摘要: 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.

Abstract: 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.

Key words: vacuum plasma spray, hydroxyapatite, coating, XRD analysis, SEM analysis
