. Second, the wear loss of the enamel in the citric acid solution
was about 2.5 times higher than that obtained in the artifi cial saliva under a low load
of 10 N, but the wear loss gap between the two wear media became smaller as the
normal load increased, as shown in Figs.
4.9
and

. Based on the observations, it
could be inferred that the wear mechanism of enamel in the citric acid solution var-
ied with the normal loads. As shown in Fig.
