Abstract
Ti6Al4V biomedical plates were fabricated by Laser Powder Bed Fusion using different process parameters. A slight influence of the laser energy density on mechanical properties and microstructure was revealed. Chemical etching allowed to make the surface of 3D samples uniform removing also spheres of unfused material. After etching some samples were anodized in calcium acetate and β-glycerolphosphate containing solution to grow a Ca and P containing porous TiO2 layers. The chemical etching improved the corrosion resistance of the alloy in simulated body fluid, while only after anodizing the alloys resulted to be corrosion resistant under inflammatory and severe inflammatory conditions.
对 3D 打印的 Ti6Al4V 生物医学板材进行表面处理，以增强其在模拟生理溶液和炎症条件下的耐腐蚀性能
使用不同的工艺参数，通过激光粉末床熔融技术制造了 Ti6Al4V 生物医学板材。结果表明，激光能量密度对机械性能和微观结构略有影响。化学蚀刻可以使 3D 样品的表面均匀一致，同时去除未融合材料的球体。蚀刻后，一些样品在含有醋酸钙和β-甘油磷酸酯的溶液中进行阳极氧化，以形成含有钙和磷的多孔二氧化钛层。化学蚀刻提高了合金在模拟体液中的耐腐蚀性，而只有在阳极氧化后，合金才能在炎症和严重炎症条件下具有耐腐蚀性。
期刊介绍：
Corrosion occurrence and its practical control encompass a vast array of scientific knowledge. Corrosion Science endeavors to serve as the conduit for the exchange of ideas, developments, and research across all facets of this field, encompassing both metallic and non-metallic corrosion. The scope of this international journal is broad and inclusive. Published papers span from highly theoretical inquiries to essentially practical applications, covering diverse areas such as high-temperature oxidation, passivity, anodic oxidation, biochemical corrosion, stress corrosion cracking, and corrosion control mechanisms and methodologies.
This journal publishes original papers and critical reviews across the spectrum of pure and applied corrosion, material degradation, and surface science and engineering. It serves as a crucial link connecting metallurgists, materials scientists, and researchers investigating corrosion and degradation phenomena. Join us in advancing knowledge and understanding in the vital field of corrosion science.
