abstract = {Highly-porous titanium was produced by metal injection
molding (MIM) of feedstock containing potassium chloride
particles as a space holder. Macroporosity was generated by
dissolving the potassium chloride particles in water.
Challenges for MIM of highly-porous parts include shape
retention during debinding and sintering and achieving open
surface porosity. This study demonstrates that plasma
treatment can remedy both these effects for highly-porous
titanium. Plasma treatment of unsintered MIM samples enables
attaining porosities of up to $64\%$ in combination with
good dimensional accuracy. The effect of plasma treatment on
the uptake of interstitial impurities, dimensional accuracy,
sintered microstructure and porosity, as well as the
interaction of the plasma with partially-debinded MIM
samples, was investigated. Highly-porous titanium produced
by MIM and plasma treatment is attractive for biomedical
implants due to its low impurity content, good dimensional
accuracy and shape stability in combination with enhanced
open porosity, the latter contributing to bone ingrowth and
implant fixation.},
