Formation of Electrodeposited Ni‐Al ₂ O ₃ Composite Coatings

Effect of applied current on the electrodeposited Ni–Al2O3 composite coatings

“…It is thought that the nano-sized particles are lighter in weight, and therefore, more prone to be suspended in the coating bath during the coating process and this could help achieve a more uniform distribution with a greater concentration of particles in the coatings. In recent years, research on the formation of Ni-Al 2 O 3 composite coatings containing nano-sized (30-100 nm) particles using different coating techniques [7][8][9][10][11][12][13][14][15] have focused on the effect of particle size, amount of particles in the electrolyte on the dispersion behavior of ceramic particles in the coatings. However, the quality of the electrodeposited composite coatings will also depend on the coating parameters used during the electrodeposition process among which current density plays an important role in controlling the deposition rate which will in turn affect the concentration of incorporated particles in the coatings.…”

High Temperature Oxidation Behaviour of Nickel Based Nanostructured Composite Coatings

“…The surface was then cleaned with alkaline and acidic solutions to remove any remaining grease and contaminates. The bath solutions and the concentration of chemicals and oxide powders were obtained from the previous research [9,[22][23][24][25][26]. The characteristics of electrodepositing bath solutions are provided in Table 1.…”

The Role of Ni(II) Ion Adsorption onto TiO₂ in the Electrodeposition of Composite Ni-P+TiO₂ Coatings

“…Amongst many metal matrix used, Ni [2][3][4][5] and its alloys with W [6], Co [7,8], Fe [9], Mo [10] or P [11][12][13][14], has featured strongly. The dispersed phase most often are carbides (WC, TiC, SiC) [3,8,9,[12][13][14][15][16][17][18][19], graphite carbon [1], nitrides (Si 3 N 4 , AlN) [20], sulfides (MoS 2 ) [6,7], metal oxides (Al 2 O 3 , ZrO 2 , TiO 2 , NiO, La 2 O 3 ) [1,4,5,[21][22][23][24][25][26][27][28][29][30], boron [31,32], and recently also metal powders (W, Al, Ti, Mo, V, Co) [33][34][35][36][37][38...…”
