Tribological Properties of Silicon Carbide and Silicon …

A monolithic SiC ceramic and two SiC–C composite ceramics containing 10 and 20 vol% graphite were fully densified with Al 4 C 3 and B 4 C as additives. The tribological properties of these materials were evaluated by sliding against sintered silicon carbide under

Tungsten vs Tungsten Carbide - differences in …

Tungsten already has a large elastic modulus, one larger than most steels; tungsten carbide has an even great elastic modulus, showing its impressive rigidity. Generally, materials stiffness correlates with a large elastic modulus, and the values shown in Table 1
