Abstract

 

In this study, dry sliding wear behavior of powder metal parts produced
from ASC.100.29 iron powder has 0.28-40 μm particle size range and containing 2
% Cu and 0.75 % C were investigated using pin-on-disk method. In order to obtain cylindrical samples within
10 mm diameter and 20 mm length iron powder were compacted at 800 MPa pressure
in a single action press. Then compacted powder metal parts were sintered at
1100 °C temperature for two hours in an atmosphere controlled tube furnace.
After the sintering process, micro structural analysis, hardness and density
measurements of powder metal parts were performed.  After, the characterization of samples dry
sliding wear tests were performed according to ASTM-G55-05 by using TRIBOMETER
T10/20 pin-on-disk wear device. Wear tests were
carried out at different loads (10-15-20 N), with the other test parameters being
constant, to investigate the wear behavior of powder metal parts in relation to
load. The test results showed that the increasing of
load resulted in increase of wear values.
