Erosion resistance of engineering ceramics and comparative assessment through Wiederhorn and Evans equations

Resistance to erosion is one of the most desirable characteristics of materials that must undergo a tribological interaction, where engineering ceramics play an important role given their intrinsically enhanced mechanical properties. The fracture toughness and hardness of Al2O3 (alumina), ZrO2 (zirconia) and Si3N4 (silicon nitride) were compared with their erosion rate when subjected to solid particle jet wear from different incidence angles...
