| Abstract Scope |
Aluminium-silicon alloy reinforced with titanium diboride particulates can be considered to be an advanced material that is capable of selection and use in both performance-critical and non-performance critical applications. The exothermic reaction that occurs between the hexafluoro titanate (K2TiF6) and potassium borofluoride (KBF4) salts and the molten aluminium-silicon alloy results in the precipitation of fine TiB2 particulates as the reinforcing phase for the metal matrix. Test specimens were prepared by varying the volume fraction of the reinforcing TiB2 particulates in the chosen aluminium alloy metal matrix. Energy-dispersive X-ray spectroscopy was conducted to confirm the presence of titanium and boron in the microstructure. Microstructural investigations of the as-processed composite specimens revealed a near uniform distribution of the reinforcing through the chosen metal matrix. The dry sliding wear behaviour of the engineered composites were studied using a pin-on-disc tribometer. Both weight loss and wear rate were precision determined for various conditions |
