Abstract

In this aluminum metal powder, specimen reinforced with o, 4, 8, and 12 Wt. % of WC were prepared by powder metallurgy route. Universal Testing Machine (UTM) was used to prepare these Al-WC specimens at compaction pressure 80KN. A muffle furnace was used to sinter these specimen at 620°C.An abrasive wear test was done on a pin-on-disc wear tester using silicon abrasive media of sintered specimens. These sintered specimens were characterized using scanning electron microscopy (SEM) along with dispersive energy spectrum (EDS), X-ray diffraction (XRD), and hardness. The result shows that hardness and wear resistance increase up to 8 wt. % of the optimum amount of WC and Al-8WC sintered specimen exhibits minimum wear loss and higher hardness due to refined microstructure and strong bonding between Al and WC. Cutting, ploughing, and fracture wear mechanisms were identified in the sintered specimen. Keyword: Al; WC; abrasive Wear; SEM; XRD; hardness.
