“…Several mechanisms have been proposed to clarify how material is removed from the surface of WC based hardmetals during sliding wear [17,26,[34][35][36]. In general, friction and wear is believed to result from three components: abrasive ploughing, adhesion and asperity deformation.…”

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.

“…Several studies have been carried out in order to first understand the different mechanisms contributing to cutting edge wear of tungsten carbide tools during MDF machining [1,2], second to improve tool life using hard coatings [3,4], cryogenic treatment [5] or different kinds of tungsten carbide [6]. Nevertheless, no study has been conducted to define the machining ability of different types of MDF.…”

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.

“…In the initial stage of wear, Cu matrix as well as the binder between SiC reinforcement particles is removed by plastic deformation and microabrasion [11] . The worn debris is oxidized to form Cu 2 O and CuO and deposits on the wear trace.…”
