Ceramic Coating on Metal Substrate by Electrophoretic Deposition Assisted by Sweeping Flow in Aqueous Suspension

Abstract:

Article Preview

Silica coatings were fabricated on stainless steel substrates by electrophoretic deposition (EPD) of aqueous slurries. An cationic surfactant, polyethylenimine (PEI) was used for obtaining positively charged silica particles and coatings on the cathode in order to prevent the anode elution. In addition, in order to prevent formation of cracks in coatings on metal substrates after drying, polyvinyl alcohol (PVA) was added in slurries as a binder. Furthermore, we could obtain crack free coatings after drying by aqueous EPD assisted by sweeping flow.
