Resistance of Cemented Carbides to Sliding Abrasion: Role of Binder Metal

  • Jorn Larsen-Basse


Cemented carbides of the WC-Co, WC-FeNi and TiC-MoNi families were studied. Laboratory abrasion test results for hard and soft abrasives were compared with SEM studies of removal mechanisms and with hardness and Palmquist crack resistance data.

In wear by hard abrasives material is removed from the wear surface by a mechanism involving gross plastic deformation due to yielding and extrusion of binder metal and/or by a mechanism of spalling due to crack propagation in the binder metal. In wear by soft abrasives material is removed by a series of microprocesses involving extrusion of binder followed by relaxation of compressive stresses in the carbide grains and subsequent cracking and fragmentation of these grains. In systems where the diffusion or mechanical bond between binder and carbide is weak whole grains may be pulled from the wear surface. In systems where a strong diffusion bond exists between the two phases material may be removed by brittle spalling due to cracks propagating through both phases. Under some wear conditions binder metal may be smeared back onto the wear surface. In the case of cobalt this may provide a lubricating, wear reducing effect.
