Paper Title:
Bioceramic Coatings on Biomorphic SiC by Electrophoretic Deposition
  Abstract

In this research, bioactive glass powders were electrophoretically deposited on biomorphic SiC ceramic substrates. A post-deposition thermal treatment was carried out to improve the properties of the coatings. Particle size, surface morphology, composition and thickness of the coatings have been studied by Scanning Electron Microscopy (SEM), Energy Dispersive Spectroscopy (EDS) and interferometric profilometry respectively. The analysis demonstrated that the electrophoresis parameters, such as the voltage, the distance between the electrodes and the deposition time, play an important role on the thickness of the coatings. The post-deposition thermal treatment produces glass particles cohesion and leads to obtaining a homogeneous microstructure. The excellent coverage of the porous SiC surface morphology is also demonstrated. Finally, in order to assess the bioactive character of the glass coatings, in vitro test by immersion in simulated body fluid (SBF) was carried out.
