“…Furthermore, it has been observed that sliding wear property of specimen depends on the counter face materials. These results are in agreement with many studies among others [24][25][26][27]. Under our tribological tests parameters, the (Cr/CrN/CrAlN)-PVD3 presents the lowest COF and also the lowest wear volume loss against alumina balls, while better tribological behavior is shown by the (Cr/CrN/CrAlN)-PVD1coupling against WC balls.…”

The application of these multilayers will be wood machining of green wood. That is why ball-on-disc and electrochemical tests in NaCl aqueous solution were realized to elucidate the tribological and corrosion behavior of these coatings as they will be exposed to wear and corrosion during wood machining process. The samples/alumina and samples/WC coupling showed different wear mechanisms. The 300 nm thick Cr/CrN/CrAlN multilayer demonstrated the best tribological behavior and corrosion resistance. The influence of growth defects on corrosion resistance has been shown. .

“…So in agreement with the literature [49], such differences against two different counterpart materials cannot be explained by only differences in hardness. Wear and friction is a systemresponse that depends on the composition, properties of the materials to be tested and also on those of the counterpart materials [12,[50][51][52]. The wear products (debris) play a key role in the tribological behavior of the couple in contact.…”

“…The wear products (debris) play a key role in the tribological behavior of the couple in contact. It was demonstrated [50] that the wear loss of the sample will be determined also by the size and shape of the hard particles presented in wear debris. So, the morphology of debris formed during the sliding of the coating against the counterpart material can reduce friction.…”

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.

“…However, several investigations [3][4][5] indicate that TA have poor friction and wear performance under extreme conditions of load, sliding speed, temperature and reversed thermal cycling environments, which has limited their applications. One of common methods of improving the friction and wear behavior of TA involves the uses of fillers in the past decades.…”
