Characterization of hydroxyapatite coating by pulse laser deposition technique on stainless steel 316 L by varying laser energy

▸ Hydroxyapatite coating was successfully deposited on stainless steel substrate by pulse laser deposition at different energy levels (i.e. 300 mJ and 500 mJ, respectively). ▸ Variation in laser energy affects the surface characteristic of hydroxyapatite coating (particle size, surface roughness, uniformity, Ca/P ratio). ▸ Laser energy between 300 mJ and 500 mJ is the optimal choice for obtaining ideal Ca/P ratio.
