Abstract
Dry sliding wear behaviour is fundamental
mainly in typical components in manufacturing which has been
found to correlate to both safety and cost effective. Thus, wear
behaviours were carried out using ball-on-disc tribometer
equipment called CETRUMT-2 which operates with linear
reciprocating motion drive. Ball-on-disc test is regarded as one
of the most common tests used to study and analyse the wear
behaviour. Evaluating the wear volume and wear rate of
respective samples, ball-on-disc tests were performed on the
Universal Micro materials Tester (UMT-2), produced by
Centre for Tribology, Inc. (CETR), USA. The wear tests were
performed using a tungsten carbide ball of about 10 mm
diameter with a constant stroke length of 2 mm together with
application normal load of 25 N. Thus, frequency for the
reciprocating spindle was maintained at 5 Hz together with
speed of 5 mm/s which was also maintained throughout the
test. In this paper, the ball-on-disc was used for the
investigation of the effects of normal load and hardness of
Ti6Al4V-B4C composites on wear behaviour under dry and
sliding conditions...
