“…Whereas, load, sliding speed, and sliding distance were chosen as input parameters [58,71,72]. The sliding wear parameters range were selected as load: 10-50 N; sliding distance: 500-1,500 m; sliding speed: 0.5-1.5 m/s, based on previous literature [29,39,44,58,70,73]. Further, five levels of each factor were calculated as per the central composite design based on the rotability value (α = 1.682), which was obtained using Minitab 19 software (detailed discussion in experimental design section) [62,73,74].…”
