About the Elaboration and Characterization of Fe-Based Composite with Friction Destination
The present research’ goal is the fabrication of Fe-based composite reinforced with oxide particles with special characteristics (wear, friction coefficient) for friction applications usually the Fe-based composite are obtained through melting and castings followed by other finishing operations. These technologies do not ensure a homogeneous distribution of reinforcement particles and that is why, the authors approached a PM specific technologies to obtained Fe-based composite. The Fe-based powder reinforcement with oxide particles obtained through mechanical alloying the powder was analyzed and characterized and then underwent the operation of milling in the planetary milling with ball, pressing and sintering at different temperatures and durations. SEM analysis had of identifying the distribution compounds into the Fe- matrix, their quantitative evolution and the influence of different parameters. The mechanical characteristics, wear and friction coefficient, were determined.
