Application of Induction Heating to Boriding
Newly developed boriding process, which was performed by heating the metal using high-frequency induction furnace then melt the salt consisted of borax, carborundum and silicon carbide, was applied to several kinds of steels in order to find its feature. The study was carried out on the effect of chemical composition in steels and salts on the properties of the boride layer. Thick layer was obtained by using the salt containing carborundum. Increasing chromium content of the steels inhibited boriding and consequently needle-like boride layer changed into smooth one. Induction heating process offer thicker boride layer than the conventional immersion method.
