Sažetak

The paper presents the results of studying microhardness and tribological characteristics of antifriction cast iron grade AChS-3 after modification with titanium carbide. Titanium carbide has been used as a nanomodifier to change the structure parameters by forming additional crystallization centers. It has been established that introducing titanium carbide in the amount of 0,2-0,3 % by weight with dispersion of 0,3-0,5 μm leads to increasing its hardness and wear resistance by about 20 %, while the friction coefficient decreases by almost 2 times.
