Investigation of Dry Sliding Wear Behavior of Powder Metal (P/M) Materials Produced from Mixture of Fe-Cu-C Powders

Abstract

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.
