METAL PART NITRIDING METHOD FOR IMPROVING THE SURFACE HARDNESS OF A METAL PART THROUGH QUENCHING AND TEMPER-NITRIDATION

摘要

PURPOSE: A metal part nitriding method is provided to implement tempering and plating at a time by temper-nitriding a metal part, thereby reducing production processes.;CONSTITUTION: A metal part nitriding method comprises the steps of: quenching a metal part, temper-nitriding the metal part, and maintaining the metal part at a temperature of 600-700 degrees in a mixed gas atmosphere of oxidative gas and nitrogen for 30 minutes or longer so that a nitride compound layer(200) is formed in the surface of the metal part.;COPYRIGHT KIPO 2012
