Surface microstructure and cell compatibility of calcium silicate and calcium phosphate composite coatings on Mg–Zn–Mn–Ca alloys for biomedical application

Surface modification of magnesium and its biodegradable alloys by calcium orthophosphate coatings to improve corrosion resistance and biocompatibility

“…Briefly, they comprise the following approaches: microstructure tailoring including both grain sizes (Hoog, Birbilis, Zhang, & Estrin, 2008;Wang, Estrin, & Z uberov a, 2008) and texture (Xin, Wang, Gao, Liu, & Liu, 2009), alloying (Chen, Kirkland, et al, 2012;Hort et al, 2010;Kraus et al, 2012;Song, 2007;Witte et al, 2006;Xin, Hub, & Chu, 2011), preparation of biocomposites Mensah-Darkwa et al, 2013;Razavi et al, 2010;Witte, Feyerabend, et al, 2007), surface treatment (Gu et al, 2011;Guan, Zhou, & Zheng, 2009;Majumdar, Bhattacharyya, Biswas, & Manna, 2008;Xue,Yun, Schulz, & Shanov, 2011;Zhang, Zhao,Wu, Wang, & Wu, 2007), and deposition of protective coatings (Chen, Kirkland, et al, 2012;Hiromoto, 2012;Hiromoto & Yamamoto, 2009;Keim, Brunner, Fabry, & Virtanen, 2011;Mensah-Darkwa et al, 2013;Gray-Munro, Seguin, & Strong, 2009;Nassif & Ghayad, 2013;Shadanbaz & Dias, 2012;Wang, Gao, Zhang, Zhou, & Wu, 2007;Wang et al, 2012;Wang, Wei, & Gao, 2009;Waterman et al, 2011;Xiao, Yu, et al, 2013). One should stress that, to improve the corrosion resistance, the surface of Mg and its alloys might be coated by both calcium orthophosphates only (the vast majority of the cited publications in this review) and calcium orthophosphate-based biocomposites (Abdal-hay, Barakat, & Lim, 2013;Du et al, 2011;Hahn et al, 2011;…”

Phosphate chemical conversion coatings on metallic substrates for biomedical application: A review

“…DCPD as an intermediate in bone mineralization has been widely used in biomedicine and dentistry [47]. Xu, Du et al [48][49][50] effectively utilized PCC process to form a porous and net like Ca-P coating which contains DCPD mainly on Mg alloys substrate ( Fig.2, Table 2). The results of in vitro cell experiments and in vivo implantations both indicated that DCPD coatings might be an effective method to improve the bioactivity of magnesium alloys.…”

Effect of Nano‐Zirconia on the Mechanical and Biological Properties of Calcium Silicate Scaffolds

“…[1][2][3] It could accelerate the formation of bone-like apatite in vitro and in vivo. 4,5 The new bone formation ability of CaSiO 3 scaffolds was significantly higher than that of calcium phosphate scaffolds in vivo. 6,7 In addition, silicon is an important trace element in bone.…”
