Optimization of gaseous nitriding process parameters for hard surface layer of duplex stainless steel

The optimization for gaseous nitriding process parameters of duplex stainless steel was performed using Taguchi approach. The nitriding process parameters of temperature, time and gas mixture ratio of NH3 and N2 are considered as input parameters. Three responses are chosen which are surface hardnes...
