Researchers at the UPV/EHU-University of the Basque Country, Spain, say they have validated a laser scanning optics system that may enable laser hardening of steel parts of varying shape and thickness at an industrial scale.
The success of plasma and gas nitriding at low temperatures (lower than 840°F) and solution nitriding at high temperatures is associated with the absence of chromium nitride or carbide precipitation, and thus with the formation in the surface layer of a particular phase called the S-phase.
Battery researchers seeking improved electrode materials have focused on “tunneled” structures that make it easier for charge-carrying ions to move in and out of the electrode.
