Effects of Plasma-Chemical Composition on AISI 316L Surface Modification by Active Screen Nitrocarburizing Using Gaseous and Solid Carbon Precursors

Metals, 2021
Low-temperature plasma nitrocarburizing treatments are applied to improve the surface properties of austenitic stainless steels by forming an expanded austenite layer without impairing the excellent corrosion resistance of the steel.

Characterization of the expanded austenite developed on AISI 316 LM steel by plasma nitriding [PDF]

Journal of Mining and Metallurgy. Section B: Metallurgy, 2017
AISI 316 LM samples were plasma nitrided at a temperature of 380°C for different times between 0.5 and 8 h in a 85%N2- 15%H2 gas mixture. Different experimental techniques such as: optical microscopy (OM), X- ray diffraction (XRD ) and glow ...

Depth-Resolved Phase Analysis of Expanded Austenite Formed in Austenitic Stainless Steel [PDF]

Coatings, 2020
Expanded austenite γN formed after nitrogen insertion into austenitic stainless steel and CoCr alloys is known as a hard and very wear resistant phase. Nevertheless, no single composition and lattice expansion can describe this phase with nitrogen in solid solution.

Wear and Corrosion Study of Plasma Nitriding F53 Super duplex Stainless Steel [PDF]

Materials Research, 2016
Super duplex stainless steels (SDSS) have high corrosion resistance because of their high contents of chromium, nickel, molybdenum and nitrogen but low wear resistance.

The “Expanded” Phases in the Low-Temperature Treated Stainless Steels: A Review

Metals, 2022
Low-temperature treatments have become a valuable method for improving the surface hardness of stainless steels, and thus their tribological properties, without impairing their corrosion resistance.

Gradient self-organized dislocation in expanded austenite layer during low-temperature nitriding

Materials Research Express, 2023
A typical nitrogen expanded austenite layer is formed by plasma-based low-energy nitrogen ion implantation (PBLEII) on AISI 304L austenitic stainless steel at a moderate temperature of 380 °C.

High wear resistance and better pitting corrosion resistance of AISI 316L stainless steel by a self-protective oxy-nitrocarburizing paste

Journal of Materials Research and Technology, 2022
Simultaneous oxidation and nitrocarburizing of AISI 316 SS at 580 °C for 5, 10, 15, and 20 min were studied using self-protecting pastes of sodium cyanate and sodium carbonate.
