Plasma surface engineering to enhance wear and corrosion resistance of stainless steels
(2014-11-11)
A brief description of the research lines of the Surface Engineering Group of UTN will be presented, as well as some important results obtained in the last years concerning plasma nitriding of austenitic stainless steel ...
Influencia de la nitruración por plasma sobre el comportamiento a la corrosión y la adhesión de recubrimientos DLC sobre acero inoxidable AISI 420
(2016-04)
En este trabajo se estudió el comportamiento a la corrosión y la adhesión de dos recubrimientos DLC (“Diamond Like Carbon”), “Soft” y “Hard”, depositados por PACVD (“Plasma Assisted Chemical Vapour Deposition”) sobre acero ...
Corrosion behaviour of a SiOxNy coated and nitrided ph stainles steel
(Elsevier, 2015)
Precipitation hardening stainless steels are used in applications where wear and corrosion resistance are required. To improve the surface properties, thermochemical treatments in combination with hard coatings can be used. ...
Plasma nitriding and plasma nitrocarburizing of a low alloy steel selected to produce camshafts for diesel engines
(2015-05-14)
Camshafts are a relevant part of diesel engines of extended use today. These components work under torsion and are also prone to fatigue and wear damage. Usually they are manufactured by casting, forging or machining from ...
Characterization of thick and soft DLC coatings deposited on plasma nitrided stainless steel
(2014-09-15)
Thick and soft DLC coatings were deposited by PACVD with a DC pulsed discharge on nitrided and non nitrided austenitic stainless steel. The films were characterized by EDS and Raman, hardness was assessed with nanoindenter ...
Comportamiento a la corrosión de un acero endurecible por precipitación nitrurado y recubierto con SiOxNy
(2013-08)
Los aceros inoxidables endurecibles por precipitación (PH) son utilizados en aplicaciones donde se requiere resistencia al desgaste y a la corrosión. Para mejorar las propiedades superficiales se pueden combinar tratamientos ...
Corrosion resistance of AISI 316L stainless steel nitrided by three different plasma assisted techniques
(2014-07-23)
Plasma assisted surface modification methods have been used to nitride stainless steels in order to enhance and therefore the lifetime of industrial components. Nevertheless, the corrosion resistance is not always preserved ...
Laser texturing combined with plasma nitriding as a tool to control the tribological performance of steel components
(2018-09-28)
In this work the sequential combination of both plasma nitriding and laser patterning is analyzed
comparing to individual treatments over the same material.
Development of a post oxidizing process over nitrided medium alloy steels for wear and corrosion protection in oil sucker rod lift
(2018-09-28)
To study this surface treatment, AISI 4140 polished PPD prototypes were nitrided, in a DC Plasma industrial equipment, and then were oxidized in the same chamber. Witness specimens were also treated and analyzed in the laboratory.
Development of a post oxidizing process over nitrided and nitrocarburized steels for wear and corrosion protection
(2018-09-20)
The environmental concern on the use of this coating stimulated the research activities for alternatives of hard chromium. In this work, AISI 1045 was nitrocarburized, AISI 4140 was nitrided, both in a DC Plasma industrial ...
