Comportamiento al desgaste de un acero SAE 1045, templado por inducción posterior a la nitruración iónica : películas delgadas y tratamiento de superficie
(2015-11-17)
Los aceros al carbono son ampliamente utilizados en la industria metalmecánica en los componentes de las maquinarias; esto se debe a que se puede mejorar sus propiedades: como obtener alta dureza y tenacidad a un costo ...
Carbon based coatings deposited on stainless steel : study of thermal degradation
(2017-03-02)
Amorphous hydrogenated carbon (DLC) coatings have a high hardness depending on the relative amount of sp3/sp2 bondings. They also exhibit an extremaly low friction coefficient and are chemically inert. However, these ...
Protección de acero para instrumentos quirúrgicos con recubrimientos duros en base carbono tipo DLC
(2018-07-19)
Los aceros inoxidables martensíticos como el AISI 420 tienen múltiples aplicaciones, entre ellas instrumentos quirúrgicos, donde se requiere buena resistencia al desgaste
y a la corrosión. Los tratamientos de modificación ...
Characterization of DLC coatings over nitrided stainless steel with and without nitriding pre-treatment using annealing cycles
(2019-04-02)
Amorphous hydrogenated diamond-like carbon (DLC) coatings were deposited using plasma assisted chemical vapour deposition (PACVD) on precipitation hardening (PH) stainless steel. Plasma nitriding has been used as ...
Comparación del comportamiento al desgaste de un acero AISI 1045 nitrurado y seguido de un temple por inducciónComparison of behaviour wear of nitrided and induction hardened-nitrided aisi 1045 steel
(2016-10)
Se estudió el comportamiento al desgaste del acero AISI1045 con un tratamiento de nitruración iónica y posterior temple por inducción. Se midió dureza en superficie y perfil en profundidad. Se analizó la microestructura y ...
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 ...
Fretting wear resistance of DLC hard coatings deposited on nitrided martensitic stainless steel
(2019-03)
In this work, the fretting wear behavior and adhesion of DLC coatings deposited by PACVD on nitrided and non-nitrided martensitic stainless steels were studied. Fretting wear tests were carried out with different duration ...
Contact fatigue behavior of α-Al PROOF 2 O -Ti(C,N) CVD coated WC-Co under dry and wet conditions
(2020-11-07)
The response to cycling contact fatigue load of a WC-6%Co carbide coated with a Ti(C,N)/α-Al2O3 CVD multilayer was investigated in dry and wet conditions. Imprints in dry conditions were characterized by small thin ...
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. ...
Soft and thick DLC deposited on AISI 316L stainless steel with nitriding as pre-treatment tested in severe wear conditions
(2020)
Thick and soft DLC coatings were deposited over stainless steel to improve their surface properties, protecting them from wear in different conditions. When a protective film is thick, it can be considered as selfsustaining ...
