“…In this case, the surfactant in the bath not only plays a role of dispersing agent for PTFE particles, but also acts as a brightener for the Ni-PTFE composite film. 11) In contrast to the results which have been found by other researchers, 12) the inclusion of PTFE particles does not remarkably affect the surface morphology of Ni-PTFE composite film (Fig. 7(c)) in comparison with Fig.…”

Nickel/ultra-dispersed PTFE composite films with various PTFE content are electrochemically prepared from a Watt's nickel plating bath in which the PTFE particles (mean diameter 0.3 mm) are suspended using a cationic fluorocarbon surfactant. The microstructures of Ni-PTFE composite films are analyzed by means of XRD, SEM and TEM, and their water-repellencies are also measured. The results indicate that the PTFE particles take a homogeneous distribution within all the composite films. The PTFE particle content in the composite films is dependent upon the particle concentration in the plating bath and the plating parameters, and strongly influence the physical properties of Ni-PTFE composite films such as water-repellency. The contact angle of a water drop on the surface of composite film with maximum PTFE content of about 47.4 vol% reaches 154.9, showing a superior water-repellency.

“…Benea et al [35] showed that the incorporation of 20 nm SiC particles during Ni deposition modifies the impedance and cathodic polarization due to the modification of the surface morphology and crystallinity of the nickel matrix. Spinvalve-type multilayered structures in the form of nanowires were deposited by Fedosyuk et al [36] by pulsed ELD using a single electrolyte.…”

Nanostructured materials have gained importance in recent years due to their significantly enhanced properties. In particular, electrochemistry has a special role in producing a variety of nanostructured materials. In the current review, we discuss the superiority of electrochemical deposition techniques in synthesizing various nanomaterials that exhibit improved characteristics compared with materials produced by conventional techniques, as well as their classification, synthesis routes, properties and applications. The superior properties of a nanostructured nickel coating produced by electrochemical deposition are outlined. The properties of various nanostructured coating materials produced by electrochemical techniques are also described. Finally, the importance of nanostructured coatings in industrial applications as well as their potential in future technologies is emphasized.

“…[1][2][3][4][5][6] Composite electrodeposits have been prepared by dispersing particles in the metal matrices. The co-deposition mechanism of particles was reported to be composed of two steps, namely, the adsorption of metal ions on the particles and the subsequent reduction of the adsorbed ions on cathode surfaces.…”

Zn-Al 2 O 3 composites were electrodeposited from a non-suspended solution containing ZnSO 4 ·7H 2 O and Al 2 (SO 4 ) 3 ·14-18H 2 O using benzyldimethyltetradecylammonium chloride dehydrate (BDTAC) as the additive at an electrodeposition current of 50-500 A/m 2 with an air or a nitrogen bubbling. Initial layers with a thickness of approximately 1 µm were observed in the Zn-Al 2 O 3 composite on copper substrates. Furthermore, the Zn-Al 2 O 3 composite was composed of two different crystallographic areas, namely, nano-level size deposited grains with 20-60 nm in width and 100-200 nm in length, and closely packed fine particle deposits with a diameter of approximately 5 nm containing more than 26 atomic% aluminum. The nano-level size deposited grains and the closely packed fine particle deposits comprised nano-size ZnO and θ-Al 2 O 3 , respectively. The oxygen concentration in Zn-Al 2 O 3 composite by the air bubbling was higher than that in Zn-Al 2 O 3 composite by the nitrogen bubbling. In contrast, the zinc content ratio in Zn-Al 2 O 3 composite by the air bubbling was lower than that in Zn-Al 2 O 3 composite by the nitrogen bubbling. The aluminum concentration in closely packed fine particle deposits in Zn-Al 2 O 3 composite by the air bubbling was almost the same value as that in Zn-Al 2 O 3 composite by the nitrogen bubbling.
