Material M2 performed better than M1 and M3 when the load and speed were incremented. At a 25 N load and 1,000 rpm, M1 showed the highest volume loss of 185.1592 mm3, followed by material M3, which showed a volume loss of 123.9012 mm3. Meanwhile, M2 showed the lowest volume loss of 18.0080 mm3 with a specific wear rate of 3.7094E-05 mm3/N×m. The consistency of the data obtained from the center point replicates (Runs 15-20) validates the reproducibility of the experimental methodology. The average specific wear rate of M2 at the center point was 2.108E-05 mm³/N×m, lower than that of M1 (1.238E-04 mm³/Nm) and M3 (8.814E-05 mm³/Nm). The value of the correlation coefficient (R2 value) obtained was 0.91, 0.96, and 0.93, indicating that the empirical expression developed (shown in Table 6) would be effectively suitable to understand the wear
