Electrolytic Co-Deposition Mechanisms, Texture Layers, and Residual Stresses in Nanocomposite Coatings Processes: A Review ()
ABSTRACT
The composite coating has gained wider attention due
to its property to protect materials used in energy, bridges, offshore
platforms, underground pipelines, and the
aviation industry from corrosion and deterioration. In this work, a literature review was conducted about the
processes of nanocomposite coating,
the mechanisms of electrolytic co-deposition, the texture of layers, and the
residual stresses. An important aspect, residual stress, was emphasized, which
represents the persistent stress after removing the external force affecting
a metal in the plastic region. Because it
cannot be measured directly and may be determined by measuring strain and
indirect methods, the sources and methods for measuring residual stresses (XRD,
SEM, TEM, EDS) were described in the last section to provide a
comprehensive overview. Based on the thorough analysis of the published
literature, it was concluded that nanoparticles could be electrodeposited with
Ni on an Al substrate using a direct current and Ni sulfamate as an
electrolytic solution, and Nickel will not reside on the oxide layer covering
Al, so chemical changes are needed to prepare the Al surface. In addition,
texture changes with the thickness of the coated layer must be investigated.
