How is the Vickers Hardness Test Conducted on Catalytic Materials?
To perform the Vickers Hardness Test on a catalytic material, a small, polished sample of the material is prepared. The diamond indenter is then pressed into the sample under a specific load, which can vary depending on the material being tested. After the load is removed, the diagonals of the resulting indentation are measured using a microscope. The Vickers hardness number (VHN) is calculated using the formula: VHN = 1.854 * (Load / Diagonal²)
