N2 - Hydroxyapatite (HA) has been universally used because of good biocompatibility. There are varieties of coating methods, however, they still have problems. The most significant problem is layer thickness. We introduced a new coating procedure to eliminate this difficulty. The characterization of the coating was studied by X-ray diffractometry, infrared spectroscopy, SEM and chemical analysis. Said examination indicated that the double layer consisted of carbonate HA and CaTiO3 and the thickness of the layer was 2-4 μm. The coating was performed on the inner surfaces of 50-200 μm sized pores and was also consistent in the smallest of the pores even those of 50 μm. Our results indicated that the coating layer was homogeneous and thin. In addition, both layers consisted of Ca ions. The consistency of coating into even the smallest pore size suggested that our method promises to have widespread clinical applications in artificial implants because of increased surface contact area.
