    摘要:

    利用3D打印技術(shù)制作仿天然骨的多孔鈦骨科植入物具有廣闊的前景，等離子拋光技術(shù)作為表面技術(shù)的一種，可有效去除3D打印多孔鈦零件表面附著的顆粒物，降低表面粗糙度。本文分析了不同等離子拋光時(shí)間下多孔鈦零件外表面及內(nèi)層孔結(jié)構(gòu)外表面的表面形貌，并測(cè)量了其表面粗糙度值。通過(guò)實(shí)驗(yàn)可得，拋光時(shí)間越長(zhǎng)，表面越順滑，表面粗糙度值越低，拋光時(shí)間是影響表面粗糙度值的重要因素。根據(jù)拋光時(shí)間與表面粗糙度值的擬合曲線(xiàn)，得出了在保證零件內(nèi)外表面的表面粗糙度值在最優(yōu)值范圍下的拋光時(shí)間區(qū)間。

    Abstract:

    Porous titanium orthopedic implants fabricated by 3D printing have golden prospects. As one of the surface technologies, electrolytic plasma polishing can effectively remove the powder particles attached to the surface of 3D printed porous titanium parts and can reduce the surface roughness. In this paper, the surface morphology and surface roughness of the external and inner surface were analyzed and tested at different plasma polishing times. Electrolytic plasma polishing is effective to improve surface roughness. The longer the polishing time is, the smoother the surface is and the lower the surface roughness is. The polishing time is an important factor affecting the surface roughness. By the fitting curve, the surface roughness of the external and inner surface can be guaranteed to be within a reasonable range by the control of polishing time.
