The longitudinal section of the pin at the region of the thermal spray layer detachment, showing that the pin suffered a localized lateral bending with strong plastic deformation, responsible for the layer detachment. The figure shows the external surface (top of the figure) with the layer detachment (gray aspect), the thickness of the pin (deformed) and the internal surface (bright aspect).
