Production and Precipitation Hardening of Mg-Ca-Zn-Co Alloy for Tissue Engineering.
In this study, Mg-Ca-Zn-Co alloy specimens for biomedical applications were produced by the powder metallurgy method. The Mg-Ca-Zn-Co alloy could be used as a scaffold material in tissue engineering applications. Electrochemical corrosion behavior of the specimens was investigated in simulated body fluid environment. Electrochemical corrosion resistance of the specimens was increased with increasing Zn and Ca contents of the alloy up to an optimum composition and then decreased. Optimum values for Ca and Zn additions were about 0.7 wt.% and 3.0 wt.% respectively. Young's modulus values of the specimens were determined by nondestructive ultrasonic measurement. Alloying element addition increased the Young's modulus of the specimens. Precipitation hardening of the Mg-Ca-Zn-Co alloy increased the Young's modulus and the corrosion rate of the specimens.
期刊介绍：
Magnesium Research, the official journal of the international Society for the Development of Research on Magnesium (SDRM), has been the benchmark journal on the use of magnesium in biomedicine for more than 30 years.
This quarterly publication provides regular updates on multinational and multidisciplinary research into magnesium, bringing together original experimental and clinical articles, correspondence, Letters to the Editor, comments on latest news, general features, summaries of relevant articles from other journals, and reports and statements from national and international conferences and symposiums.
Indexed in the leading medical databases, Magnesium Research is an essential journal for specialists and general practitioners, for basic and clinical researchers, for practising doctors and academics.
