Can you identify the type of wear?

Can you identify the type of wear? Analytical Ferrography allows analysts to visually examine wear particles present in a sample. A trained analyst visually determines the type and severity of wear deposited onto the substrate by using a high magnification microscope.  The particles are readily identified and classified according to size, shape, and metallurgy. The image…
