Study of expanded austenite formed in plasma nitrided AISI 316L samples, using synchrotron radiation diffraction [PDF]
Materials Research, 2014 AISI 316L stainless steel samples nitrided at different conditions of temperature and time, showing different properties, such as nitrogen concentration (C N) and nitrided layer thickness, were studied. Expanded austenite (γN) diffraction peaks up to the

On the Nitrogen Diffusion in a Duplex Stainless Steel [PDF]
Materials Research, 2015 Duplex Stainless Steels (DSS) have excellent corrosion resistance properties and poor wear resistance. Plasma nitriding is used to increase the surface hardness, by nitrogen diffusion into the crystal lattice, and to improve wear resistance.

Improved Tribocorrosion Resistance of a CoCrMo Implant Material by Carburising
Lubricants, 2018 Tribocorrosion damage is a cause for the premature failure of hip implants made of cobalt-based alloys. Low-temperature carburising can be a plausible solution towards mitigating the tribocorrosion damage of articulating components.

Kinetics of Stainless Steel Material by Plasma nitriding Process for sustainable applications [PDF]
E3S Web of ConferencesImplantation of ion at low temperature and nitriding through plasma process at low-temperature prevents the corrosion resistance in stainless steel material. The outcome of nitriding process is to form precipitation of CrN on the surface. For the current

Effect of C2H2/H2 Gas Mixture Ratio in Direct Low-Temperature Vacuum Carburization
Metals, 2018 The effect of the acetylene and hydrogen gases mixture ratios in direct low-temperature vacuum carburization was investigated. The gas ratio is an important parameter for producing free radicals in carburization.

Karl Popper and the Mechanisms of Hydrogen Embrittlement
Advanced Engineering Materials, EarlyView.Representation of the beginning of loss of ductility rather than embrittlement. Small concentrations of hydrogen in a diffusible form within iron are well‐established to harm the mechanical integrity of steels. There are theories that attempt to explain the pernicious role of hydrogen.
