“…In addition, it seemed difficult to obtain both the large toughness and high hardness of the tool coatings at elevated temperatures, which was very important for the cutting application. Recently, the multilayer coatings such as AlTiN/MoN, AlTiN/CrAlTiN [4], AlCrN/TiAlSiN [5], AlCrN/VN [6], AlCrN/AlCrON [7] have also been extensively investigated because of their superior tribological and mechanical properties under elevated temperatures. These multilayer nitride coatings have also demonstrated great ability to enhance the high-speed machining performance [8,9].…”

This study focuses on a comparative analysis of AlCrXN (X = Mo or V) coatings with the reference AlCrN coating via arc ion plating technique (AIP). The XRD and XPS results showed that the AlCrXN coatings were mainly composed of fcc-(Cr,Al)N solid solution phases. Both the AlCrMoN and AlCrVN coatings exhibited much higher hardness and adhesive strength than the AlCrN coating. The addition of Mo or V decreased the coefficient of friction (COF) and wear rate, which was due to the formation of lubricant oxides containing Mo or V on the coating surfaces. The cutting results showed that abrasive wear, adhesive wear, and oxidation wear were the main wear mechanisms for the coated tools at the cutting speeds of 60 m/min and 94 m/min. The addition of Mo or V dramatically improved the cutting performance of AlCrXN-coated tools by increasing the anti-wear ability due to the high hardness and the formed lubricant VOx or MoOx films.

“…Compared with the HVOF-sprayed coatings, the coatings produced by physical vapor deposition (PVD) reveal much higher surface hardness, compact structure and more excellent wear resistance [7][8][9][10]. However, due to its intrinsically brittle characteristic, thin thickness and high hardness differences between PVD coating and substrate, the PVD coatings reveal low load-bearing capacity and limit bond strength of coatings to substrate, which restrict PVD applications in some fields of more intensive loading conditions due to the plastic deformation of soft substrate [11].…”

Advanced HVOF-PVD duplex coatings were produced on the medium carbon steel by combinations of High Velocity Oxygen-Fuel (HVOF) and arc ion plating. The microstructures and mechanical properties were investigated by means of X-ray diffraction (XRD), scanning electron microscopy (SEM) in association with mechanical property measurement. The results show that the duplex coating are composed of an inner NiCr-Cr 3 C 2 -based HVOF-sprayed layer mainly consisted of γ-NiCr and Cr 3 C 2 phases, and an outmost PVD-AlCrN layer containing fcc-AlCrN phase. Duplex coatings reveal more excellent wear resistance when compared to the HVOF-sprayed coating. The improved wear resistance is mainly related to the outmost AlCrN layer with more excellent wear resistance in comparison to the

“…Magnetron deposition of metal-nitride/metal-nitride stacks, like in case of the TiAlN/CrN system as shown by Barshilia et al in 2005 [14], turned out more effective than simple alloying of chromium nitride, as they presented hardness as high as~38 GPa for the multilayer period of~7 nm. Later experiments done by Chen et al [9] showed that also the arc CrN/CrAlN/ (CrAlN/AlTiSiN) multilayer coatings could achieve comparable high hardness (~35 GPa) as long as a proper bias voltage sieving away at least part of droplets will be applied. Merging the knowledge from these experiments opened a field for development of coatings with bi-metallic multilayer nitrides from the Cr-Al-Ti-V system.…”

“…The latter requirement is hard to fulfill in practice with most PVD techniques, except magnetron or arc sputtering. The effectiveness of the arc technique is the highest, but on the other hand marred by its tendency for droplet deposition of diameter exceeding many times the nanolayers period [9,10]. The latter situation leads to local deformation of the nanolayers geometry compromising the coatings quality.…”

Molds made of tool steels used in aluminum high-pressure die casting should routinely withstand tens of thousands of injection cycles, but repeated loading and temperature spikes result in their frequent premature wear. Extending their lifetime could be sought by nitriding or application of coatings of even higher hardness or both. Therefore, in the present experiment the arc-deposited Cr/(CrN)/nx(CrN/CrAlN)/mx(CrAlN/VN) or Cr/(CrN)/nx(CrN/TiAlN)/mx(TiAlN/VN) nano-multilayer stacks were deposited on glow discharge nitrided X40CrMoV5.1 steel. The scanning and transmission electron microscopy backed by Energy Dispersive X-ray Spectroscopy measurements of local chemical composition helped to confirm that the coatings are built of nanolayers of respective nitrides of period less than 10 nm. They also showed that droplets being characteristic for arc deposition method were enriched either in chromium, aluminum or vanadium but not in titanium. Both coatings presented comparable hardness of ~25 GPa, but the one covered with TiAlN/VN was roughly twice as wear resistant as the CrAlN/VN. Simultaneously, they were ~200 and ~100 more wear resistant than X40CrMoV5.1reference steel.
