Tungsten Carbide Cutting Tools Abrasive Wear

Process of tungsten carbide cutting tools abrasive wear in detail can be devided into the following steps: a surface layer bonded tungsten carbide cuttingtools with mobile; increase grain plastic strain;; plastic deformation fracture binder phase single grain; grain between fracture; grain pull out from the base.

Under different experimental conditions, the degree of tungsten carbide cutting tools abrasive wear appears different. For example, tungsten carbide cutting tools in a smaller case load is much less abrasive wear than that in the case of large pressure.



In the initial phase of tungsten carbide cutting tools abrasive wear, the binder phase material contacts the inner surface of a certain depth range of Co plastic deformation and micro-abrasion in the role of friction surface Co is out from between the WC grains. With the loss of Co binder phase, surface damage the integrity of  tungsten carbide cutting tools, WC skeleton becomes unstable, cracks between the WC grains, so that part of the particles start to pull out from the surface of the substrate. When the friction surface is extruded and Co and WC particles reach a certain number, abrasion enter a relatively balanced steady-state level. In this case, loss of WC particles begin to appear in the form of abrasive grains, laminated in the outside world, the formation of tungsten carbide cutting tools abrasive wear.
