Duplex Stainless Steel Laser‐Surface Textured: Stability in Brine Solution

Advanced Engineering Materials, Volume 28, Issue 8, 22 April 2026.
Controlled laser‐surface treatment (LST) of duplex DSS2205 steel is performed to increase its stability in brine solution under cyclic electrochemical assays. The superior protection with respect to flat and smooth panels is attributed to the presence of FeCr2O4 as the main protective oxide layer in the LST surface, after corrosion tests. The stability

Low‐Temperature Thermochemical Treatments of Face‐Centered Cubic Alloys: New Perspectives for Expanded Austenite From Austenitic Stainless Steels to High‐Entropy Alloys

MetalMat, Volume 2, Issue 3, September 2025.
Expanded austenite is a supersaturated solid solution of nitrogen and/or carbon in a metal face‐centered cubic lattice, produced by surface treatments at low temperatures. The review discusses the characteristics and properties of this phase formed on austenitic stainless steels, nickel and cobalt alloys and entropy alloys, highlighting the ...

New Approach for Plasma Nitrocarburizing of Stainless Steels by a Modified Reactor Configuration Using a Plasma‐Activated Solid Carbon Precursor

steel research international, Volume 96, Issue 5, May 2025.
The defined adjustment of the properties of plasma nitrocarburized steels requires a precise control over the generated treatment‐relevant gas species with respect to their type and concentrations. Therefore, a modified hot‐wall reactor is developed by implementing a separate plasma‐activated solid carbon precursor while concentrations of the resulting

Effect of Treatment Temperature on the Cyclic Spherical Contact Behavior of Plasma Nitrided and Nitrocarburized AISI 321 Steel [PDF]

Materials Research
This work studied the cyclic spherical contact behavior of plasma nitrided (N) and nitrocarburized (NC) AISI 321 steel. The temperature and exposition time were 400 and 500 °C for 6 h in each treatment. A superficial hardness between ~10 (NC 400 °C) and ~
