“…12 Migration of ionic species can be reduced, comparing to conventional materials, through coating of titanium-based materials with zirconium, niobium or tantalum. 13 Fabrication of titanium-based materials by the anodic oxidation under spark discharge materials considers not only use of different materials but also various electrolytes. In that way surfaces get enriched with other ions as a heritage from the solutions applied thus leaving less possibility for the migration of titanium ions.…”

Three new porous zirconia-coated titanium materials using anodic plasma-electrochemical oxidation have been fabricated and characterized by scanning electron microscopy, electron probe microanalysis and X-ray diffraction. These ZrO2/TiO2 surfaces contained up to 43 wt% of ZrO2, 49 wt% TiO2 ( M1: - M3: ) and 8 wt% P2O5 ( M2: , M3: ). Zirconium titanate was detected as dominant microcrystalline phase. Primary human osteoblast cells were used for in vitro investigations. Cell proliferation and immunohistochemical analyses of morphology and expression of bone sialoprotein and osteocalcin were performed. Novel coatings M2: and M3: were shown to induce proliferation and expression of osteocalcin and bone sialoprotein to the extent comparable to that of Ticer, a material already employed in clinical practice.

Amorphous Carbon Coatings for Total Knee Replacements—Part I: Deposition, Cytocompatibility, Chemical and Mechanical Properties

et al. 2021

View full text Add to dashboard Cite

Diamond-like carbon (DLC) coatings have the potential to reduce implant wear and thus to contribute to avoiding premature failure and increase service life of total knee replacements (TKAs). This two-part study addresses the development of such coatings for ultrahigh molecular weight polyethylene (UHMWPE) tibial inlays as well as cobalt–chromium–molybdenum (CoCr) and titanium (Ti64) alloy femoral components. While a detailed characterization of the tribological behavior is the subject of part II, part I focusses on the deposition of pure (a‑C:H) and tungsten-doped hydrogen-containing amorphous carbon coatings (a‑C:H:W) and the detailed characterization of their chemical, cytological, mechanical and adhesion behavior. The coatings are fabricated by physical vapor deposition (PVD) and display typical DLC morphology and composition, as verified by focused ion beam scanning electron microscopy and Raman spectroscopy. Their roughness is higher than that of the plain substrates. Initial screening with contact angle and surface tension as well as in vitro testing by indirect and direct application indicate favorable cytocompatibility. The DLC coatings feature excellent mechanical properties with a substantial enhancement of indentation hardness and elastic modulus ratios. The adhesion of the coatings as determined in modified scratch tests can be considered as sufficient for the use in TKAs.
