Electrocodeposition of nickel–alumina nanocomposite films under the influence of static magnetic fields

Effects of magnetic fields on Fe-Si composite electrodeposition

“…Thus, the role of the field gradient force B  F is significant, and its effect should be considered in the electrodeposition process under an inhomogeneous magnetic field. According to Peipmann et al [18], a field gradient force ( B  F ) will be induced on the magnetic particles when a gradient of the magnetic field ( B ) exists:…”

“…Moreover, the magnetic field gradient force is considered to be another factor affecting the electrodeposition process [1617]. Peipmann et al [18] electroplated nickel with co-deposited Al 2 O 3 particles by electroless deposition of a thin nickel layer under magnetic fields and observed that the magnetized particles preferred to move to the nickel electrode surface under the field gradient force. At the same time, upward natural convection also can affect the deposition process [19].…”

Size Effect in Mechanical Properties of Nanostructured Coatings

“…The more volumetric percentage of alumina nanoparticles can be boosted in Ni/Al 2 O 3 nanocomposite coating the more provided hardness of nanocomposite coat can be expected. Hence, this activity requires getting familiarity with effective parameters in simultaneous electrical deposition process of alumina and nickel [38][39][40][41]. For this reason, electroplating variables and their effects in amount of participating alumina nanoparticles in coat will be studied in next part.…”

Nanocomposite Coatings: Preparation, Characterization, Properties, and Applications

“…The electrochemical codeposition of carbon nanotubes/conducting polymers has also been reported [126-129, 131, 134]. Other studies involved the electrochemical codeposition of oxide and metal nanoparticles, such as Ni (as matrix) and Al 2 O 3 (as nanofiller) [130,136]. Chitosan was also reported as a dominant organic matrix, used for the electrodeposition of nanocomposite coatings [125,132,133].…”

“…This method could be used for the fabrication of nanocomposite coatings, which contain organic nanofillers (such as PEO, PTFE [80,83,118]) or inorganic matrices [119][120][121][122][123] or organic matrices [19,22,32,78,124]. In the case of organic matrices, the electrochemical codeposition of nanocomposites has been reported by many researchers [123][124][125][126][127][128][129][130][131][132][133][134][135][136][137][138][139][140][141]. Zhitomirsky had reviewed the various nanostructured organic-inorganic coatings using electrophoretic deposition [140].…”
