Purpose: The article presents the research results on tribological properties (friction coefficient, wear) of the frictional couple cast iron-composite. The subject of that research was aluminium heterophase composites containing two carbide phases: chromium (Cr3C2) and titanium carbides (TiC). Design/methodology/approach: The friction process was conducted on a tribological pin-on-disc tester (T-01M) under technically dry friction conditions. Findings: The results of friction and wear coefficients’ investigation allowed the determination of how the volume fraction of NiCr/Cr3C2+TiC composite powder can influence on the course and degree of cast iron and composite wear. Practical implications: An increase in the reinforcing phase fraction allowed the elimination of the phenomena connected with adhesion wear. The 10% fraction of a carbide reinforcing phase ensures a uniform wear mechanism and has a beneficial influence on the operation of the tribological couple: cast iron - heterophase composite, during which no negative effects of increased wear of the cooperating material are observed. Originality/value: The application of heterophase reinforcement is a solution which to a large extent enables the broadening of the possibilities to design and diversify the tribological properties of friction couples.
