Hydroxyapatite is a bioceramic material known as orthopedic implant due to its excellent biocompatibility. From a crystallographic aspect, HA is flexible and can accommodate different ions in its structure. Zinc (Zn) is essential in the human body due to its role in many biological functions and is known to have antibacterial properties. In this work, Zn doped hydroxyapatite coatings were developed by solution precursor plasma spraying using different zinc ion concentrations. It was found that zinc addition does not modify the morphology of coatings. X-ray diffraction analysis showed that Zn concentration greater than 10 mol% inhibits the formation of HA and favors the formation of calcium zinc phosphate. Rietveld refinement showed that the unit cell parameters were not substantially changed upon Zn addition. In general, the structural analysis revealed that Zn ions were highly likely inserted at the hydroxyl column formed by the dehydroxylation of HA under high-temperature plasma environment.

羟基磷灰石是一种生物陶瓷材料，因其出色的生物相容性而被称为骨科植入物。从晶体学的角度来看，HA是柔性的，可以在其结构中容纳不同的离子。锌（Zn）由于其在许多生物学功能中的作用而在人体中必不可少，并且已知具有抗菌特性。在这项工作中，通过使用不同锌离子浓度的溶液前驱体等离子喷涂技术开发了掺锌的羟基磷灰石涂层。发现锌的添加不会改变涂层的形态。X射线衍射分析表明，锌浓度大于10mol％会抑制HA的形成并有利于磷酸钙锌的形成。Rietveld精炼显示，添加锌后单位晶胞参数基本不变。一般来说，
