Characterization of YSZ Coatings Deposited on cp-Ti Using the PS-PVD Method for Medical Applications

A patient’s body accepting a bone implant depends not only on the biomaterial used, but also its surface, which allows it to properly interact with cells. Therefore, research has focused improving bioactive and tribological properties of titanium alloys. Commercially pure (cp-Ti) is widely used as biomedical material. However, characterized by unsuitable properties. In this work, yttria-stabilized zirconia (YSZ) was deposited cp-Ti substrate via plasma spray–physical vapor deposition (PS-PVD). The structural characteristics were determined using X-ray analysis (XRD). Additionally, lattice parameters each phase Rietveld’s method. High-resolution scanning microscopy (HR-SEM) showed typical column structure coatings that can be PS-PVD. Depending process parameters, differed in thickness range 2.4–9.0 µm. surface roughness varied. samples subjected nano-indenter testing. slight change hardness after coating observed, addition significant decrease Young’s modulus. modulus relation metallic reduced 58 or 78 GPa depending spray-coating process.
