“…Due to the lower shear strength of V2O5 oxide than other oxides, the V-O containing tribofilm exhibited lower friction coefficient. Similar low friction has been found in binary VN coatings [37] where TiAlN, another constituent subphase in the TiAlN/VN, generally exhibits high friction [13,14]. The extremely low wear coefficient of TiAlN/VN can be explained in three aspects.…”

“…The research was performed on a recently developed lowfriction and wear-resistant hard coating, namely TiAlN/VN, being grown by combined cathodic arc and unbalanced magnetron sputter deposition. The TiAlN/VN is a multilayer nitride coating having nanometer-scale TiAlN and VN bi-layers, a NaCl-type cubic structure, and polycrystalline columnar morphology [13,14]. Its outstanding tribological properties, as compared to other hard nitrides in the TiN and TiAlN family, are the combined low dry sliding friction coefficient (= 0.4-0.6) and extremely low wear rate in a scale of 10 -17 m 3 N -1 m -1 [15,16].…”

A 20-50 nm thick tribofilm was generated on the worn surface of a multilayer coating TiAlN/VN after dry sliding test against an alumina counterpart. The tribofilm was characterized by applying analytical transmission electron microscopy techniques with emphasis on detailed electron energy loss spectrometry and energy loss near edge structure analysis. Pronounced oxygen in the tribofilm indicated a predominant tribo-oxidation wear. Structural changes in the inner-shell ionization edges of N, Ti and V suggested decomposition of nitride fragments.

“…In recent years, multilayer coatings have also been developed in an effort to tailor the properties of thin individual layers specifically to the application in mind [11]. For example, the use of CrN and VN based multilayers has led to "super-hard" surface coatings which, whilst very effective at resisting surface abrasion, can also adapt their surface properties under certain tribological conditions to yield desirable friction behaviour [12][13][14].…”

Nanoscale multilayer nitride coatings deposited by advanced PVD techniques have shown particular promise in improving the tribological properties of a number of modal alloy steels [1]. In this study, we report the effect of temperature on the friction and wear behaviour of a CrAlYN/CrN multilayer coating with a CrAlYON/CrON topcoat deposited on γ-TiAl. Deposition was performed by unbalanced magnetron sputtering following a high power impulse magnetron sputtering (HIPIMS) pre-treatment of the polished substrate. A series of pin-on-disc type experiments, sliding against a polycrystalline alumina counterpart, were carried out at four temperatures: 20ºC, 120ºC, 300ºC and 650ºC. An increase in the average steady-state dynamic friction coefficient was observed between the material couple, from 0.56 at room temperature to 0.65 at 120ºC. However at higher test temperatures of 300ºC and 650ºC a decrease in these values was observed to 0.59 and 0.40, respectively. Scanning electron microscopy and energy dispersive X-ray analysis showed evidence of oxidation at the worn surface of all test temperatures investigated, whilst laser confocal microscopy indicated the formation of an interactive tribo-layer above the plane of the original test surface. Focused ion beam sectioning has been used to prepare site specific samples of the tribo-layers for transmission electron microscopy. The evolution of the wear scar composition and structure and its influence on the reduction in dynamic friction coefficient at elevated temperatures is discussed.

Abstract. The aim of this work was to investigate mechanical and cutting properties, as well as the nature of wear and failure of carbide cutting tools with modifying coatings of two types: nanostructured multi-layered coating Zr-ZrN-(ZrCrAl)N, applied through the use of the technology of filtered cathodic vacuum arc deposition, and multi-layered nano-structured and gradient coating Ti-(TiAl)N-(TiAl)N, applied through the use of the technology of LARC ® (Lateral Rotating Cathodes). It is found out that the both types of coatings under test significantly improve tool life of a carbide cutting tool. The studies of mechanisms of wear and failure of carbide tools with coatings under test, conducted at macro and micro levels, have identified their major differences and revealed their most preferable field of application. The carbide tools, equipped with cutting inserts with the nano-structured multi-layered coating under study, provided a significant increase in cutting properties (tool life) of the tool in comparison with the uncoated carbide tool and in comparison with the reference carbide tool with TiN coating. The tool with the coating Ti-(TiAl)N-(TiAl)N under study demonstrated the increased wear resistance during 30-35 min of cutting, and then, the process of coating failure and tool wear was sharply intensified. For the tool with coating Zr-ZrN-(ZrCrAl)N, the tests revealed more evenly-balanced wear during the whole operating time between failures. It should be noted that NMCC Zr-ZrN-(ZrCrAl)N are substantially thinner, and that fact predetermines their better resistance to failure because of crack formation, and the technology of its generation is more cost-effective.
