Abstract
In this investigation, a pure magnesium ingot, tin, yttrium, zinc, and calcium granules were used to create the alloy Mg-3Sn-2Y-1Zn-0.6Ca. An electric resistance furnace was used to melt the alloy, and a gas combination with 4% sulfur hexafluoride and 96% argon was utilized to provide a protective environment. Scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS) and X-ray diffraction (XRD) were used to analyze the generated alloy’s phase and explore its microstructure. By using nanoindentation analysis, the nanohardness value (HN) and the decreased elastic modulus (Er) of the alloy were calculated. The alloy underwent tensile testing at body temperature of 36.5 °C. Immersion and potentiodynamic polarization experiments were performed in a salt solution at 36.5 °C to measure the alloy’s corrosion resistance. As a result of corrosion tests, the steady-state corrosion potential (Ecorr) and polarization parameters of the alloy were obtained.
在这项研究中，使用了纯镁锭、锡、钇、锌和钙颗粒来制造合金 Mg-3Sn-2Y-1Zn-0.6Ca。使用电阻炉熔化合金，并使用 4% 的六氟化硫和 96% 的氩气组合提供保护环境。使用扫描电子显微镜（SEM）、能量色散光谱（EDS）和 X 射线衍射（XRD）分析生成合金的相位并探究其微观结构。通过纳米压痕分析，计算了合金的纳米硬度值（HN）和降低的弹性模量（Er）。合金在 36.5 °C 的体温下进行了拉伸测试。在 36.5 °C 的盐溶液中进行了浸泡和电位极化实验，以测量合金的耐腐蚀性。通过腐蚀试验，获得了合金的稳态腐蚀电位（Ecorr）和极化参数。
期刊介绍：
The International Journal of Metalcasting is dedicated to leading the transfer of research and technology for the global metalcasting industry. The quarterly publication keeps the latest developments in metalcasting research and technology in front of the scientific leaders in our global industry throughout the year. All papers published in the the journal are approved after a rigorous peer review process. The editorial peer review board represents three international metalcasting groups: academia (metalcasting professors), science and research (personnel from national labs, research and scientific institutions), and industry (leading technical personnel from metalcasting facilities).
