Wear resistance of nitrided and DLC coated PH stainless steel
(2013-05-27)
In this work PH stainless steel Corrax(R) was ion nitrided and coated with DLC in a CVD process.
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.
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 ...
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. ...
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 ...
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 ...
DLC multilayers to improve fretting and corrosion resistance over nitrided martensitic stainless steel
(2018-09-20)
In this work, the fretting wear and corrosion behavior of DLC multilayers coatings were studied and compared to the monolayer coating.
