“…corrosion in 3.5 wt% NaCl by polarization curves and microhardness, also show an improvement. The preferred orientation of the Ni-P grain growth and an increased compactness of the deposit can be achieved using a combined electromagnetic-ultrasonic field (Zhou et al, 2016).…”

Ultrasound waves generate and enlarge gas cavities in an aqueous solution by compression and rarefaction cycles. When cavities have grown to a certain size they become unstable and collapse under external pressure. This process leads to a number of effects such as standing waves, microjetting, localized temperature increases etc., which can have a positive effect on electrochemical and chemical systems. In this chapter research studies concerning electroless nickel (Ni) deposition by ultrasound are reviewed. The main benefits of using ultrasound assisted electroless Ni deposition include (1) increased rate of deposition, (2) modification of coating morphology (3) modification of coating composition (4) dispersion of particles for composite deposition and formation of core-shell particles and (5) improved coating uniformity on complex structures.

“…It is reported in literature that addition of nano particles in the binary plating bath enhances the mechanical properties of the composite coating [22][23][24][25][26][27][28]. Over the years, Ni-P composite coatings with nano ZnO, TiO 2 , Ti, WC, h-BN, SiO 2 , SiC and Al 2 O 3 have been studied by several researchers [29][30][31][32]. Dense, uniform, crack free coatings with higher protection against corrosion were obtained by the incorporation of nano particles.…”

Electrochemical investigations were carried out on the Ni-P/nano cubic-Boron Nitride (c-BN) coatings obtained by using sodium hypophosphite reduced electrolyte bath solution with complexing agents. The screening of complexing agents was carried out by UV-Visible spectrophotometric studies. The deposits obtained using optimized bath composition was tested by EDAX, SEM and XRD in order to understand the structural morphology of the coatings. Electrochemical studies conducted by Potentiodynamic polarization and Electrochemical Impedance Spectroscopy (EIS) reveled the greater stability of coatings in acidic and alkaline environment. To evaluate the behavior of the coatings in marine environment, Salt spray test was conducted using sodium chloride solution. Results indicate the improved resistance to corrosion with the incorporation of nano c-BN in the coatings.
