The microstructure characterization and the cell compatibility of the Si-HA coatings were studied in comparison with that of hydroxyapatite (HA) coating prepared in the same way, The prepared Si-HA coatings and HA coating were only partially crystallized or in nano-scaled crystals. The introduction of Si element in HA significantly reduced P and Ca content, but densified the coating. The atom ratio of Ca to (P+Si) in the Si-HA coatings was in a range of 1.61-1.73, increasing slightly with an increase in the Si content. FTIR results displayed that Si entered HA in a form of SiO(4) unit by substituting for PO(4) unit. The cell attachment test showed that the HA and Si-HA coatings exhibited better cell response than the uncoated titanium, but no difference was observed in the cell response between the HA coating and the Si-HA coatings. Both the HA coating and the Si-HA coatings demonstrated a significantly higher cell growth rate than the uncoated pure titanium (p < 0.05) in all incubation periods while the Si-HA coating exhibited a significantly higher cell growth rate than the HA coating (p < 0.05). Si-HA with 0.42 at.% Si presented the best cell biocompatibility in all of the incubation periods. It was suggested that the synthesis mode of HA and Si-HA coatings in a simulated body environment in the biomimetic process contribute significantly to good cell biocompatibility.

The porous titanium had a complete three-dimensional (3D) interconnected structure and a high yield strength of 100 MPa. Si-substituted hydroxyapatite (Si-HA) was coated on the surface by a biomimetic process to improve the surface bioactivity. X-ray diffraction results showed that Si-HA coating was not well crystallized. New bone tissue was found in the uncoated porous titanium after 2 weeks of implantation and a significant increase (p < 0.05) in the bone ingrowth rate (BIR) was found after 4 weeks of implantation, indicating the good osteoconductivity of the porous structure. The HA-coated and Si-HA-coated porous titanium exhibited a significantly higher BIR than the uncoated titanium at all intervals, highlighting the better surface bioactivity and osteoconductivity of the HA- and Si-HA coatings. Also, the Si-HA-coated porous titanium demonstrated a significantly higher BIR than the HA-coated porous titanium, showing that silicon plays an active role in the surface bioactivity. For Si-HA-coated porous titanium, up to 90% pore area was covered by new bone tissue after 4 weeks of implantation in cortical bone. In the bone marrow cavity, the pore spaces were filled with bone marrow, displaying that the interconnected pore structure could provide a channel for body fluid. It was concluded that both the 3D interconnected pore structure and the Si-HA coating contributed to the high BIR. (c) 2009 Acta Materialia Inc. Published by Elsevier Ltd.

The surface structures of the coatings were characterized by X-ray diffraction, X-ray photoelectron spectroscopy (XPS) and Fourier transformed infrared spectroscopy (FTIR). Si substituted hydroxyapatite (Si-HA) coatings with different Si contents were deposited successfully on the titanium substrate by immersing the pretreated titanium substrate into silicon containing supersaturated solutions (SSS) with different SiO(3)(2-) concentrations. The pretreatment of the Ti substrate in a mixed alkaline (NaOH + Ca(OH(2))) followed by a heat treatment produced a 3D porous surface structure with rutile and CaTiO(3) as main phases, which contributed mainly to the fast precipitation and deposition of Si-HA. FTIR results showed that Si in the Si-HA coating existed in the form of SiO(4)(4-) groups. The cross-section microstructure was observed by scanning electronic microscopy and the shear strength was tested. The coating was about 5-10 mu m in thickness and no interval was observed at the interface between the coating and the substrate. Shear strength testing showed that Si-HA/Ti exhibited higher shear strength than HA/Ti due to the existence of the SiO(4)(4-) group in the coating. (C) 2008 Elsevier B.V.

The EDS (energy dispersive sepectroscopy) results show that excessive silicon accumulates on the surface of the steel substrate due to the low solubility of silicon in the Γ layer after the Fe layer is depleted by the increasing growth of the compound layers. With the movement of α-Fe/ Γ interface towards the substrate by the Fe/ Zn reaction, silicon-rich α-Fe peels off from the substrate and breaks into particles. The particles, much like an inert marker in a Kirkendall effect experiment, move towards the δ layer through the Γ layer because silicon-rich α-Fe can not be adsorbed in the Γ layer. On reaching the δ/ Γ interface, the particles quickly dissolve in the δ layer, and accelerate its growth, resulting in the gradual disappearance of the Γ layer. At the same time, the normal coating is quickly changed into coatings typical of reactive steels as silicon dissolved in the δ layer soon diffuses toward the ζ layer. A similar process may happen in the initial stage of galvanizing reactive steels on a small scale, although it is hard to be observed.","authors":[{"authorName":"C.S.

In the initial stage, necking, stubbing and fragmentation of silicon particles result in the improvement of plasticity of alloy. In the intermediate stage, the mechanical properties of 354 alloy attain peak values due to spheroidization of silicon particles. In the final stage, the drop of hardness and strength is related to the deterioration of silicon morphology. The facets and lap occur in silicon particles and the coarsening process of silicon follows LSW model. During aging, the clusters of excess silicon can work as barriers for dislocation movement and thus enhance the strength of alloy. On the other hand, excess Si affects the process of aging precipitation and leads to a fine and highly dense distribution of GP zones, finally effectively strengthens the alloy.","authors":[],"categoryName":"|","doi":"","fpage":"496","id":"07346861-b40d-41e2-93be-ebbc2e96f6e4","issue":"3","journal":{"abbrevTitle":"TONMSOC","id":"9449c409-0c62-400e-a51e-429b454dce51","issnPpub":"1003-6326","publisherId":"TONMSOC","title":"Transactions of Nonferrous Metals Society of China"},"keywords":[{"id":"69f60363-0f7a-4e63-aa7c-f632e4a56ad2","keyword":"Al-Si-Cu-Mg alloy;eutectic silicon;mechanical property;heat;treatment;quantitative metallography;phase","originalKeyword":"Al-Si-Cu-Mg alloy;eutectic silicon;mechanical property;heat;treatment;quantitative metallography;phase"}],"language":"en","publisherId":"1003-6326_2004_3_1","title":"Effect of heat treatment on eutectic silicon morphology and mechanical property of Al-Si-Cu-Mg cast alloys","volume":"14","year":"2004"}],"totalpage":385,"totalrecord":3846}
