A Study of Zeta Potential of Plasma Sprayed Hydroxyapatite Coating in Four Simulated Physiological Solutions
The zeta potential magnitude and the duration of its changes have been thought to be directly related to the surface reactivity, the governing of osteoconductivity and availability of valuable information in determining the anticipated in-vivo performance of implants. In this study the zeta potential of plasma sprayed hydroxyapatite (HA) was evaluated in various simulated physiological solution...
متن کاملSplat Formation and Nanohardness Investigation of Atmospheric Plasma Sprayed Alumina
Atmospheric plasma spraying (APS) is a well established process for preparing ceramic coatings. In this process, powder particles injected into the plasma jet are heated and accelerated simultaneously in the plasma stream and are deposited in molten or semi-molten droplets conditions onto a prepared substrate. During droplet impingement, these molten droplets rapidly solidify to form single spl...
متن کاملCaO-P2O5 glass hydroxyapatite double-layer plasma-sprayed coating: in vitro bioactivity evaluation.
Double-layer composite coatings composed of a P2O5-based glass/Ca10(PO4)6(OH)2 (HA) mixture top layer and a simple HA underlayer, on Ti-6Al-4V substrates, were prepared using a plasma-spraying technique. The in vitro bioactivity of these coatings was assessed by immersion testing in simulated body fluid. Both scanning electron microscopy (SEM) analysis and the ionic solution changes followed by...
متن کاملCytotoxicity study of plasma-sprayed hydroxyapatite coating on high nitrogen austenitic stainless steels.
Stainless steel has been frequently used for temporary implants but its use as permanent implants is restricted due to its low pitting corrosion resistance. Nitrogen additions to these steels improve both mechanical properties and corrosion resistance, particularly the pitting and crevice corrosion resistance. Many reports concerning allergic reactions caused by nickel led to the development of...
متن کاملCharacterization of functionally graded hydroxyapatite/titanium composite coatings plasma-sprayed on Ti alloys.
Bioceramic coatings like hydroxyapatite (HA) have shown promising bioactive properties in load-bearing implant applications. The aim of this work is to deposit functionally graded HA/Ti layers consisting of an underlying Ti bond coat, the alternating layer, and an HA top-layer on Ti6Al4V substrates using plasma spray to improve the coating-substrate interface properties. The alternating layers ...
