Ion-nitriding for 17-4PH Stainless Steel

Hua Zhou

Abstract

The process and microstructure of ion nitrided 17 4PH stainless steel was studied by orthogonal design experiment.The results show that the main factors are the nitriding temperature and time.The hardness increases from 514HV0 1 to 1290HV0 1 with temperature increasing from 480℃ to 560℃.At 520 ℃,the surface hardness increases from 814HV0 1 to 1290HV0 1 when nitriding time is prolonged from 3h to 7h.
