摘要:
通过熔盐电解的方法, 制备出了适用于骨骼3D打印用的非球形高纯钛粉, 其成本不到球形钛粉的十分之一。熔盐电解制备出的金属钛粉, 具有高比表面积和高纯的特点, 在进行骨骼3D打印的时候, 更容易形成多孔状, 而其高纯性更是保证了人体的健康。通过SEM分析钛粉的微观形貌, 研究了骨骼3D打印用非球形高纯钛粉的特点, 电解钛粉由于只存在一步的电沉积反应, 颗粒的生成非常有规律, 这也是电解钛粉虽然不是球形, 但却有着很好流动性的原因;通过循环伏安曲线, 分析了钛离子的阴极沉积过程, 确定了钛粉的沉积电位。
Abstract:
Nonspherical high-purity titanium powders were prepared by molten salts electrolysis for 3D skeletal printing,its manufacture cost is less than 10% of spherical titanium powders.Nonspherical titanium powders by molten salts electrolysis own the characteristics of high purity and specific surface area that can easily form porous structure in 3D skeletal printing,and the high-purity ensures the health for human body.The microstructure of nonspherical high-purity titanium powders was analyzed by SEM. Because only one step of electrodeposited reaction happened in the process of titanium powders preparation,the formed titanium particles were very uniform.That is why the morphology of electrolysis titanium powders was not spherical,but it still had good flowability.The process of electrodeposition of titanium ions was analyzed by cyclic voltammetry curves,and then the deposition potential of titanium powders was confirmed.
