Tribological behaviour of a multilayer CrN/DLC coating obtained using PVD-MS
(2022-08)Diamond-like Carbon (DLC) coatings are used as protective layers for steel components due to their hardness, chemical inertia and interesting tribological properties. Reducing wear and friction coefficient is of great ... -
Near superhydrophobic carbon nanotube coatings obtained via electrophoretic deposition on low-alloy steels
(2021-01-20)Sucker rods are a key element in certain oil-extraction processes as they link the motor group on the surface with the pumps located downhole. During the transport from the production site toward the extraction well, these ... -
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 ... -
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 ... -
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 ... -
Carbon based DLC films : influence of the processing parameters on the structure and properties
(2018-07-19)Hydrogenated carbon-based films, such as DLC (“Diamond Like Carbon”), have interesting properties such as excellent tribological behavior, low friction coefficient, high superficial hardness and good wear resistance; they ... -
Comparación del comportamiento al desgaste de un acero AISI 1045 nitrurado y seguido de un temple por inducción
(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 ... -
Influence of the pre-treatments and process temperature on the adhesion of TiN films deposited by PBII&D over nitrided austenitic stainless steel
(2019-10-28)In this work the influence of pre-treatment cleaning processes in the adhesion of TiN films deposited by the plasma based ion implantation and deposition (PBII&D) process over plasma nitrided AISI 316L stainless steel was ... -
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 ... -
Tribological and corrosion Behavior of Duplex Coated AISI 316L using plasma based ion implantation and deposItion
(2020)The implementation of a duplex process, which combines plasma nitriding with hard coatings obtained by cathodic arc, on stainless steel substrates has faced adhesion problems that affected the wear and corrosion behavior ... -
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 ... -
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. ...
