Surface Preparation Laboratory prepares and polishes the surfaces of polycrystals to fully expose the interior structure of a piece of material. We remove the damage that is caused by mechanical cutting, grinding or sanding and suitably prepare your sample using diamond polishing, colloidal silica or chemical-mechanical polishing techniques. This service can be performed for customers seeking to prepare samples for e.g. X-ray diffraction or EBSD analysis. We can provide polycrystalline elemental or alloy material, or you can provide the material yourself.
