A coated part is exposed to a gas flow. The gas flow has a characteristic gas flow direction distribution over a surface of the coated part. The coated part has a substrate having a substrate surface and a coating over the substrate surface. The coating comprises at least one coating layer. A first such layer is columnar and has a column boundary direction distribution. The column boundary direction distribution is selected for partial local alignment with the gas flow direction distribution.
