“…In the later case, it means that higher value of plastic strain would no more change the residual stress in martensite. It should be emphasized that these explanations are also consistent with the anisotropy of the Barkhausen noise response (0 • and 90 • ) and with results reported by several authors (see for example [21]). Indeed, the increase of the height of the Barkhausen peak is greater for the measurements performed with a magnetic field parallel to the tensile axis, for which the residual stress in the martensite phase is greater, than for the measurements performed with a magnetic field perpendicular to the tensile axis, whose direction (transversal) corresponds to a less significant increase of the residual stress induced by the tensile deformation.…”

“…Anodic coatings generally decrease the fatigue strength of a material. The influence of anodization on the fatigue life of WE43A‐T6 magnesium was investigated and a decrease in the fatigue strength was observed 15 . Furthermore, anodic coating influenced both crack initiation and propagation processes.…”

A B S T R A C T In recent years, with higher demand for improved quality and corrosion resistance, recovered substrates have been extensively used. Consequently residual stresses originated from these coatings reduce the fatigue strength of a component. Due to this negative influence occasioned by corrosion resistance protective coatings, an effective process like shot peening must be considered to improve the fatigue strength. The shot peening treatment pushes the crack sources beneath the surface in most of medium and high cycle cases due to the compressive residual stress field (CRSF) induced. The aim of this study was to evaluate the influence on the fatigue life of anodic films grown on 7050-T7451 aluminium alloy by sulphuric acid anodizing, chromic acid anodizing and hard anodizing. The influence on the rotating and reverse bending fatigue strength of anodic films grown on the aluminium alloy is to degrade the stress life fatigue performance of the base material.A consistent gain in fatigue life in relation to the base material was obtained through the shot peening process in coated specimens, associated to a residual stress field compressive near the surface, useful to avoid fatigue crack nucleation and delay or even stop crack propagation.
