Description	The influence of layering sequence of plasma sprayed composite coatings on the fatigue life was studied. Plain, grit-blasted, and plasma sprayed specimens with one to three coating layers were examined. The layered coatings were composed of alternating sequence of ceramic (Cr2O3) and metallic (Ni10wt%Al) deposits. Deflection controlled resonance symmetrical bending fatigue tests of flat specimens were performed. The deformation amplitude was 1.3 millistrain in the crack initiation site and loading frequency was around 80 Hz. The significance of the effect of surface treatment on fatigue properties was examined statistically using Wilcoxon test.From the obtained data,the effect of individual layers was deduced.In order to explain the observed fatigue behavior, the fractographic analysis was performed and the coating–substrate composite was characterized.Strain hardening profile in the substrate was estimated by microhardness measurement and electron back scatter diffraction The influence of layering sequence of plasma sprayed composite coatings on the fatigue life was studied.
