METAL SURFACE HARDENING TECHNIQUE USING ELECTRON-BEAM INJECTION TO IMPROVE THE HARDNESS AND ABRASION RESISTANCE OF METAL

摘要

PURPOSE: Metal surface hardening technique using electron-beam injection is provided to improve the properties of metal while preventing environmental contamination caused by the existing salt bath nitriding and ammonia gas nitriding.;CONSTITUTION: Metal surface hardening technique using electron-beam investigation is characterized in that the surface of a work piece(12) is hardened using electron-beam and reactive gas. The work piece is made of a metal, polymer, or ceramic material. The reactive gas is composed of carbon, nitrogen, or fluorine.;COPYRIGHT KIPO 2012
