Abstract
Tribology has been a problem with the global industrial scenario. Some billions of dollars are lost every year arising for this, United states show a study that 2% of his gross national product are lost , as well as England and Germany that lost 1% and 2.5% of GNP respectively. The carbon-based coatings could be an alternative to mitigate wear and improve lubrification in this scenery. The oil and gas industry has suffered from this problem, leading impurities and containing the oil. As a result leaks and corrosion damage this industry sector. In this project, the goal is to investigate the tribology behavior of the carbon-based coatings, deposited on AISI/SAE 4140 steel, obtained by three different deposition technique: PIID (Plasma Immersion Ion Deposition), HiPIMS (High Power Impulse Magnetron Sputtering) and PIID+PEMS (Plasma Enhanced Magnetron Sputtering). Nitrided and non-nitrided samples were investigated to compare the three different techniques. Adhesion evaluation and characterization of this DLCs were investigating too.
