Figure 2
A line graph showing the variation of the wear coefficient with sliding distance and time. The x axis represents sliding distance as a function of time, ranging from t equals 0 to t equals T over 2. The y axis represents the wear coefficient. The graph shows a single line that starts at the origin, rises to a peak labeled K act, and then falls back down, intersecting a horizontal dashed line labeled K ave. All values are approximated.Variation of the wear coefficient with sliding distance and time. Source(s): Hanief and Charoo (2021)
