Alticolor's NADCAP-accredited treatment zinc nickel ensures superior resistance to corrosion and high temperatures, making it an excellent alternative to cadmium plating. Designed to provide your components with exceptional wear resistance, even under extreme conditions.
The zinc layer provides galvanic protection that prevents the base metal from oxidizing, while nickel increases the coating's hardness. Alticolor complies with the regulatory requirements for corrosion resistance of the Zinc-Nickel treatment as specified by AMS 2417K through in-house execution of the neutral salt spray test.
Zinc-nickel may introduce hydrogen, causing embrittlement of the treated component, particularly under torsional stress. Alticolor passes the hydrogen de-embrittlement test as specified by AMS 2417K.
This treatment is especially effective for components exposed to humidity, salinity, or aggressive chemical agents, such as those used in aerospace and marine applications.
Through the development of customized mounting methods, Alticolor ensures uniform coating even on components with intricate geometries.
Possibility of subjecting the component to subsequent mechanical processes, such as bending, without compromising its corrosion resistance.
Chromium trivalent-based passivation can be performed in transparent or black finishes, tailored to customer requirements.
Alticolor employs the Hull Cell to evaluate the parameters of the galvanic bath prior to performing the zinc-nickel process. This tool analyzes the coating behavior in relation to current density, monitoring uniformity, thickness, and quality of the deposit. It also identifies the optimal composition of the galvanic solution, ensuring compliance with technical standards and maximum reliability of the treatment.
Alticolor uses an XRF analyzer to measure the thickness and composition of the zinc-nickel coating, also determining the exact concentration of zinc and nickel in the bath. This instrument enables nondestructive and immediate analysis, ensuring continuous monitoring of treatment quality and compliance with required technical standards.
An electrolytic treatment combining zinc plating, which provides a protective layer against corrosion, and the application of nickel, a particularly durable and resistant metal. The process creates a uniform surface that is resistant to mechanical wear, chemical agents, and high temperatures.
Alticolor’s zinc-nickel process is fully automated and monitored by our Industry 4.0 system, ensuring a uniform coating application across the entire surface, including components with complex geometries and hard-to-reach cavities.
Alticolor has always been a trusted partner for companies requiring advanced treatments on metal components, providing effective solutions that comply with the highest industry standards.
Alticolor treatments undergo rigorous control procedures
