Decomposition of expanded austenite in AISI 316L stainless steel nitrided at 723K
(2012-09-01)
Expanded austenite (γN), which can be produced during plasma nitriding of austenitic stainless steels, provides high levels of strength, toughness and corrosion resistance by comparison with traditional nitride layers. ...
A model of hard X-rays emission from free expanding Plasma-Focus discharges
(IOP Publishing, 2014-05)
A planar-piston model of the hard x-ray production in Plasma-Focus devices is presented. The model applies Von Karman approximations to represent the inner structure of the pinch. The hard x-ray emission is calculated ...
Expanded use of a fast photography technique to characterize laser-induced plasma plumes
(2015-07-29)
Expanded use of fast photography is proposed to characterize laser ablation plasma plumes by the analysis of a set of photographs by means of appropriate mathematical algorithms. The laser ablation plasma plumes studied ...
Structure and properties of low temperature plasma carburized austenitic stainless steels
(ELSEVIER SCIENCE SA, 2009)
Austenitic stainless steels cannot be conventionally surface treated at temperatures close to 550 degrees C due to intense precipitation of nitrides or carbides. Plasma carburizing allows introducing carbon in the steel ...
Study of modified area of polymer samples exposed to a he atmospheric pressure plasma jet using different treatment conditions
(2020-05-01)
In the last decade atmospheric pressure plasma jets (APPJs) have been routinely employed for surface processing of polymers due to their capability of generating very reactive chemistry at near-ambient temperature conditions. ...
Comportamento tribocorrosivo em liga austenítica AISI 316L modificada superficialmente a plasma em atmosfera livre de gás hidrogênio
(Universidade Federal de Minas GeraisBrasilENG - DEPARTAMENTO DE ENGENHARIA MINASPrograma de Pós-Graduação em Engenharia Metalúrgica, Materiais e de MinasUFMG, 2019-07-31)
In order to make feasible the use of austenitic stainless steels in applications
where high sliding wear and corrosion resistance are required, this work aimed
at the study of the surface modification of the AISI 316L ...
On the nitrogen diffusion in a duplex stainless steel
(São Carlos, 2015)
Duplex Stainless Steels (DSS) have excellent corrosion resistance properties and poor wear resistance. Plasma nitriding is used to increase the surface hardness, by nitrogen diffusion into the crystal lattice, and to improve ...
Surface analysis of alumina ceramic exposed to shock waves produced by plasma expander
(Iop Publishing Ltd, 2015)
Microstructure of nitrided and nitrocarburized layers produced on a superaustenitic stainless steel
(2013-01-01)
The expanded austenite γ<inf>N</inf> can be produced in austenitic stainless steels by plasma nitriding, carburizing or nitrocarburizing at low temperatures. This metastable phase presents higher hardness and toughness if ...
