“…Pure nickel films have been widely employed for their corrosion resistance [7,8], this property can be combined with the mechanical properties of alumina to produce Ni-Al 2 O 3 composite films exhibiting enhanced hardness [6, and wear resistance [9,13,16,22,25,26,[28][29][30][31] whilst maintaining the corrosion resistance of nickel [ [18], 321, [33,34]]. Whilst there is a considerable amount of literature available on this composite material a systematic investigation of the main deposition parameters has not been considered in detail.…”

Nickel-Al 2 O 3 composite coatings have been successfully deposited galvanostatically on to stainless steel substrates by electro co-deposition from a Watts bath containing between 50 and 150 g/l of sub-micron or nanosized alumina particles applying current density of -10, -20 and -32 mA cm -2 . The alumina distribution in the composite films on the two sides of the substrate was remarkably different due to solution hydrodynamics and electric field effects. The effect of current density, particle concentration in the bath and particle size are studied systematically producing a comprehensive set of data for better understanding the effects of these variables on the amount of particles co-deposited. The amount of Al 2 O 3 co-deposited in the films increases with the particle concentration in the bath and strongly depends on the current density and on particle size. The effect of the current density and of the alumina inclusions on the crystallinity of the Ni matrix and on the Ni crystallites grain size has also been studied. The inclusions of nano or sub-micron-Al 2 O 3 particles are found to strongly influence the metallic nickel microstructure.

“…These failures are relevant in many industrial applications from bearings to turbine blades or heat exchangers for power generation [36] and in the same way in miniaturized mechanical, optical and electronic devices. Studies on nickel dispersion coatings give evidence that strengthening by micron-und submicronscaled particles of Al 2 O 3 , SiC or diamond is more effective than strengthening by Si 3 N 4 or TiO 2 [27,37,38]. The friction coefficient is conditioned by the content and size of incorporated particles.…”

Abstract. Electroplated nickel coatings provide ductility, excellent corrosion resistance and good wear resistance, which qualifies them to meet complex demands of engineering, microtechnology and microelectronics. The co-deposition of particles is a promising alternative to deposit layers with adequate microstructure and properties avoiding the rise of residual stress. The incorporation of the sufficient quantity of particles, monodisperse distribution and downsizing to nanometre scale affect the amount of strengthening by dispersion hardening. To avoid agglomeration in the electroplating bath as well as in the layer is a challenge which has been met by simple Watts nickel electrolyte with a minimum of organic additives and adequate bath agitation comprising sonication, i.e. the exposure of the bath to high-frequency sound waves.Well-dispersed hard particles (titanium oxide and silicon carbide) were incorporated in nickel films. The focus was set on the correlation between the gained microstructure of the composites with particles from micron to nanometre scale and the electrochemical and mechanical properties. Corrosion was quantified from polarisation curves and volumetric erosion measurements. Wear resistance was evaluated by scratch energy density studies, oscillating sliding wear testing and cavitation wear testing and compared to indentation hardness results.Sonication and particle downsizing result in matrix grain refinement and dispersion hardening. Incorporation of different particles with respect to different material and size proved to meet different demands. Submicron TiO 2 is best for high corrosion resistance, sonicated nickel without particle incorporation is best for high abrasion resistance, nano TiO 2 is best for oscillating sliding wear resistance and submicron SiC is best for cavitation wear resistance.

Bamboo is a typical natural composite material, and its special structure and excellent properties provide important information for the biomimetic design of composites. To strengthen the fiber content of bamboo distributed in a gradient, a bimimetic nano-Al 2 O 3 composite coating was designed and prepared on the surface of metal parts using a nanocomposite electrodeposition method. The optimal technology parameters were obtained, such as current density, PH value, nano-Al 2 O 3 content in electrolyte, and style of stirring etc after the experiments. The microstructure of the biomimetic nanocomposite gradient coating was very dense, and the contents of nano-Al 2 O 3 were distributed in the gradient. The microhardness of the composite coating changed from the surface to the inside in the gradient also. Moreover, the wetting angle between water and composite coating obviously increased and reached 97°at room temperature.
