The tribologicai behavior of some steel samples prepared by powder metallurgy sintered in microwave field

摘要

The objective of this research is to study the influence of the sample composition on the wear testing for some steel samples elaborated by powder metallurgy technology. For obtaining the steels there were used iron powders and graphite powders. The powders were homogenized in a high energy ball mill Pulverisette 6, cold compacted and then sintered using a Muegge type microwave heating installation. The influence of the samples' composition on the wear parameters is studied using both a tribometer and a profilometer.
