“…The Al content contained in CrAlN films varies between 5 and 51 at.%. We can note that in the CrAlN deposited films, the hardness varies between 15 and 36 GPa which is more than the conventional Cr-N system [9] or the WC-Co substrate (16 GPa) [10]. Besides, a high Young modulus (which varies between 331 and 520 GPa) has been calculated (same results were obtained by Kim and Lee [11]), which is good for an application of these layers on WC-Co substrates which have a Young modulus of 640 GPa [12].…”

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 tNowadays, medium density fibreboard (MDF) composite wood is more and more used in the furniture industry to replace bulk wood such as oak, beech, etc. Indeed, this material presents good mechanical properties, is easy to machine, homogeneous, exists in different dimensions (thickness, etc.), is cheaper than bulk wood and finally can be covered by an adhesive decorative coat. 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.

“…Furthermore, hardness, toughness and strength characteristics can be tuned by adding an adequate amount of metal binder during the liquid-phase sintering process, as mentioned by e.g. [18][19][20][21][22][23]. The superior properties obtained with cobalt bound materials have made this metal the most commonly used binder.…”

Dry Reciprocating Sliding Friction and Wear Response of WC–Ni Cemented Carbides

A number of WC-Ni based cemented carbide grades with distinctive binder contents were tested with the goal to evaluate their dry reciprocating sliding friction and wear behaviour against WC-6 wt.%Co cemented carbide using a Plint TE77 tribometer and distinctive normal contact loads. The generated wear tracks were analysed by scanning electron microscopy and quantified volumetrically using surface scanning topography. The experimental results revealed one WC-Ni grade with superior wear performance.

“…In general, wear rate decreases as hardness is increased, i.e., as the amount of metallic binder and the average carbide grain size are decreased. Figure 6.18 shows the experimental dependence of hardness and K a with the binder content, for a WCCo hardmetal with a carbide grain size of around 1 μm, dry sliding against steel (H: 200 kg/mm 2 ) [44]. It has been observed that wear was characterized by the progressive removal of the cobalt binder, accompanied by the brittle fracture and fragmentation of the carbide grains.…”
