This paper discusses a fractal approach to understand nature inspired laser surface engineered coatings. Via a laser surface engineering process a multi‐scale CaTiO 3 coating was synthesized on Ti alloy surface. At faster laser processing speeds star like CaTiO 3 features evolved inside rings rich in calcium phosphate and TiO 2 . The porosity developed through the distribution of these particles results in a multi‐scale distribution. Fractal analysis revealed that such laser processed surfaces had consistent fractal dimension over multiple length scales. This multi‐scale and multi‐phase surface microstructure contributed to enhanced biomimetic precipitation.
