Corrections The published article contains an error in the sketches of the projected hexagonal cells that have been used to indicate two particular substrate grain orientations and to label associated data. In the published article, the projected hexagonal cells indicating the substrate grain orientations ∼Ti{101̅0} (blue, label D, 50° ≤ Φ ≤ 90° and 0° ≤ φ2 ≤ 15°) and ∼Ti{21̅1̅0} (green, label E, 50° ≤ Φ ≤ 90° and 15° ≤ φ2 ≤ 30°) are interchanged in Table 1 and Figures 2−4. The labels used in Figure 1 are correct. The error does not affect the scientific interpretation of the work. The changes listed in the following table have been done to correct the error in the published article. The Supporting Information has been corrected accordingly. table/figure performed change Table 1 interchange of the projected hexagonal cells assigned to the substrate grain orientations ∼Ti{101̅0} and ∼Ti{21̅1̅0} Figure 2 interchange of the projected hexagonal cells assigned to 1. the substrate grains with labels D and E in the table 2. the substrate grain orientations (101̅0) and (21̅1̅0) in the standard triangle (and adjustment of the respective color) Figure 3 interchange of the projected hexagonal cells assigned to the green and blue spectra Figure 4 replacement of the projected hexagonal cell depicted in Figure 4a,b by the correct sketch Below, the corrected table and figures are listed.

Figure 2. Chemical maps from Ti 2p3/2 (always left) and C 1s (always center) photoelectron micrographs of TiOC, and EBSD maps (always right) of the corresponding Ti substrates. (a) TiOC550, (b) TiOC650, (c) TiOC750, and (d) TiOC850. To facilitate discrimination between the different TiOCs, the chemical maps are differently colored. Table: approximate orientation of the labeled grains. Standard triangle: color-orientation code of the EBSD maps.
Figure 3. Spectra from Ti 2p3/2 (top) and C 1s (bottom) core-level maps of TiOC, acquired on top of substrate grains with five different orientations, as indicated by the hexagonal cells using the color-orientation code. (a, e) TiOC550, (b, f) TiOC650, (c, g) TiOC750, and (d, h) TiOC850. The spectra in (b, c) are scaled to the TiO2 component height. 3077

Purple spectrum in (a): as-grown anodic TiO2. (b, d) Spectral range marked by the box in (a, c). Baseline correction: (a, c) subtraction of fourth-order polynomial function; constant shift to a common level at (b) 800 cm−1 and (d) 150 cm−1. (e) Photographs of TiOC specimen.
