Wet powder spraying—a process for the production of coatings

Feasibility of glass–ceramic coatings on alumina prosthetic implants by airbrush spraying method

“…The present work addresses to the first of these two challenges, investigating the feasibility of a glass-derived coating by airbrush spraying of SiO 2 -CaO-Na 2 O-Al 2 O 3 (SCNA) glass powder suspensions followed by thermal treatment. Airbrush spraying of ceramic slurries is a versatile method that allows the coating of substrates having complex shape with an adequate control of coating thickness [17][18][19][20]; however, there is a paucity of studies about its use in the field of bioceramics. Very recently, Pardun et al reported the characterization of wet nanopowder-sprayed zirconia/HA composite coatings on dental implants (screws) [21].…”

Wollastonite-containing bioceramic coatings on alumina substrates: Design considerations and mechanical modelling

“…Airbrush spraying of ceramic slurries is a versatile strategy to produce coatings with good control of the thickness [17][18][19][20] and promising possibilities of scaling up from the "Lab scale" to industrial production. However, there is a relative paucity of studies concerning the layer-wise deposition of ceramic slurries for biomedical applications [21,22] and the full potentialities of this approach are still unexplored.…”

Magnesium-containing mixed coatings on zirconia for dental implants: mechanical characterization and in vitro behavior

“…The coatings were applied with the WPS technique, which suitability was already shown in previous works. 19,31 Since bone is a porous material, the obtained porous coatings represent a more natural morphology with varying pore sizes in order to facilitate cell anchoring and thus bone ingrowth. Moreover, Mg-addition was considered to increase the coating biocompatibility due to a more similar bone composition.…”
