“…As the high cooling rate can suppress nucleation from the melts and the growth of crystallites, properly controlling the processing condition can keep both glass and crystalline phases in the coatings, thus forming glass -ceramic coatings. Additionally, it is worth noting that appropriately adjusting processing parameters can endow plasma-sprayed coatings with nanostructures [28,29], which have been proved to be beneficial for their biocompatibility [30 -33].…”

Glass -ceramics have attracted much attention in the biomedical field, as they provide great possibilities to manipulate their properties by post-treatments, including strength, degradation rate and coefficient of thermal expansion. In this work, hardystonite (HT; Ca 2 ZnSi 2 O 7 ) and sphene (SP; CaTiSiO 5 ) glass -ceramic coatings with nanostructures were prepared by a plasma spray technique using conventional powders. The bonding strength and Vickers hardness for HT and SP coatings are higher than the reported values for plasma-sprayed hydroxyapatite coatings. Both types of coatings release bioactive calcium (Ca) and silicon (Si) ions into the surrounding environment. Mineralization test in cell-free culture medium showed that many mushroom-like Ca and phosphorus compounds formed on the HT coatings after 5 h, suggesting its high acellular mineralization ability. Primary human osteoblasts attach, spread and proliferate well on both types of coatings. Higher proliferation rate was observed on the HT coatings compared with the SP coatings and uncoated Ti-6Al-4V alloy, probably due to the zinc ions released from the HT coatings. Higher expression levels of Runx2, osteopontin and type I collagen were observed on both types of coatings compared with Ti-6Al-4V alloy, possibly due to the Ca and Si released from the coatings. Results of this study point to the potential use of HT and SP coatings for orthopaedic applications.

“…In general the studied properties have been surface structure (Liu et al 1996, Bolelli et al 2005, Mateus et al 2005, hydrophilic properties (Watanabe et al 1999, Fujishima et al 2000a, Wu et al 2005, Fujishima and Zhang 2006, Pore et al 2006, Kronberg et al 2007) and crystallization (Llusar et al 2002, Romero et al 2003, Hsiang and Lin 2004, Jung and Park 2004, Bolelli et al 2006, Fröberg et al 2007a, Fröberg et al 2007b. In some studies it was reported that the manufacturing process affected crystallization and surface properties (Llusar et al 2002, Romero et al 2003, Hsiang and Lin 2004, Pore et al 2006, Fröberg et al 2007b.…”

“…Numerous techniques such as electrophoretic deposition, sol-gel, enamelling, laser deposition or thermal spray techniques have been employed to obtain such coatings. However, thermal spray techniques and more specifically Atmospheric Plasma Spraying (APS) is the most used method due to the high temperatures reached in the plasma torch and the subsequent fast cooling of the deposited material so that the devitrification of the as-coated glass is inhibited [3,4].…”

Bioactive glasses are emerging as a substitute of hydroxyapatite in the development of bioactive coatings for biomedical applications. The deposition of these coatings is carried out by a wide range of methods, being atmospheric plasma spraying the most employed technique. However, the research on the deposition of these coatings from suspension feedstocks by thermal spraying is still incipient, therefore more research about this topic is needed.Thus, a bioactive glass suspension, composed of fine glass particles, was prepared and stabilised through rheological and sedimentation tests to be used as a feedstock in plasma spraying. The solvent used in the suspension preparation was dipropylene glycol methyl ether in order to develop a new type of bioactive suspension. Consequently, as a new type of solvent was used, its effect on the plasma torch properties was determined. On other hand, the rheological behaviour of the suspension feedstock was assessed by means of a simple viscosity model. This suspension was deposited onto metallic substrates by plasma spraying, employing several spraying distances. All coatings displayed a suitable adherence and similar thickness.However, the microstructure of the obtained coatings is highly affected by the spraying distance as it can be seen in coatings surface and cross-section field emission gun environmental scanning electron microscopy examination. Thus, a relation between the spraying distance and coatings microstructure was found. On the other hand, X-ray diffraction confirmed the amorphous nature of the obtained coatings.
