“…Furthermore, the CrAlN layers present a high coefficient of friction (0.6-0.75) as observed in a previous study [13]. Brizuela et al [14] showed that the friction coefficient of CrAlN coatings varied between 0.42 and 0.55 during pin-on-disc tests applying a load of 0.98 N to an AISI 52100 steel ball of 10 mm diameter, at a constant sliding speed of 0.1 m/s under controlled humidity of 50%. However the coefficient of friction stays below the substrate one of 1.0 which was determined with pin-on-disk on a sample with a high roughness (Rt close to 1 m).…”

Nevertheless, even if this material is homogeneous, it is abrasive enough to tend to the breakdown of the conventional carbide tools employed during its routing process. That is why it is necessary to improve the wear resistance of these tools. One solution is to protect them with a hard coating.The present study deals with the development of ternary CrAlN hard layers obtained by PVD method on carbide tools employed in second transformation of wood. CrAlN coatings have been optimized and then applied on carbide tools in routing of three types of MDF: standard, waterproof and fireproof. The aim of these wood machining tests was first to define the ability to be machined of the three kinds of MDF and second to compare the effectiveness of CrAlN coatings during the routing tests of these materials.

“…In a previous work we also confirmed the improved oxidation resistance of a CrAlYN coating in comparison to CrAlZrN [24]. The tribological properties of CrAlN coatings have been investigated previously [6,7,[25][26][27] but only limited information is available about their tribological behavior at high temperature [28][29][30]. Other studies have explored the enhancement of tribological properties by alloying carbon or vanadium that promote the formation of lubricant tribo-layers [31,32].…”

“…And, a high hardness ($ 30 GPa) and a high oxidation resistance temperature (900 1C) were reported for CrAlN coatings [5]. The effect of Al concentration in the Cr-Al-N system on its mechanical properties (hardness, elastic modulus, adhesion, oxidation…) as well as different wear behaviors has already been reported [6][7][8].…”

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 tCrN/CrAlN and Cr/CrN/CrAlN multilayers were grown with dual RF magnetron sputtering. 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. .
