This work shows a study of the tribological and corrosive behaviour of AISI 4140 steel previously quenched and tempered, plasma nitrided and then coated with CrN thin film, in contact with hydrated ethanol fuel. The ...

One of the purposes of surface engineering is to combine physical-chemical, tribological and mechanical properties of materials aiming high hardness, low friction coefficient and high wear resistance, associated with ...

In this work, amorphous hydrogenated carbon (a-C:H) thin films were deposited using a simple, low cost and efficient pulsed DC - plasma-enhanced chemical vapor deposition technique improved by electrostatic confinement ...

The deposition of thin films can be employed to modify and/or functionalize the properties of a material’s surface, improving wear resistance (tribological properties) or changing the resistivity (electrical properties). ...

This work studies the deposition of titanium nitride (TiN) thin films on stainless steel AISI 304 substrate for decorative applications. The films studied here are composed of a layer of Ti working as an interlayer between ...

The diamond-like carbon (DLC) thin films family, in particular hydrogenated amorphous carbon films (a-C:H) have interesting properties for academic and technological purposes. High wear and ultra-low friction can be found ...

Ibuprofen is an anti-inflammatory with an annual production of more than 15 thousand tons, whose concentration in aquatic ecosystems reaches the order of tens of μg L-1. The degradation of this emerging pollutant and other ...

The use of cutting tools in progressively more severe conditions in the metal-mechanics industry and the requirement to increase tool life against friction, wear and high temperature corrosion made of surface treatments ...

Nanotechnology has brought some new challenges such as the development of quality and synthesis processes on nanostructures based on inorganic and organic substances. The development of new materials with organic and ...

Hard coatings are widely used in surface engineering of mechanical components due to their high wear resistance and reduced friction coefficients. Actually, the dry cutting techniques are demanding new materials with ...
