Dry sliding wear behaviour of A356–TiB 2 composites in T6 condition was tested using a pin-on-disc wear testing machine. The composites were prepared by the reaction of a mixture of K 2 TiF 6 and KBF 4 salts with molten alloy. The wear tests were conducted at normal loads of 19.6–78.4N and a sliding speed of 1ms −1 . A detailed SEM study of wear surface and...
Al–7Si alloy reinforced with in situ TiB 2 particles was synthesized successfully by using salt reaction route. These in situ composites have shown significant improvement in mechanical properties in comparison to the base alloy. The wear resistance of the alloy also significantly improved with the addition of TiB 2 particles. The hardness, strength and wear resistance increased with...
Dry sliding wear of as cast and different annealed states of Cu 60 Zr 30 Ti 10 bulk metallic glass was studied using pin-on-disc measurement technique. The relaxed metallic glass showed high hardness and excellent wear resistance. An inverse relation between the hardness and wear rate was observed for the as cast and annealed metallic glass. Coefficient of friction measured...
