Abstract

ESPITIA-CABRERA, I. et al. Recubrimientos de circonia depositados por electroforesis sobre acero 316L. Rev. mex. fis. [online]. 2005, vol.51, n.3, pp.311-315. ISSN 0035-001X.

The present research involved zirconia coatings prepared using electrophoretic deposition (EPD) on 316L stainless steel, via hydrolysis of ZrOCl₂ aqueous solution. Initially, a first zirconia thin film was obtained and treated at 400 °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 Cr₂O₃, Fe₂O₃ and ZrO₂ are formed. While in the second film only the Zr and O are observed so that the surface is formed by ZrO2.

Keywords : Zirconia; electrophoretic deposition; coatings; XPS.
