“…8) with the aim of estimating the spreading properties employing data from both surface and liquid. (8) There are two opposite phenomena related to the wetting of a surface: when contact angle is timedependent and SP>0 (spreading-wetting) or when cohesion work between molecules of the ionic liquid is greater than work of adhesion on the solid-liquid interface provoking a constant contact angle and SP<0 (adhesion-wetting). However, tribology studies usually do not use this approach despite of the fact that knowledge of wettability parameters could help to properly design lubrication systems [62,63].…”

The wetting and corrosion behavior of three bis(trifluoromethylsulfonyl)imide-based ionic liquids: 1-Dodecyl-3-methylimidazolium bis (trifluoromethylsulfonyl) ]/TiN resulted as the best IL-surface combination for a good wettability, due to the higher dispersion of the charge on the large size cation in this IL and the higher values of total and polar component of the surface free energy for this coating. Finally, SEM-EDS analysis determined that [N 1888 ][NTf 2 ]/ZrN was the best option in order to avoid corrosion problems. The evaporation of water, present as impurity in the ionic liquids, was found the main reason because of corrosion did not occur in the tests carried out at 100 ºC.

“…5(a-b)). Zone B (the transition stage) corresponds to an increase of the COF that is mostly due to an increase in the frictional force, as the counterpart deforms and fractures [45,46]. Once the asperities are smoothed out, zone C corresponds to the last~2000 cycles.…”

is an open access repository that collects the work of Arts et Métiers ParisTech researchers and makes it freely available over the web where possible. The objective of this work is to study the improvement of the tribological properties of low alloy steel using a duplex treatment of low pressure carburizing and the deposition of a Cr-(WC-Co) coating by dual RF magnetron sputtering. The treatments result in a 500 μm thick carburized layer and a sputtered coating thickness of~2 μm. Tribological tests were made with a ball-on-disk tribometer under dry conditions with low load and low speed. The worn surfaces of the disk, the wear counterpart, and resulting debris were analyzed by X-ray diffraction, optical microscopy, optical profilometry, and a scanning electron microscope equipped with an energy-dispersive X-ray spectrometer. The wear performance of the samples was evaluated in terms of wear rates and friction coefficients during the sliding processes against two different counterparts. Experimental results have shown that sliding wear, of the investigated duplex treated low alloy steels, is strongly dependent on the counterface materials. Under testing conditions, the overall wear performance of a Cr-WC coating (Cr/W ratio of 1.12:1) deposited onto the surface of a carburized low alloy steel (0.61 wt.% C; HV = 654 ± 5) can be recommended as the best. The duplex-treated samples suffered severe, concentrated wear when against alumina. This wear is characterized by a combination of delamination, mild abrasion and oxidative wear. However, the wear mechanism seems to be oxidative and adhesive when against WC balls.

“…In the running-in stage, the friction force is mainly contributed to deform and fracture the contact asperities [25]. Due to the lower hardness of the coating material at higher tested temperature, it would take less number of cycles for the friction coefficient to reach the steady stage.…”

Abstract:The combination of high temperature indentation and wear test provides a useful way to investigate wear of CrN coating and wear transition mechanisms. In this paper, the high temperature hardness of CrN coatings and load bearing capacity, L b , of CrN coated M50 disks were determined from spherical indentation at temperatures up to 500 • C. Wear tests with different normal loads were carried out at the same temperatures as the indentation tests. The results show that wear mechanism of CrN coating changes with external load, P, and temperature, T. Under a tested condition of P < L b and T < 315 • C, abrasive is the dominant wear mechanism for CrN coating. Under a tested condition of P < L b and T ≥ 315 • C, wear of CrN coating transitions into mild oxidation wear due to the lubricating effect of chromium oxide film. Under a tested condition of P > L b and T < 315 • C, wear of CrN coating was controlled by coating fracture. Under a tested condition of P > L b and T ≥ 315 • C, wear of CrN coating transitions into the severe wear mode, due to the tensile fracture of oxidation films, thereby leading to adhesion between CrN coating and tribo-counterpart. The presented method can be helpful in predicting permissible load and working temperature in tribological applications of CrN coating.
