Abstract
The main objective of this work is the design, preparation, and characterization of YSZ coatings by electrophoretic deposition (EPD) technique. The suspensions used for the preparation of zirconia-derived coatings by EPD have been thoroughly characterized. YSZ suspensions containing particles of different morphology and size have been used to optimize the electrophoretic characteristics of the suspensions. The correlation between the experimental results and the theoretical values predicted by the Hamaker's equation has been analyzed. Coatings have been thoroughly characterized. Surface morphology has been studied by Scanning Electron Microscopy. X-Ray Diffraction and Time of Flight-Secondary Ions Mass Spectrometry have been used to analyze the structure and composition of the samples. Finally, nanoindentation tests have provided information regarding the mechanical properties of the coatings. Optimal coating results were achieved using stainless steel substrates previously treated thermally so that a thin anchoring layer of chromium oxide was generated.
