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 ...

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.

Low-Temperature Carburization: Ex Situ Activation of Austenitic Stainless Steel
Metals, 2023 Surface engineering of chromium-oxide-passivated alloys (e.g., stainless steels) by low-temperature infusion of interstitial solutes (carbon, nitrogen) from a gas phase requires “surface activation” by removing or perforating the passivating oxide film ...
