Abstract
Tungsten carbide is known to have excellent corrosion resistance and high hardness within carbide ceramics. Due to their superior mechanical properties and wear resistance, tungsten carbide cutting tools containing Co binder have been the subject of many studies. There are a limited number of works regarding the use of Ni and Fe as a binder in tungsten carbide based composites, especially processing with microwave radiation. In this study, a composite cutting tool made of electroless nickel coated tungsten carbide ceramic powder was produced by microwave sintering. Two different tungsten carbide powder sizes of 2 µm and 10 µm were used for the production of composite cutting tool. The microwave sintering was carried out at two different temperatures of 1200 and 1400 ° C for 2 hours. Characterization of composite cutting tools was made by XRD, hardness, compression test and electron microscopy techniques.
