“…This process can be seen as an effective strategy for preventing agglomeration and illustrates the mechanism behind the increasing content of Al 2 O 3 in the composite coatings. 13,14,20) 3.2 Effect of thiourea concentration on the mechanical properties of the composite coatings Figure 9(a) shows the correlations between the microhardness and the current density and thiourea content of the electrolyte. In the range of 200³500 A/dm 2 , the microhardness continues to increase with increasing current density up to 400 A/dm 2 .…”

CuAl 2 O 3 nanocomposite coatings were jet electrodeposited from an electrolyte containing Al 2 O 3 nanoparticles and added thiourea. The effects of the thiourea concentration on the surface morphologies, microstructures, growth structures, incorporated Al 2 O 3 nanoparticle contents, and mechanical performances of the composite coatings were examined. The results revealed that the adsorption of Al 2 O 3 increased from 4.6 at% to 9.3 at% with the addition of thiourea, and grain refinement from 61 nm to 33 nm was achieved. Thiourea additions in the concentration range of 015 mg/L increased the microhardness by 79% compared with that of the coating fabricated without thiourea. The mechanisms by which thiourea influenced the deposition quality and mechanical properties of the coating are discussed. [

“…Meanwhile, the agglomeration of the nanoparticles is broken up during the high-speed flushing, and the nanoparticles are distributed uniformly in the coating. Therefore, using jet electrodeposition to prepare nanoparticles reinforced composite coating, the advantages of high deposition efficiency, uniform distribution of nanoparticles and good surface quality of coating can be obtained [8][9][10].…”

Nanoparticles reinforced metal matrix composite coatings have great application potential in mechanical parts surface strengthening due to their excellent mechanical properties. This paper reports a phenomenon that the grain orientation gradually evolves to (220) with the deposition current density increasing when preparing nanoparticles reinforced nickel-based composite coatings by jet electrodeposition (JED). During the preparation of Ni-SiC composite coatings, the deposition current density increases from 180 A/dm2 to 220 A/dm2, and TC(220) gradually increases from 41.4% to 97.7% correspondingly. With the increase of TC(220), the self-corrosion potential increases from -0.575 V to -0.477 V, the corrosion current density decreases from 9.52 μA·cm2 to 2.76 μA·cm2, the diameter of corrosion pits that after 10 days of immersion in 3.5 wt% NaCl solution decreases from 278~944 nm to 153~260 nm, and the adhesion of the coating is increased from 24.9 N to 61.6 N. Compared with conventional electrodeposition (CED), the Ni-SiC composite coating prepared by JED has the advantages of smooth surface morphology, corrosion resistance and strong adhesion, which is more obvious with the increase of TC (220).

This paper reports a phenomenon that the grain orientation gradually evolves to (220) with the deposition current density increasing when preparing nanoparticles reinforced nickel-based composite coatings by jet electrodeposition (JED). During the preparation of Ni-SiC composite coatings, the deposition current density increases from 180 A/dm2 to 220 A/dm2, and TC(220) gradually increases from 41.4% to 97.7% correspondingly.The Ni-SiC composite coating with highly preferred (220) orientation has superior corrosion resistance and adhesion force. With the increase of TC(220), the surface roughness is reduced from Ra1.210 μm to Ra0.119 μm, the self-corrosion potential increases from -0.747 V to -0.477 V, the corrosion current density decreases from 54.52 μA·cm2 to 2.76 μA·cm2, the diameter of corrosion pits that after 10 days of immersion in 3.5 wt% NaCl solution decreases from 3.3~22.2 μm to 153~260 nm, and the adhesion of the coating is increased from 20.5 N to 61.6 N.The research results can provide theoretical and technical support for the preparation of new composite coatings with high efficiency, low cost, high adhesion and strong corrosion resistance.
