Grinding - Machine Tools & Metrology

7/7/2018· Silicon carbide Silicon carbide is harder than alumina but less tough. Silicon carbide is also inferior to Al2O3 because of its chemical reactivity with iron and steel. Black carbide containing at least 95% SiC is less hard but tougher than green SiC and is efficient for grinding soft nonferrous materials. Green silicon carbide contains at least 97% SiC.

Investigation of two-body abrasive wear (Conference) | …

27/7/2020· The work focused on the influence of the type of abrasive particles (alumina and silicon carbide) on the wear rate and the dominating wear mechanisms. A solid-state-sintered silicon carbide (SiC), a silicon carbide reinforced with titanium diboride particles (SiC-TiB{sub 2}) and two hot-pressed silicon carbide-whisker-reinforced alumina materials (WRA I and WRAII) were studied.
