Electrochemical behaviour and analysis of Zn and Zn–Ni alloy anti-corrosive coatings deposited from citrate baths

“…To improve the corrosion resistance properties of steel in a harsh environment, significant efforts have been made to strengthen their anti-corrosive properties. 3,4 One of the ways to improve the corrosion resistant properties of zinc coating is to make alloys with Fe, Cu and Ni. According to the literature, 5,6 zinc alloy coatings such as Zn–Ni, 7–9 Zn–Cu 10 and Zn–Fe 11 alloy films are often used to provide excellent corrosion resistance and maintain strong mechanical properties for steel equipment.…”

Influence of chloride and pH on the pitting mechanism of Zn‐Ni alloy coating in sodium chloride solutions

“…[7] Zinc coating is well known in the automobile industry, and it is extensively adapted toward providing better corrosion resistance to mild steel in a corrosion environment. [8,9] Zinc can be alloyed with ferrous metals such as Fe, Co, Ni, and Mg to enhance the anti-corrosion property of the coated specimens. [7,10] A study has been conducted on the pitting corrosion of the metal alloy on the steel surface, and one of the analysis conducted on the Cu-Ni alloy pitting corrosion was reported by Jin et al [11] on various exposure times in a marine environment (30 C).…”

Preparation, characterisation, hardness and antibacterial properties of Zn–Ni–TiO2 nanocomposites coatings

“…Although pure zinc coatings continue to be used widely for the protection of steel from corrosion, considerable efforts are being made to improve their corrosion resistance for use in harsher environment. 1 One of the ways to increase the corrosion resistance of zinc coatings consists in alloying with Fe, Co and Ni. It was reported that Zn-Ni coatings provide cathodic protection to steel, exhibiting significantly higher corrosion resistance than pure zinc.…”
