5.1 Appendix 1: Wear analysis of copper dihedrals using extruded burrs

The results shown in figure 7 for contact between a steel disc and a copper pin correspond to wear under initially high contact pressure. It is interesting to see whether this wear follows the Preston-Archard law.

We can plot the evolution of the copper wear volume V = (1/4)bl 2 cotθ as a function of the sliding length L = 2π RN (figure
