In recent years, zinc-nickel coatings have gained increasing attention due to their exceptional corrosion resistance, making them widely used in industries such as automotive, marine, and aerospace. Handheld X-ray fluorescence (XRF) spectrometers offer precise and reliable results for analyzing zinc-nickel coatings on iron substrates.
Zinc-nickel coatings are high-performance surface treatments commonly applied to components like fuel lines, fasteners, coaxial cables, connectors, and aluminum-to-steel joints. These coatings provide excellent electrical conductivity and outstanding corrosion resistance, even under harsh environmental conditions. They act as a protective barrier, preventing the underlying material from corroding. The performance of the coating is influenced by its thickness and composition—typically containing 10–15% nickel and 85–90% zinc. Proper control of these parameters ensures that the coated part meets its functional requirements while minimizing operational costs.
Zinc-nickel plating offers superior corrosion resistance compared to traditional galvanization. Coatings with less than 10% nickel content are easier to passivate and show more than three times the corrosion resistance of a similar thickness galvanized layer. On the other hand, coatings with around 13% nickel content are harder to passivate but offer the highest level of corrosion resistance, exceeding five times that of a comparable galvanized layer. This makes zinc-nickel coatings ideal for use in demanding environments across various industries, including automotive, marine, aerospace, defense, and light manufacturing.
