Experiment 3 Metallographic Observations

Grinding must be carried out carefully in such a way that all microscopic constituents in the surface are preserved and that the grinding medium is not embedded in the sample To achieve this, the specimen is ground on successively finer grades of emery sand paper During grinding, the specimen is held with...

Metallographic grinding and polishing insight Struers

Fine grinding produces a surface with little deformation that can easily be removed during polishing Because of the drawbacks with grinding papers, alternative fine grinding composite surfaces are available, in order to improve and facilitate fine grinding, A high material removal rate is obtained by using grain sizes of 15, 90 and 60 181 m...
