High Velocity Suspension Flame Spraying HVSFS

High Velocity Suspension Flame Spraying (HVSFS) 

Current trends in coating biomedical implants with osseoconductive nanostruc-tured hydroxyapatite coatings lean towards thin ( 50 pm) homogeneous layers that are able to maintain the roughened microstructure of the implant substrate conducive to cell attachment and to minimise residual stresses and thus reduce the risk of coating delamination. 

the processing of very fine-grained powders with a grain size in the nanoscale requires the development of new concepts. As submicrometre-and nanometre-sized powder particles cannot be processed using mechanical powder feeders, feedstock delivery is done by liquids in which solid particles 

Crystallinities of 10-70% were obtained, depending on the deposition parameters and the use of a Ti02 bond coat and can be adjusted by PDA beyond 450 °C.
