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 ...
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 ...
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 ...
Influencia de los parámetros de nitruración iónica de corta duración en la resistencia al desgaste de un acero AISI 420 : películas delgadas y tratamientos de superficie
(2015-11-17)
Los aceros inoxidables martensíticos son frecuentemente utilizados en la industria petroquímica e hidráulica y toda aquella donde se requiera un acero inoxidable con buenas propiedades mecánicas y alta resistencia al ...
Plasma nitriding plus oxidizing as a protective treatment for AISI 4140 steel
(2022-09-29)
AISI 4140 is a typical chromium molybdenum medium alloy steel, widely used as construction steel for machine components. Plasma nitriding has been applied as surface hardening treatment with success but the nitrided layer ...
