Abstract [en]
Composite materials exhibiting excellent mechanical properties such as high ductility and extreme strength to be used in a wide range of applications. Tungsten carbide (WC) particles were used to reinforce Hadfield steel to enhance its hardness and its wear resistance. This work consists of the fabrication of metal matrix composite (MMC) based WC. It was found that WC carbide particles were successfully obtained in all the prepared samples. Each sample presents different mechanical properties depending on the microstructure obtained. Scanning Electron Microscopy (SEM) Elemental Dispersive Spectroscopy (EDS) and optical microscope were used to analyse the microstructure. Finally, the hardness was tested on all composite samples, and it has been found that it has improved from 280 HV to 640 HV.
