Production of high quality Ti-HAP functionally graded coating using well-controlled thermal plasmas

چکیده
Plasma sprayed hydroxyapatite (HAP) on metallic substrate have been used as medical implants. Generally, Ti-HAP Functionally Graded Coating (FGC) is made to improve the adhesion strength. In this paper, we make the FGC films under various experimental conditions. The adhesion strength, the Vickers hardness, c-axis orientation and the porosity of prepared FGC films are evaluated. The adhesion strength of FGC films has the necessary value to be used as artificial bones. We can control the porosity by varying input jet power and the mean diameter of HAP.

متن کاملNovel sphene coatings on Ti-6Al-4V for orthopedic implants using sol-gel method.
Hydroxyapatite (HAp) is commonly used to coat titanium alloys (Ti-6Al-4V) for orthopedic implants. However, their poor adhesion strength and insufficient long-term stability limit their application. Novel sphene (CaTiSiO5) ceramics possess excellent chemical stability and cytocompatibility. The aim of this study is to use the novel sphene ceramics as coatings for Ti-6Al-4V. The sol-gel method w...
