Recubrimientos de circonia depositados por electroforesis sobre acero 316L

Abstract

The present research involved zirconia coatings prepared using electrophoretic deposition (EPD) on 316L stainless steel, via hydrolysis of ZrOCl$_{2}$ aqueous solution. Initially, a first zirconia thin film was obtained and treated at 400 $^\circ$C for consolidation. Then a second zirconia film was deposited to obtain a homogeneous and fully covered 316L stainless steel plate. The XPS analyses show that on the first zirconia film, the elements Fe, Cr, O and Zr are present. In this first film the compounds Cr$_{2}$O$_{3}$, Fe$_{2}$O$_{3}$ and ZrO$_{2}$ are formed. While in the second film only the Zr and O are observed so that the surface is formed by ZrO$_{2}$.
