Fig. 18 Fine flaking damage on the surface of a shaft that served as a roller-bearing inner raceway. The flaking originated along the ridges of the surface finish of the shaft. More

Fig. 27 Similar to flaking, although peeling tends to be associated with soft and pliable fresh coatings that can be pulled away from or spontaneously flake away from the substrate or from between coats, due to loss of adhesion More

Fig. 2 Schematic of the powdering and flaking of galvannealed coatings on sheet steels. OD, outside diameter; ID, inside diameter More

Fig. 37 Flaking of oxide scale during water quenching of S45C carbon steel. Water temperature is 30 °C (85 °F). Test specimen is a solid cylinder 10 mm (0.4 in.) in diameter by 30 mm (1.2 in.) in length. (a) Light oxide coating after heating for 3 min at 860 °C (1580 °F) in air in argon gas More

Fig. 28 Comparison of number of repeated impacts that lead to flaking of coatings in repeated hammering with a cemented carbide ball of 6.35 mm (0.25 in.) diameter. TRD, thermoreactive deposition/diffusion; PCVD, plasma chemical vapor deposition; PVD, physical vapor deposition More

Fig. 29 Comparison of numbers of cycles at which flaking of coatings occurred in a rolling test with 10% sliding. CVD, chemical vapor deposition; TRD, thermoreactive deposition/diffusion; PVD, physical vapor deposition More

Fig. 50 (a) Fine flaking damage on the surface of a shaft that served as a roller-bearing inner raceway. The flaking originated along the ridges of the surface finish of the shaft. (b) Flaking (also known as micropitting) due to poor lubrication within a cylindrical roller bearing More
