Mass loss and wear mechanisms of HVOF-sprayed multi-component white cast iron coatings

► Multi-component white cast iron was applied by HVOF as hardfacing. ► Effects of pre-heating and heat treatment of coating on mass loss were determined. ► Influence of heat treatment of coating on wear mechanisms was also determined by SEM. ► Heat-treated coatings presented mass loss three times lower than as-sprayed coatings. ► Wear mechanisms are micro-cutting associated with cracks close to unmelted particles.
