本文采用真空等离子喷涂设备（VacuumPlasmaSprnySystem），在不偷呐涂功率下制备了羟基磷灰石涂层，研究了热喷涂功率对羟基磷灰石涂层材料学特征的影响．实验中，使用X射线衍射仪，测定了涂层的相组成．使用扫描电子电镜，观察了羟基磷灰石涂层的表面形貌．研究结果表明，热喷涂功率对羟基磷灰石涂层的结构有着重大的影响．一方面，随着热喷涂功率的提高，涂层的非晶化加剧，涂层中非晶态的羟基磷灰石含量不断增大．另一方面，随着热喷涂功率的提高，羟基磷灰石粉末的熔化状态变好，颗粒之间的结合能力加强；涂层的显微结构明显改善．

Hydroxyapatite coatings were made under different spray power using a Vacuum Plasma Spray System. The effects of spray power on characteristics
of hydroxyapatite coatings were investigated. In the experiment, X Ray Diffractometer and Scanning Electron Microscopy were used to detect phase compositions and
microstructures of as-received coatings. The results obtained indicated that, plasma spray power greatly effectsed the characteristics of the as-received
coatings. With the increase of spray power, hydroxyapatite content of as-received coatings decreased, showing the amorphorization of coatings was prompted. Also,
with the increase of spray power, the melt of hydroxyapatite was improved, the coatings with good microstructures were obtained.
