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 ...
Influencia de la rugosidad superficial en el tratamiento de nitruración y post oxidación del acero AISI 4140
(2021-10-05)
Los aceros de media aleación son muy utilizados para fabricar elementos de máquinas dadas sus buenas prestaciones mecánicas, aunque suelen presentar un coeficiente de fricción elevado, aun con tratamiento térmico. Para ...

Este trabajo describe el resultado de una experiencia exitosa de vinculación de Universidades con Empresas, tanto grandes como PYMES, y el Estado. Este esfuerzo conjunto concluyó con la obtención de un PID de la Agencia y ...
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. ...
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 ...
Evaluation of a multilayer Cr/CrN with DLC as top coating obtained using PVD
(2021-11-18)
In this work, a multilayer Cr/CrN plus DLC as top coating which was deposited by means of MS-PVD
Plasma Enhanced Magnetron Sputtering on nitrided and non nitrided mild alloy steel AISI 4140 (DIN
42CrMo4) is analyzed.
