The improvement of hard facing coatings for ground engaging applications by the addition of tungsten carbide

Wear resistance was measured using several techniques; micro-scale abrasive wear (MASW) using SiC and SiO2 abrasives and rubber wheel tests using sand abrasive in both dry and wet conditions. A correlation between the size of the hard addition and the size of the abrasive particle was observed and significant improvements in wear resistance due to the presence of the WC is demonstrated.
