Because of their exceptional hardness and corrosion resistance, nickel and its alloys are crucial engineering metals. In a variety of field applications, nickel metal with a functional surface offers numerous performance benefits. Therefore the preparation of nickel coatings with unique properties such as superhydrophobic, corrosive, and self-cleaning on nickel surfaces is widely considered in surface engineering.

Case 1: Ammonium chloride as a crystal modifier
For the fabrication of nickel coatings with a graded structural morphology, ammonium chloride as a crystal modifier is dded to the plating solution. The nickel surface can have a range of qualities due to this unique coating structure, including hydrophobicity and corrosion resistance.
Case 2: Al2O3 coating on nickel microbubbles
Metal microbubble surface coatings for gas-liquid-solid microfilled beds have received a lot of interest in recent years, owing to the benefits of microfilled beds, such as their compact size, large specific surface area, good mass and heat transfer performance.
Because of its high specific surface area, corrosion resistance, thermal stability, and chemical stability, Al2O3 powder is employed for the coating. Alfa Chemistry employed chemical etching to pretreat the nickel substrate surface, followed by slurry circulation to successfully prepare the monolithic catalyst coating, to increase adhesion between the coating and the foam metal substrate. The nickel microfoam coatings are likely to be utilised in catalytic processes in microfilled beds.
