T1 - X-ray computed tomography of multiple-layered scaffolds with controlled gradient cell lattice structures fabricated via additive manufacturing T2 - IOP Conf. Series: Journal of Physics N2 - In this paper we report on the characterization by X-ray computed tomography of calcium phosphate (CaP) and polycaprolactone (PCL) coatings on Ti-6Al-4V alloy scaffolds used as a material for medical implants. The cylindrical scaffold has greater porosity of the inner part than the external part, thus, mimicking trabecular and cortical bone, respectively. The prismatic scaffolds have uniform porosity. Surface of the scaffolds was modified with calcium phosphate (CaP) and polycaprolactone (PCL) by dip-coating to improve biocompatibility and mechanical properties. Computed tomography performed with X-ray and synchrotron radiation revealed the defects of structure and morphology of CaP and PCL coatings showing small platelet-like and spider-web-like structures, respectively.  PB - IOP KW - Mechanical Engineering KW - Maskinteknik PY - 2019 UR - https://opus4.kobv.de/opus4-bam/frontdoor/index/index/docId/51076 AN - OPUS4-51076 UR - https://nbn-resolving.org/urn:nbn:de:kobv:b43-510763 SN - 17426588 VL - 1145 SP - 012044 AD - Bundesanstalt fuer Materialforschung und -pruefung (BAM), Berlin, Germany
