SEM images of the cross sections of (a1) nHA_100, (a2) nHA_400, (b1) mHA_100, and (b2) mHA_400 coatings on Mg substrates after TPA deposition. The coating thickness was 82.8 ± 7.3 μm for nHA_100, 143.8 ± 25.2 μm for nHA_400, 119.0 ± 10.9 μm for mHA_100, and 116.4 ± 6.6 μm for mHA_400. The original magnifications were 500x for all images.
