PURPOSE: A method for manufacturing a biocompatible implant is provided to improve the adhesive force of a hydroxyapatite coating layer. CONSTITUTION: A method for manufacturing a biocompatible implant comprises: a step of providing an implant type base metal which is made of titanium or low elastic alloy and has a surface average illuminance of 0.8-8.0 micrometers (S10)； a step of forming a hydroxyapatite coating layer on the surface of the implant type base metal through a low temperature high speed collision method of 100°；C or less (S20)； and a step of washing the implant type base metal formed with the hydroxyapatite coating layer by immersing the base metal in liquid (S30). The coefficient of the low elastic titanium alloy is 80 GPa or less. [Reference numerals] (S10) Step of providing an implant type base metal which is made of titanium or low elastic alloy and has a surface average illuminance of 0.8-8.0 micrometers； (S20) Step of forming a hydroxyapatite coating layer on the surface of the implant type base metal through a low temperature high speed collision method of 100°；C or less； (S30) Step of washing the implant type base metal formed with the hydroxyapatite coating layer by immersing the base metal in liquid생체친화성 임플란트의 제조방법이 개시된다. 본 발명에 의한 생체친화성 임플란트의 제조방법은 티타늄 또는 저탄성 티타늄 합금으로 제조되며, 표면부 평균조도가 0.8~8.0㎛로 조절된 임플란트형 기지금속을 제공하는 단계, 상기 임플란트형 기지금속의 표면에 100℃ 이하의 저온 고속충돌법에 의해 수산화 아파타이트(hydroxyapatite； HA)의 코팅층을 형성하는 단계, 및 상기 수산화 아파타이트의 코팅층이 형성된 임플란트형 기지금속을 액체에 침적하여 수세하는 단계를 포함한다.
