Abstract: Provided is a method of forming an apatite coating, including brining an apatite-forming precursor solution including Ca2+ ions and PO43− ions into direct contact with at least one region of the substrate, emitting a laser beam onto the region of the substrate in direct contact with the precursor solution through the precursor solution, and forming apatite on the region onto which the laser beam is emitted.

Abstract: Provided is a method of synthesizing apatite powder by emitting a laser beam to a surface of a substrate immersed in a precursor solution. The method is including immersing a substrate in an apatite-forming precursor solution, emitting a laser beam to a region on a surface of the substrate immersed in the precursor solution, and obtaining apatite powder generated in the precursor solution.

Abstract: Provided is a method of forming an apatite coating, the method including immersing a substrate in an apatite-forming precursor solution including Ca2+ ions and PO43− ions, emitting a laser beam onto a surface of the substrate immersed in the precursor solution, and forming an apatite coating in a region exposed to the laser beam, wherein an output power of the laser beam is set within a range enabling the surface of the substrate to be melted.
