Synthesis and air jet erosion wear behavior of aluminum – Al3Ti In-Situ composite

A deformation-processed Cu-10Fe-3Ag in situ composite was made by consumable arc melting and casting followed by extensive deformation. A superior combination of mechanical strength and electrical/thermal conductivity was achieved with the composite since Fe filaments existed in the copper matrix. The effects of sliding speed and electrical current on sliding wear behavior and microstructure of the composite were investigated on wear tester. Worn surfaces of the Cu-10Fe-3Ag in situ composite were analyzed by scanning electron microscopy (SEM). Within the studied range of electrical current and sliding speed, the wear rate increased with the increasing electrical current and the sliding speed. Compared with Cu-10Fe in situ composite under the same conditions, the Cu-10Fe-3Ag in situ composite had much better wear resistance. Adhesive wear, abrasive wear and arc erosion were the dominant mechanisms during the electrical sliding processes.

Friction And Wear Tests

Al6061-TiC in-situ composite was developed using hexafluorotitanate salt and graphite powder. Microstructure studies, hardness and dry sliding friction and wear behavior were investigated for both base alloy and in-situ composite. Friction and wear tests were performed at the normal load and sliding speeds in the range 20-100N and 0.314-1.57m/s respectively. For a given TiC content, coefficient of friction was lower than base alloy for all the loads and sliding speeds. A tremendous improvement in the wear resistance of the composite was found when compared with base alloy.
