Języki publikacji
Abstrakty
The porous Ti13Zr13Nb alloy intended for load-bearing implants has been investigated. The alloy powder was obtained by plasma jet spraying a solid alloy sheet. Then the alloy granules were sintered by employing powder metallurgy, with and without a space holder, resulting in specimens demonstrating an open porous structure with a porosity up to 68% and mean pore size ranging between 30 and 150 μm. Further thermal, chemical and/or electrochemical oxidation caused increased corrosion resistance and the appearance of nanotubular titania layers after anodization, with nanotubes up to 2 μm in length and 80÷120 nm in diameter. The nanotubular layers were finally coated with deposits of hydroxyapatite obtained by using biomimetic or chemical (Alternate Immersion and biomimetic) methods. In conclusion, the employed surface techniques allow substantial improvement of the chemical stability, corrosion resistance, biocompatibility and bioactivity of the investigated titanium based biomaterial.
Przeprowadzono badania materiału porowatego, przeznaczonego na implanty ortopedyczne, wytworzonego metodą metalurgii proszków ze stopu Ti13Zr13Nb. Proszki z badanego stopu uzyskano metodą rozpylania plazmowego. Były one następnie spiekane bez lub z użyciem porogenu. Otrzymano próbki o otwartej porowatej strukturze, stopniu porowatości do 68% i średniej wielkości porów w przedziale od 30 do 150 mikrometrów. Obróbka próbek porowatych – utlenianie termiczne, chemiczne i/lub elektrochemiczne spowodowało otrzymanie krystalicznych lub nanorurkowych warstw tlenkowych, składających się z nanorurek o długości do 2 μm i średnicy 80÷120 nm oraz zwiększenie ich odporności na korozję. Nanorurkowe warstwy tlenkowe zostały następnie pokryte hydroksyapatytem metodą biomimetyczną lub chemiczną (przemiennego zanurzenia). Podsumowując, zastosowane techniki obróbki powierzchniowej pozwalają na znaczną poprawę stabilności chemicznej, odporności korozyjnej, biozgodności i aktywności biologicznej biomateriałów o osnowie tytanu.
