Abstract
Surface structuring by electron beam technique seems to be a
promising technique to produce a designed texture. The design of a
specific topography on the surface of the material can influence the
interaction with the biological environment. This work focuses on
the surface structuring and in vitro cytocompatibility of titanium
alloys. Commercial titanium grade 2 (TiGr2) and titanium alloy
Ti6Al4V are structured under vacuum by a high energy electron
beam. Structured figures are designed following different criteria
in order to develop a specific topography and roughness on the
surface. An additional modification on the surface is given by the
solidification rate after structuring. It changes the microstructure
near the surface and thus the mechanical properties. MC3T3-E1
osteoblast cells spread uniformly and build connections through
elongated filopodia on the structured surface, showing a polygonal
shape and proliferating after longer cultivation time. This
behaviour indicates an improvement of the cell condition.
