Abstract


Metals can be coated with ceramic materials with the aim of improving their applications. Electrophoretic deposition (EPD) over a metallic substrate of zinc was used to produce these coatings, using Al2O3 slurries of several concentrations (5, 10 and 20 % in mass). The parameters which control the process were modified: electric intensity (10, 20 and 30 mA) and time (10 and 20 min). The nature of the electrolitic process determines a diffusion between the metallic and the ceramic materials, that may produce a variation of the properties of the final product. In order to detect and quantify the possible existence of that diffusion between the contact surfaces of both materials, a solid state laser of Nd:YAG (λ = 266 nm) coupled to an ICP-AES spectrometer was used. This has allowed to determine the evolution of zinc contamination for each of the variables assayed through the whole coating.
