OBRABOTKAMETALLOV MATERIAL SCIENCE Vol. 27 No. 2 2025 a b c Fig. 10. Comparison between experimental and simulation results (a) material M1 (b) material M2 (c) material M3 – Numerical simulations using Archard’s wear model closely aligned with experimental results, particularly for M2, with deviations of less than 10 % under moderate conditions. However, M3 showed a 10–15 % overestimation in wear predictions, while M1 displayed larger discrepancies due to its thermal softening under higher loads and temperatures, highlighting the importance of material reinforcement. – Material M1, possessing the lowest wear resistance, exhibits high sensitivity to load and temperature due to its poor mechanical strength. Material M3 demonstrates moderate wear characteristics; however, its specific wear rate significantly exceeds that of M2 under extreme conditions. Material M2, characterized by superior load-bearing capacity, thermal stability, and consistent performance, is the most promising material for high-stress tribological applications. Optimization of operating parameters, involving maintaining a load of 160 N, a sliding speed of 451 rpm, and a temperature of 130 °C, minimizes wear and validates the effectiveness of empirical models for predicting the tribological behaviour of materials.
