dc.description.abstract
Among bioceramics, hydroxyapatite (HA) and tricalcium phosphates (TCP) are commonly used as bone replacement materials. Due to their similarity to the inorganic part of natural bone, they possess the ability to promote bone ingrowth and activate natural bone cells. However, these abilities depend strongly on their crystallographic phase which varies depending on the used sintering profile during manufacturing. For example, α-TCP is less stable than β-TCP or HA in acidic environment. Hybrid parts, consisting of HA and TCP in one part, may result in many different crystallographic phases. If these phases can be controlled during manufacturing of the hybrid part, this could lead to an implant which combines controlled integration into the natural bone with faster degrading phases while maintaining mechanical resistance in areas with slower degrading phases.
Electron backscatter diffraction (EBSD) allows a detailed analysis of crystallographic phases in a reasonably wide area (>10.000 µm). However, it also poses a challenge when used on non-conducting materials, like bioceramics, resulting in additional preparation steps.
Therefore, we would like to show our sample preparation for EBSD analysis of 3D-printed bioceramics and evaluate the EBSD results by analysing hybrid parts either manufactured in a two-material ceramic 3D-printing machine or manufactured via 3D-printing and subsequent sinter-joining. We will assess how EBSD analysis can give insight into crystallographic phases at interfaces of two materials in hybrid parts and highlight the advantages and disadvantages of using EBSD on bioceramics.
