Characterization of Electrodeposited Gels on the TungSten Heater Coil

Formation of Composite Coatings of Layered Double Hydroxide Particles and Hydroxide Gel by Electrophoretic Deposition on Mg Alloy and Corrosion Resistance

“…It was reported that Mg and Al ions in the suspension precipitate as Mg and Al hydroxide gel during EPD. 21,22) Water reduction reaction continues to occur on the substrate surface during EPD, indicating that the initially precipitated Mg and Al hydroxides continues to be exposed to a high pH environment in the presence of NO 3 ¹ ions. It is thus highly expected that the precipitated Mg and Al hydroxides transformed to MgAlLDH having nitrate ions (LDH-NO 3 ).…”

“…1820) In our work, to glue the particles to substrate surfaces, hydroxide gel was intended to electrodeposit as an adhesive by adding metal ions to the suspension. 21,22) Metal ions (M n+ ) like Mg and Al ions in EPD suspensions precipitates as hydroxides (M(OH) n ) because pH on the cathodically polarized substrate surface rises by water electrolysis according to the following reactions.…”

Low‐Temperature Electrochemical Synthesis of ZrO2 Films on Zirconium Substrates: Deposition of Thick Amorphous Films and in situ Crystallization on Zirconium Anode

“…T HE preparation of functional ceramic coatings and powders using electrochemical methods is a relatively new technology that takes advantage of the large amount of literature available on metallic corrosion and electrodeposition. [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16] There are several oxide film deposition techniques, including physical deposition processes, such as vacuum deposition and sputtering using metal or oxide targets, and chemical deposition processes, including spray coating, dip coating, and sol-gel techniques. In these coating techniques, an amorphous film usually is deposited.…”

“…[9][10][11] The synthesis of ceric oxide powder was demonstrated by Switzer 1 using the cathodic method. Using a combination of the cathodic method and electrophoretic deposition followed by heat treatment, glass coatings on steel substrates, 13 glass coatings on silicon substrates, 14 and Al 2 O 3 coatings on tungsten wire 15,16 also were demonstrated. ZrO 2 is an important ceramic material for structural and electrical applications, including catalyst supports, oxygen sensors, thermal barrier coatings, and transformation-toughened materials.…”
