Simultaneous surface engineering and bulk hardening of precipitation hardening stainless steel

Role of plasma nitriding temperature and time in the corrosion behaviour and microstructure evolution of 15-5 PH stainless steel

“…3c), cracks have occurred in the surface layer. According to Frandsen et al [14] and Yetim et al [24], nitridation leads to a high level of residual stresses in the surface layer, and these cracks result from the relaxation that occurs during metallographic preparation. According to Jeong and Kim [22], these stresses were produced during the formation of the CrN and Fe 4 N phases.…”

“…The effect of nitriding on the microstructure of precipitation-hardened steels has recently been the focus of studies by various authors [1,[12][13][14]. Gui-Jiang Li [2] has studied the wear resistance as well as microstructure evolution.…”

Carburizing treatment of low alloy steels: Effect of technological parameters

“…The depth of carburization is a function of carburising time and the carbon potential at the surface [1][2][3][4][5]. High carbon potential is suitable for short carburising times [6][7][8][9].…”

Plasma Nitriding and DLC Coatings for Corrosion Protection of Precipitation Hardening Stainless Steel

“…[1,2] Requirements for plastic molding dies are abrasion resistance, anti-sticking properties, and good corrosion resistance, among others. [1,2] The mechanical properties of these PH steels can be improved by means of plasma-assisted thermochemical treatments, such as plasma nitriding, -carburizing or -nitrocarburizing.…”

“…[1,2] Requirements for plastic molding dies are abrasion resistance, anti-sticking properties, and good corrosion resistance, among others. [1,2] The mechanical properties of these PH steels can be improved by means of plasma-assisted thermochemical treatments, such as plasma nitriding, -carburizing or -nitrocarburizing. [2,3] These treatments, when carried out at low temperature (T < 450 C), avoid the precipitation of nitrides/ carbides, allowing the growth of a diffusion layer rich in nitrogen or carbon.…”
