“…The desirable properties of these coatings may be attributed to increase in surface effectiveness or increase in interfacial regions [20,21]. It is of great importance to carefully control multilayer microstructures during the chemical deposition processes in order to obtain favourable tribological properties.…”

In the present work, multilayer Ni-Mo-Al 2 O 3 and Ni-Mo coatings were fabricated on the lowcarbon steel using pulse electrodeposition technique from a citrate-ammonia bath. The coatings with different number of layers (32, 128 and 512) were electrodeposited by the periodic alteration of duty cycle (between 20 and 90%) at a constant frequency of 400 Hz and an average current density of 6 A dm −2 . The corrosion resistance of the coatings was estimated using potentiodynamic polarisation and electrochemical impedance techniques and wear properties was also evaluated using pin-on-disk wear test. Potentiodynamic polarisation and electrochemical impedance in 3.5 wt-% NaCl solution showed that 128-layer nanocomposite coatings had the highest corrosion resistance. By increasing the number of the layers in Ni-Mo coatings, their hardness was improved from 563 ± 20 Hv 0.1 to 714 ± 42 Hv 0.1 , while the wear rate was decreased from 9.87 to 5.16 μg N −1 m −1 . The addition of nanoparticles showed favourable impacts on the coatings hardness and wear properties.

“…Electrodeposition has been used to prepare many types of nanostructured materials. [10][11][12][13][14][15][16] It is our goal to prepare nanostructured materials incorporating Sn by pulsed electrodeposition from a single, multicomponent plating bath along the lines described in Ref. 17.…”

Single-bath, pulsed electrodeposition of Cu-Sn alloy films was performed in a bath containing Lucent Technology’s SnTech plating solution and copper sulfate. Films with varying Cu-Sn stoichiometries were deposited. Deposited films were between ∼3 and 6 μm thick. These films were used as working electrodes in Li/Cu-Sn electrochemical cells to test their suitability as negative electrodes for Li-ion cells. As the Cu content in the film is increased, specific capacity is sacrificed for capacity retention. Films with a Cu-Sn atomic ratio of 0.27 (high Sn content) had a maximum specific capacity of 500 mAh/g, however capacity retention is only about 20% of the original capacity after 40 cycles. High Cu content films (Cu-Sn atomic ratio of 3.83) yield specific capacities near 200 mAh/g, with 80% capacity retention after 40 cycles. © 2003 The Electrochemical Society. All rights reserved.
