Efficient Preparation of Nanoparticles Reinforced Nickel-based Composite Coating with Highly Preferred (220) Orientation
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).
