“…Guo et al [46] compared the fatigue lives of hardened bearing-steel (62 HRC) specimens subjected to turning with PCBN and grinding with alumina wheels. Surface compressive stresses were induced in both sets of specimens, which were free of white layer.…”

Surface integrity comprises the study of the alterations induced during the manufacture of a component that might affect its properties and service performance. Therefore, additionally to geometric irregularities (surface texture and both dimensional and geometric deviations), the study on surface alterations (such as metallurgical alterations, cracks and residual stresses) induced by hard-part machining is of utmost importance, especially in the case of components subjected to dynamic loading. Consequently, this chapter is focused on the investigation of the influence of tool material and geometry and cutting parameters on the surface integrity of components subjected to hard-part machining and, when applicable, comparisons are drawn with grinding and non-conventional processes, especially electrical discharge machining (EDM). Geometric IrregularitiesOwing to the fact that in most cases hard-part machining is employed as an alternative to grinding, the requirements concerned with surface texture (microgeomet-__________________________________ A.M.

“…Therefore, white layer has significant effects on the performances of machined components. On one hand, it could be beneficial to the abrasion resistance of components because of its high hardness [5,6]; on the other hand, it would be harmful to the fatigue resistance of components due to the presence of micro-crack and tensile residual stresses existing in the white layer [7,8]. In machining of steels, thermal and mechanical effects were considered to be the two major driving factors of white layer formation [9][10][11][12][13][14].…”

“…In machining of steels, thermal and mechanical effects were considered to be the two major driving factors of white layer formation [9][10][11][12][13][14]. The thickness of white layer ranges from a few microns to a few tens of microns, and the formation of white layer is known to be related to cutting conditions [2,7,15]. White layer is more likely to appear when the cutting tool is seriously worn or aggressive cutting parameters are used, and tool flank wear is a dominant factor that influences white layer thickness [16][17][18][19].…”

In the field of hard cutting, researches on white layer have become more extensive and in-depth in recent years, because white layer has an important influence on the performances and life of components. Nevertheless, properties of white layer, especially its corrosion properties, have not been well understood or clearly defined. In this study, specimens with different subsurface microstructures (no obvious change, dark layer, and white layer) were produced in the process of tool wear to analyze their electrochemical properties using electrochemical methods. It was found that electrochemical properties were distinct between specimens with and without white layer. A specimen with white layer had obviously lower electrochemical impedance and more anodic steady-state open-circuit potential than that without white layer in 3.5 wt.% NaCl solution. That is to say, specimens with white layer were prone to corrosion in this solution. The results also manifest that electrochemical method can be a reliable, convenient, and nearly nondestructive method to detect white layer.

“…It has been known for some time that hard turning can lead to the formation of austenite on the surface, which then transforms into fine martensite. 13,14 In their paper on machining-induced white matter, Umbrello et al 15 show that if the machining is carried out at cryogenic temperatures, then the nature of the white matter on the surface changes because austenitisation does not occur. They use standard constitutive models based on the ZenerHolloman equation 16,17 to implement a finite element calculation of the thickness of the machining-induced white matter.…”
