Two-body and three-body abrasive wear tests of katsura wood were carried ou
t using abrasive paper and moving abrasive grains, respectively. The two-bo
dy and three-body abrasive wear properties were investigated and compared.
The wear rate of two-body abrasive wear was two orders of magnitude larger
than that of three-body abrasive wear. Moreover, two-body abrasive wear of
katsura wood increased with higher applied surface pressure, whereas three-
body abrasive wear did not always depend on the applied surface pressure. B
ased on these results and observation of the wear surface profiles, it is s
uggested that. two-body abrasive wear is more affected by yield stress and
surface microstructure, and three-body abrasive wear is more affected by th
e cutting action of moving abrasive grains. Furthermore, during wear tests
with different abrasive grain sizes, critical grain size effects of two-bod
y abrasive wear were observed at low applied surface pressures but not at h
igh applied surface pressures. The critical grain size effects of three-bod
y abrasive wear were observed at both low and high applied surface pressure
