Tungsten carbide is known for its advantageous properties, such as its high melting point, high hardness, low friction coefficient, and chemical stability [ [1], [2], [3], [4] ]. Owing to these excellent mechanical properties, tungsten carbide thin films are used as wear-resistant coatings for mechanical parts, molds, and drilling tools [ 4, 5 ].

Tungsten is a dull silver-colored metal with the highest melting point of any pure metal. Also known as Wolfram, from which the element takes its symbol, W, tungsten is more resistant to fracturing than diamond and is much harder than steel. This refractory metal's unique properties—its strength and ability to withstand high temperatures ...

Electrically Conductive Tungsten Copper Rods. Use these rods for electrodes in the electrical-discharge machining of dense material, such as tungsten carbide— they're 75% tungsten for wear and arc-erosion resistance and 25% copper for electrical and thermal conductivity. They're also known as Elkonite rods.

Gamma-rays from 123 I, 133 Ba, 152 Eu, and 137 Cs were irradiated on tungsten carbide and lead samples with various thickness to evaluate the attenuation coefficient properties at energies ranging from 0.160 MeV to 0.779 MeV. Three measurement were performed for each sample thickness at each gamma energy.

Testing tungsten carbide cermets at high strain rates is difficult due to their high stiffness and brittle failure mode. Therefore, the aim of this study is to apply the image-based inertial impact (IBII) test methodology to analyse the high strain rate properties of tungsten carbide cermets. The IBII test uses an edge on impact test configuration with …
