Technical Field

[0002] Carbonitriding is a process that uses chemical reactions to simultaneously penetrate nitrogen and carbon into the surface of steel parts at high temperatures, forming a carbonitriding layer of a certain thickness. The nitrogen element in this layer can increase the hardness of the steel parts, while the carbon element can increase the strength and toughness of the steel parts. High-frequency quenching uses the induced heat generated instantly by high-frequency current to rapidly heat the surface of the steel parts to above the critical temperature, and then through rapid cooling, a martensitic structure with high hardness and high strength is formed on the surface.
