Pulse plasma offers significantly more precision in nitriding through the control of the mixture of gases, the controllability of glow-discharge intervals, the design of the pulsed signal and the use of a highly insulated hot-wall nitride furnace. Together with innovations in the design of the furnaces to streamline batch management in nitriding operations, forgers can benefit from dies with superior surface hardness, wear resistance, heat resistance and fatigue strength.
