Abstract

In this paper, an attempt has been made to characterize the dewaxed tungsten carbide-based self-lubricant cutting tool material. In the course of characterization, crystalline size, particle size and morphological analysis were carried out using X-ray diffraction (XRD), transmission electron microscope (TEM) and scanning electron microscope (SEM), respectively. The XRD result confirms that the intensity of the diffraction peaks broadened for 40 h of milling as compared to raw powder sample. The result reveals the fracture resistance of beyond 40-h-milled particles increased, as strong cohesion between small particles occurs. The SEM analysis reveals the homogenously rounded grains of tungsten Carbide-Cobalt-5 wt% Calcium Fluoride system with 4 wt% stearic acid after 40 h of milling. The TEM analysis showed the homogeneous distribution of tungsten carbide particles in the considered milled samples in 40 h with the minimum possibility of agglomeration as compared to 100-h-milled powders.
