Low‐Pressure Nitrocarburizing in Standard Vacuum Furnaces—Preliminary Studies

Advanced Engineering Materials, Volume 25, Issue 24, December 2023., 2023
Low‐pressure nitrocarburizing is performed in a standard vacuum furnace, using ammonia/acetylene atmosphere. Performed studies confirm the safety of the process—no toxic gases and undesired deposit are generated during the process. Nitrocarburizing of 16MnCr5 alloy steel samples results in the increase in hardness and formation of 20 μm effective case ...

Nitriding of White‐Solidified Fe–C–Si Alloys: Diffusion Path Concept Applied to Inhomogeneous Microstructures

Advanced Engineering Materials, Volume 24, Issue 3, March 2022., 2022
The Fe nitride and compound layer formation during nitriding of white‐solidified Fe–C–Si alloys is studied. Due to the heterogeneous distribution and limited diffusivity of Si, different microstructure regions behave like different alloys being nitrided simultaneously.

Effect of the PEN/C surface layer modification on the microstructure, mechanical and tribological properties of the 30CrMnSiA mild-carbon steel

Journal of Materials Research and Technology, 2020
As result of plasma-electrolytic nitrocarburizing 30CrMnSiA carbon steel (ferrite-perlite grade), there was a change in the elemental and phase composition, as well as the surface layer microstructure (40 ÷ 45 microns thick from the surface). A formation
