Abstract

The influence of holding time on the dry sliding wear characteristics of spark plasma sintered Ti6Al4V powders was investigated. Pre-alloyed powders were sintered at constant temperature, heating rate and pressure of 850 °C, 100°C/min and 50 MPa respectively with holding time varied between 2 - 10 min. Wear tests were performed at two loading levels of 15 and 35 N using the ball-on-disc tribometer configuration with WC as the counterface material. Characterization of wear tracks and debris were carried out with SEM and EDX techniques. The friction coefficient and wear depth increased with sliding time. Wear rates also increased with applied load. Worn surface analysis showed both features of abrasive and adhesive wears with the latter dominant at higher applied load of 35 N. Optimum wear performance was achieved with sample sintered at 6 min holding time.
