“…Relatively few reports can be found on ternary and quaternary coatings based on tungsten, although those reports have demonstrated good prospects for these material systems [14,15]. Tungsten carbide is of great interest due to its high melting point, superior hardness among other binary carbides and nitrides, low friction coefficient, considerable elastic modulus, small thermal expansion coefficient, and high thermal resistance.…”

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. a b s t r a c tTungsten carbide-based coatings have been used in a wide variety of industrial applications such as high speed cutting tools, extrusion dies, drills, aerospace industries, and more. A few reports on ternary and quaternary coatings of WC with other elements indicate good prospects for these material systems. The present study focuses on the formation of quaternary WCeCreN and WCeAleN coatings during the simultaneous reactive RF-magnetron sputtering of tungsten carbide and Al or Cr targets in an argon/ nitrogen gas mixture. The resulting coatings, with thicknesses of 3.5 mme8.2 mm, were characterized by using several analytical techniques including X-ray diffraction, SEM/EDS, AFM, and X-ray photoelectron spectroscopy. WCeCreN and WCeAleN coatings with high levels of tungsten (i.e. more than 50 at.% of the total metal content) demonstrated dense microstructure. Coatings with lower tungsten content formed columnar grain microstructure, with different surface morphologies depending on the process parameters. It was proposed that crystalline tungsten carbide (with partial N-substitution of C atoms) and chromium (or aluminum) nitride phases coexist in the coatings when the amount of tungsten was greater than 50 at.% of the total metal content; while at lower tungsten content, the dominating crystalline phase is either W-doped CrN 1Ày or AlN 1Ày solid solution, with WC 1Àx and small amounts of free sp 2 -bonded carbon present as X-ray amorphous phases.

“…The M 7 C 3 carbides eventually grow as rods and blades, in a direction such that their long axes are parallel to the direction of heat flow. On the other hand, the microstructure of these surfaces must also be well characterized after being coated, because the wear-resistant surfaces are typically used in surfaces coated with thin layers of alloys [5]. Some investigations revealed the effects of conducting a process of solidification on the microstructure that contained 10 wt.% Cr alloys [6][7][8][9] and studied the relationship between the structure and the toughness of the fracture.…”

Surfaces that are coated with steel are considered useful for grinding and milling applications based on their ability to resist abrasions. In the present study, the microstructures of hypoeutectic, eutectic, and hypereutectic compositions in 10-20 wt.% chromium (Cr) samples were studied with respect to the micro-structural transitions of the coatings and several other processing parameters. In addition, tests were conducted in order to analyze the influence of the microstructure of the coated surfaces on the capacity of the hypoeutectic, eutectic, and hypereutectic Cr-enriched microstructures of the samples coated with 10-20 wt.% Cr alloy to resist wear. Consequently, it was found that based on the presence of an austenitic matrix within them, the coated regions effectively resisted abrasions.
