequency induction heating

1. The process of boriding from boron carbide powder with rapid high-frequency induction heating is provided primarily by B2O2 suboxide formed as the result of incomplete oxidation of boron by the oxygen of the air. 2. The composition of the gaseous medium will be determined by the heating rate and the gas permeability of the boron carbide powder, which depends upon the particle size and the thickness of the boron carbide layer. 3. Oxides of elements with lower affinities for oxygen than boron may be used as activators of the boriding process.
