[β- TCP/HA]在生物流体中多层涂层的摩擦学评价
生物医学或外科器械经历了许多骨结构修饰过程,这需要在生物流体环境中增强摩擦机械性能,以避免腐蚀过程。因此,以下研究对沉积在AISI 302钢上的[β-TCP/HA]n多层涂层的摩擦学响应进行了详细研究,以模拟生物流体中摩擦过程中的生物医学设备。力学研究确定,与具有1个双层的涂层相比,具有50个双层的涂料显示出26.3%的弹性模量和107.7%的硬度增加。随后,在干燥和生物流体环境(Hartmann溶液)中的摩擦学评估显示,当比较n=50双层和n=1双层时,摩擦系数分别降低了36.7%和43.5%。该研究得出结论,当用作生物医学设备上的保护涂层时,具有n=50双层的涂层优于n=1双层的涂层。
