Effect of Boron Carbide Addition on Wear Resistance of Aluminum Matrix Composites Fabricated by Stir Casting and Hot Rolling Processes

Effect of Boron Carbide Addition on Wear Resistance of Aluminum Matrix Composites Fabricated by Stir Casting and Hot Rolling Processes

In this study, to evaluate the effect of boron carbide (B<sub>4</sub>C) addition on the wear performance of aluminum (Al), Al6061 and 5, 10, and 20 vol.% B<sub>4</sub>C/Al6061 composites were manufactured using the stir casting and hot rolling processes. B<sub>4</sub...

B<sub>4</sub>C particles were randomly dispersed during the stir casting process; then, B<sub>4</sub>C particles were arranged in the rolling direction using a hot rolling process to further improve the B<sub>4</sub>C dispersion and wear resistance of the composites. Furthermore, a continuous interfacial layer between B<sub>4</sub>C and the Al6061 matrix was generated by diffusion of titanium (Ti) and chromium (Cr) atoms contained in the Al6061 alloy. Wear depth and width of the composites decreased with increasing B<sub>4</sub>C content. Furthermore, with B<sub>4</sub>C addition, coefficient of friction (COF) improved as compared with that of Al6061. The results indicate that interface-controlled, well-aligned B<sub>4</sub>C particles in the friction direction can effectively increase the wear properties of Al alloys and improve their hardness.https://www.mdpi.com/2075-4701/11/6/989aluminum matrix compositeboron carbidehot rollingstir castingwear property
