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

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 ...

Effect of applied chemical heat treatment on the structure and properties of low-alloy Cr-containing iron powders [PDF]
The article presents experimental results on the application of thermal oxidation or low temperature gas nitrocarburizing (LTGNC) of Ecosint powders sintered under industrial conditions. Surface hardness HRB and microhardness (HV0.1) were studied.

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

Thermochemical Corrosion of Furnace Materials in Atmospheres Containing Ammonia
The present research focuses on determining the long‐term effects of ammonia‐containing atmospheres on the metallic furnace materials AISI 309, AISI 314, Alloy 600, and Alloy 601. The materials studied were exposed to numerous nitriding or nitrocarburizing treatments for more than 10 years to investigate the long‐term effects of repeated contact with ...
