Abstract
High strength steels (HSS) used in highly abrasive
environments, such as in mining and crushing, must endure
high stress abrasion. To properly understand the wear
behavior of materials under such circumstances, the
connection between surface loading, work hardening, and
material removal has first to be determined. In this
study, wear resistant steels with initial hardness
ranging from 400 to 750 HV were investigated in
single-grit abrasion. In the cyclic abrasion experiments,
the abrasion resistance of the steels was improved
noticeably from the initial state due to surface
hardening. However, the highest surface hardening rate
did not result in the highest wear resistance. Moreover,
when the surface loading was sufficiently increased, the
transition to a high wear rate mechanism was observed.
