I would like to measure the hardness of hard anodized aluminum with a Silvex, is that possible?
Q: I would like to measure the hardness of hard anodized aluminum. What thickness in μm would be appropriate to achieve suitable hardness, and is it possible to measure it? A: The hardness of anodized aluminum does not change whether it is 5μm or 50μm. However, when measuring Vickers hardness (Hv), a thickness of at least 20μm is required for micro Vickers. This is because the hardness of the anodized coating is measured in relation to the cross-section of the anodized layer. Vickers hardness is determined by measuring the size of the indentation left by a diamond. If the anodized layer is less than 20μm thick, it is not possible to measure the size of the indentation on that cross-section.
