Abstract
A cylinder block is provided with a cylinder bore and a thermally sprayed metallic coating disposed on an internal wall of the cylinder bore. The internal wall has first and second wall sections that are located at different axial locations along the internal wall of the cylinder bore. The thermally sprayed metallic coating is disposed on the internal wall of the cylinder bore by spraying droplets of a molten metal. The thermally sprayed metallic coating includes a first thermally sprayed coating portion having a first iron oxide concentration and a second thermally sprayed coating portion having a second iron oxide concentration. The first thermally sprayed coating portion is disposed on the first wall section. The second thermally sprayed coating portion is disposed on the second wall section. The second iron oxide concentration is different from the first iron oxide concentration.
