This study describes the correlation between the microstructure, mechanical and tribological properties of Ti1-xCx coatings (with x being in the range of 0-1), deposited by reactive magnetron sputtering from a Ti target in Ar/C2H2 mixtures at ~200 °C. The mechanical and tribological properties were found to strongly depend on the chemical composition and the microstructure present. Very dense s...

Water can be used as an ecological lubricant base if it is possible to select additives which can beneficially modify its tribological and corrosion properties. Additionally, those additives should not be harmful to human health and the natural environment. These conditions limit or even eliminate the possibility for the application of the additives used in traditional oil bases as they are ins...

Carbon-based systems comprise an impressively broad and continually expanding range of materials, from the building blocks of biology to carbon allotropes with extreme and exotic properties such as nanotubes, buckyballs, graphene1, and diamondoids2. The myriad of stable forms that carbon can adopt is largely because of its ability to hybridize in multiple stable bonding states, and to bond stro...

Tribology deals with parts in relative motion, and related friction, adhesion, lubrication and wear phenomena. With our devices getting smaller and smaller, our understanding of tribology on the small scale has to increase. Microand nanotribology denotes tribology performed with microand nanotechnological instruments. This field is still in a developmental stage, and establishing the relation a...

Transition metal chalcogenides with lamellar structure are known for their use in tribological applications although limited to vacuum due to their easy degradation in the presence of oxygen and/or moisture. Here we present a tailored WSex coating with low friction (0.07) and low wear rates (3×10(-7) mm3 Nm(-1)) even in ambient air. To understand the low friction behavior and lower chemical rea...

Titanium nitride thin films are used in applications such as tribological layers for cutting tools, coating of some medical devices (scalpel blades, prosthesis, implants etc.), sensors, electrodes for bioelectronics, microelectronics, diffusion barrier, bio-microelectromechanical systems (Bio-MEMS) and so on. This work is a comparative study concerning the influence of substrate temperature on ...

The mechanical and tribological properties of electrospun fiber mats are of paramount importance to their utility as components in a large number of applications. Although some mechanical properties of these mats have been reported previously, reports of their tribological properties are essentially nonexistent. In this work, electrospun nanofiber mats of poly(trimethyl hexamethylene terephthal...

A novel negative, inorganic polymer photoresist was demonstrated to be suitable for simple and direct fabrication of tribological SiCN-based ceramic microstructures via UV photolithography and subsequent pyrolysis at 800 degrees C.

aluminum alloys such as al 5083 have primary potential for lightweight structural application in automotive and aerospace industries. this paper addresses the mechanical and tribological properties and corrosion resistance of chromium nitride coatings deposited on al 5083 that can be used for development of applications of aluminum 5083 alloy. the crn coatings of 1 μm thickness were deposited b...

The aim of the present work is to determine the influence of technologically produced boron surface layers on the friction parameters in the sliding pairs under mixed friction conditions. The current boronizing processes allow obtaining surface layers of high hardness and high resistance to corrosion and wear, with low brittleness and no tendencies towards cracking However, the operation charac...
