Resistance to abrasive wear of Ni3Al - based intermetallic alloy with the alloying additions of Zr and B was investigated using "pin-on-disc" method at room temperature. It has been found that abrasive wear resistance of investigated alloy strongly depends on a degree of homogenisation of its structure (predominantly chemical homogenisation and probably a level of ordering) and does not depend on a shape and size of crystallites/grains in their structure. Samples with structure modified by homogenisation treatment or by cold rolling followed by recrystalization showed excellent wear resistance in opposite to as-cast or cold rolled condition. Even though cold working significantly increases (doubled - in comparison to as-cast condition) level of Ni3Al alloy hardening, an abrasive wear resistance for this case is the lowest among all investigated samples. Finally a relationship: the highest hardness of Ni3Al alloy the lower its abrasive wear resistance was observed.
