The present invention relates to a method for coating a surface of a titanium implant, which is widely used as a grafting material, with low crystalline hydroxyapatite, and an implant coated with low crystalline hydroxyapatite having network- or island-like morphology, by the same method. The method includes 1) pretreating a surface of a titanium or titanium alloy implant, 2) adding each of a phosphate ion solution and a calcium ion solution to the pretreated titanium or titanium alloy implant, and 3) dipping and storing the titanium or titanium alloy implant in the calcium phosphate solution for 1 hour or more.
