采用等离子喷涂技术在钛（Ti）和CoCrMo植入体上制备了ZrO2（4%CeO2）和ZrO2（3%Y2O3）涂层，并对涂层的粘结性能、形貌和结构性能进行了评价。利用x射线衍射（XRD）、扫描电镜（SEM）、表面粗糙度、硬度和粘接强度对这些涂层进行了表征。XRD分析表明，两种涂层均为原始四方相。SEM观察表明，两种zro2涂层均表现为粗糙、多孔和熔融。涂层、涂层-衬底界面和未经酸蚀的衬底的横截面表面形貌非常致密和光滑。酸蚀后，与致密的zro2涂层- cocrmo衬底界面相比，zro2涂层- ti衬底界面内部出现了较薄的间隙。结果表明，等离子喷涂可能在涂层- Ti衬底界面形成了一层非晶态Ti层，该层可通过酸蚀去除。ZrO2（3%Y2O3）和ZrO2（4%CeO2）涂层的平均表面粗糙度与起始粉末尺寸和基体有关。所有涂层和基体的硬度均无显著差异。ZrO2（4%CeO2）涂层对Ti和CoCrMo基体的粘接强度均大于68MPa，明显大于ZrO2（3%Y2O3）涂层。
ZrO2(4%CeO2) and ZrO2(3%Y2O3) coatings were deposited on titanium (Ti) and CoCrMo implants using plasma spraying and the adhesive, morphological and structural properties of the plasma-sprayed coatings were evaluated. Characterization of these coatings was performed using X-ray diffraction (XRD), scanning electron microscopy (SEM), surface roughness, hardness, and adhesive strength. XRD patterns showed that both the coatings appeared to be primitive tetragonal phase. SEM observations showed that both the ZrO2coatings appeared to be rough, porous and melted. The cross-section surface morphology of the coatings, coating–substrate interfaces and substrates without acid etching was very dense and smooth. After acid etching, as compared to the dense ZrO2coating–CoCrMo substrate interfaces, the thin gaps appeared within the ZrO2coating–Ti substrate interfaces. It is suggested that plasma spraying probably formed an amorphous Ti layer in the coating–Ti substrate interface that can be removed by acid etching. The average surface roughness of ZrO2(3%Y2O3) and ZrO2(4%CeO2) coatings was correlated to the starting powder size and substrates. No significant difference between the hardness of all coatings and substrates was observed. The adhesive strengths of ZrO2(4%CeO2) coating to Ti and CoCrMo substrates were higher than 68MPa and significantly greater than that of ZrO2(3%Y2O3) coatings.
