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 ...

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 ...

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.

Parameter Design in Carbonitriding of EN36, 16MnCr5, and AISI 4140 Steels Using Principal Component‐Based Grey Incidence (PGI)

Advances in Materials Science and Engineering, Volume 2022, Issue 1, 2022., 2022
Case‐hardening steels (EN36, 16MnCr5, and AISI 4140) are used in applications demanding good surface properties such as precision gears, shafts, and cam rollers. This study explores the formation of microcoatings to improve the surface characteristics of these steels using carbonitriding, which combines the merits of carburizing and nitriding to offer ...
