Fig. 10 Scanning electron microscope image of a microscopic region of adhesive wear on a hardened-alloy-steel piston component from a hydrostatic pump (500×). Material has been transferred by microwelding from the adjacent component wall surface during sliding and poor lubrication conditions. More

Fig. 6 Typical scanning electron microscope used for microscopic analysis of a fracture surface More

Fig. 14 Intergranular fracture viewed under the scanning electron microscope. Note that fracture takes place between the grains; thus, the fracture surface has a “rock candy” appearance that reveals the shapes of part of the individual grains. More

Fig. 2 Scanning electron microscope image of an area of abrasive wear on a soft, low-carbon-steel shaft bearing component, showing classic features of material “cutting” action (100×). More

Fig. 13 Typical scanning electron microscope fractograph showing fatigue-crack propagation. Each striation, or ridge, on the fracture surface corresponds to one fatigue load cycle. The arrow indicates the crack propagation direction. More
