A hydroxyapatite coating layer with excellent bio-compatibility and a preparation method thereof are provided to be used broadly in a medical implant or an artificial coxa and to have a dense structure without cracks. A preparation method of hydroxyapatite coatings with excellent bio-compatibility includes: performing first heat treatment of hydroxyapatite powder consisting of micro particles at 1,000-1,300 deg.C; forming the mean diameter of powder particles to be 0.1-5 micrometers by giving mechanical shock to powder obtained in first step; performing a second heat treatment of powder obtained in second step at 200-1,100 deg.C; and coating the hydroxyapatite powder obtained in third step on the surface of a ceramics material including a metal material, alumina, or zirconia.
