This research addresses the use of an emerging plasma spray technique known as SPPS (Solution
Precursor Plasma Spraying) to obtain bioactive glass coatings. In SPPS, the feedstock is a sol precursor of
the bioactive glass instead of glass particles. Precursor feedstock composition (presence or not of acid
catalyst), plasma torch enthalpy and stand-off distance of the spraying process have been varied to
produce bioactive glass coatings of nominally 45S5 composition. A good quality coating was obtained
when catalyst (0.2 M acid nitric) was used in the precursor and the plasma spraying took place with
shorter stand-off distance and higher plasma enthalpy. Bioactivity in Simulated Body Fluid test was
confirmed and an effect of the coating interconnected porosity to enhance bioactivity was observed. [-]
