Özet

In this work, the hardness and abrasive-wear be-haviour of powder metallurgy (PM) plain carbon steel and microalloyed steels with different amount of niobium or aluminium content (0.1-02 wt.-%) were investigated. It was found that steels microalloyed by niobium and alumin-ium have high hardness and wear resistance compared with the niobium and aluminium free steel. Wear behavior of these steels depends on the PM processing parameters and wear conditions. Worn surface pattern revealed the wear mechanism is ploughing. The surface exhibited extensive grooving occured as a result of ploughing by the harder SiC paper.
