A new method (sintering method)to prepare hydroxylapatite coating of implants was developed. The coating was characterized by X-ray diffraction(XRD) and infrared spectroscopy with a Nicolet FTIR aparatus. The adhesion strength of coating to metal substrate were measured. The bone ingrowth of coated substrate was observed and clinical application of coated implants were reported in this paper. The comparison results of sintered coating and plasma sparied coating was discussed.
