Abstract

Hardness is one of the mechanical properties of a material. The hardness of the material must be known, especially those that will be used to face (Fritctional force) and a small work of mechanical materials obtained from plastic deformity (deformity given and subsequently submitted), not returning to its original shape due to space by an article as test equipment. This test uses a tool called a Shore Hardness tester.Scanning electron microscope (SEM) is a kind of electron magnifying device that uses electron pillars to describe the surface state of the dissected sample. SEM has a higher purpose than optical magnifying instruments (OM). This is because the de 31 Broglie frequency has more limited electrons than the OM wave. Because the lower the frequency used, the higher the objective of the magnifying lens. SEM has a higher purpose than OM. The goal that can be delivered by OM is only 200 nm, while the goal that can be made by SEM is 0.1 – 0.2 nm.
