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.
Adhesión y desgaste de un recubrimiento PVD de TiN depositado sobre AISI 316L nitrurado
(2018-09-13)
En este trabajo se comparó la adhesión y el desgaste de películas delgadas de TiN con interfase
de Ti obtenidas por arco catódico combinado con implantación iónica (PBII&D), y de un
recubrimiento PVD TiN comercial, ambos ...
Influence of the silicon interlayer deposition process in the adhesion of the DLC coatings deposited on nitrided martensitic stainless steel
(2017-08-25)
The DLC coatings are characterized by good wear resistance, low friction coefficient and chemical
inertness [1]. However, they have adhesion problems when they are deposited on metallic substrates. For this reason, a thin ...
Microstructure and wear behavior of TiN coatings deposited on nitrided stainless steel by PBII&D
(2017-09-14)
This work presents the wear behavior of TiN coatings obtained by cathodic arc discharge combined with implantation and temperature on AISI 316L stainless steel previously ion nitrided.
Mechanical and corrosion behaviour of DLC and TiN coatings deposited on martensitic stainless steel
(2017-09-10)
The objective of this work is to compare the wear, friction, adhesion and corrosion behaviour of commercial TiN and DLC coatings deposited on AISI 420 stainless steel.
Comportamiento al desgaste y corrosión de un acero AISI 316L nitrurado y recubierto con TiN por PAPVD
(2017-10-18)
El objetivo de este trabajo es evaluar el comportamiento al desgaste, a la corrosión y a la erosión de recubrimientos comerciales de TiN depositados por PAPVD (Plasma Assisted Physical Vapour Deposition) sobre acero ...
Propiedades tribológicas y mecánicas de los recubrimientos en base carbono tipo DLC
(2017-08-17)
Los recubrimientos hidrogenados en base crbono tipo DLC (Diamond Like Carbon), son depositados sobre diferentes aceros y resultan atractivos por su excelente comportamiento tribológico, bajo coeficiente de fricción, alta ...
Wear and adhesion properties of a PVD duplex coated medium alloy steel for plungers in the oil and gas industry
(2017-07-05)
A duplex coating consisting in plasma nitriding of V820 steel (Boehler®) and a CrAlN coating (Balinit©, Oerlikon Balzers) was designed to enhance wear properties of hydraulic fracture pumps plungers used in the O&G Industry. ...
Extensión de durabilidad de pistones de bombas de fractura hidráulica mediante el empleo de tecnología de nitruración por plasma y PVD
(2017-05-10)
En la industria del Gas y del Petróleo (Oil&Gas), el concepto de fractura hidráulica consiste en romper la formación (reservorios) por intermedio de un fluído, básicamente formado por agua y arena que bombeado a una ...
Tribological behavior of thick and soft DLC coatings
(2015-05-13)
Austenitic stainless steels are widely used in industry due to their good corrosion resistance; however, they present poor mechanical properties.
Different coatings such as DLC “Diamond Like Carbon” can be used in order ...
