| Abstract Scope |
A new method of aerosol cold spray (ACS) associated with following sintering is tried for Hydroxyapatite (HA) coating deposition on the pet implants. While aerosol cold spray technology has matured during the last decade, the complex effects of ceramic deposition parameters on porosity, mechanical properties and microstructure are unclear. The physical modelling of the structure formation processes is difficult because of lack of some technology parameters knowledge to enable a better fundamental understanding of both ACS and sintering process parameters. In this presentation, a new ACS apparatus is used to examine the ACS process. Sintering of coatings is made by two methods (spark plasma sintering and furnace sintering). Establishment and validation of the HA coating structure formation mechanisms is provided through experimental measurements which demonstrate the opportunities of new technology and its ability to provide considerable improvements of the HA deposition onto pet implants. |
