Bioactive glasses are emerging as a substitute of hydroxyapatite in the development of
bioactive coatings for biomedical applications. The deposition of these coatings is carried out
by a wide range of methods, being atmospheric plasma spraying the most employed
technique. However, the research on the deposition of these coatings from suspension
feedstocks by thermal spraying is still incipient, therefore more research about this topic is
needed.
Thus, a bioactive glass suspension, composed of fine glass particles, was prepared and
stabilised through rheological and sedimentation tests to be used as a feedstock in plasma
spraying. The solvent used in the suspension preparation was dipropylene glycol methyl ether
in order to develop a new type of bioactive suspension. Consequently, as a new type of
solvent was used, its effect on the plasma torch properties was determined. On other hand, the
rheological behaviour of the suspension feedstock was assessed by means of a simple
viscosity model.
This suspension was deposited onto metallic substrates by plasma spraying, employing
several spraying distances. All coatings displayed a suitable adherence and similar thickness.
However, the microstructure of the obtained coatings is highly affected by the spraying
distance as it can be seen in coatings surface and cross-section field emission gun
environmental scanning electron microscopy examination. Thus, a relation between the
spraying distance and coatings microstructure was found. On the other hand, X-ray diffraction
confirmed the amorphous nature of the obtained coatings. [-]
