Beschreibung
Zusammenfassung:	A composite hydroxylapatite coating layer and preparing method thereof belongs to the related field of the biological medical material artificial implant. The composite hydroxylapatite coating layer disclosed by the invention comprises a bottom layer contacted with a substrate and a surface layer covered on the bottom layer. The preparation steps of the composite coating layer comprising: respectively spray coating hydroxylapatite powders to the bottom layer on the substrate and to the surface layer on the bottom layer adopting microbeam plasma spray coating apparatuses, the method preparation process is simple the powder using rate is high, the prepared composite coating layer has characteristics of good biological activity and good biological stability, the coating layer and the substrate have higher bond strength.
