Abstract

The present paper investigates the effect of sintering temperature and graphite content on the microstructure and effect on wear and frictional properties of Fe C powder metallurgy preforms For the present work the specimens were prepared with graphite content 0 5 1 1 5 and 2 by weight and were sintered at three sintering temperature 800 C 900 C and 1050 C Microstructural properties were evaluated using scanning electron microscopy The wear and friction property of the powder preforms were tested on Pin-On-Disc apparatus The powder specimen was used as pins and the disc was of AISI 51200 steel The experiments was carried out under load of 40 N speed 1000 rpm time 1500 seconds and relative humidity 60 - 65 The result was 2 graphite content specimen with sintering temperature 1050 C showed good wear resistance The wear rate decreased with the increase in sintering temperature and increase in graphite content of the specimen
