Coating solutions

Metal coating is a critical process for improving the resistance of metals to abrasion, corrosion, and various environmental elements. Companies specializing in advanced technologies offer a variety of metal coating solutions, such as anodizing, alodine, and passivation. Each of the methods brings different benefits, depending on the customer’s needs and the specific requirements of the product.

Advantages of anodizing metal coatings

High corrosion resistance

Anodizing creates a thin oxide coating on the surface of the metal (mainly aluminum), which provides excellent resistance to corrosion and environmental elements such as water, acidity, and salts. The coating not only protects the metal from corrosion, but also extends its service life.

Mechanical reinforcement

Anodizing significantly strengthens the metal and reduces wear. The oxide layer not only protects but also increases the mechanical resistance of the metal, so it is less likely to peel or crack over time.

Rich aesthetics

The coating allows for the achievement of diverse and spectacular colors, obtained with the help of acidity and special dyeing methods. In addition, the color remains stable over time. And the abrasion resistance is high, making anodizing an ideal solution for aesthetic objects.

Non-toxic and environmentally friendly

The anodizing process does not include toxic substances in the final coating layer. The oxide layer formed is stable, inert, and does not emit substances hazardous to the environment or to human contact.

Maintaining aluminum properties

The anodizing process preserves the original properties of aluminum – strength, light weight, thermal resistance and structure. The layer is formed as part of the material itself and does not peel off or impair conductivity or the possibility of further processing. It is a durable and non-invasive solution that is suitable for precise industrial uses.

Advantages of Alodine coating

Corrosion protection

The alodine process creates a thin chemical layer on the surface of the aluminum, improving its corrosion resistance without impairing electrical conductivity. The layer protects the metal in humid or acidic environments and also serves as an excellent base for painting or other coatings.

Maintaining electrical conductivity

Unlike other coating methods, Alodyne allows the metal to retain its electrical conductivity. This is a critical advantage in electronic systems where high conductivity is needed without damaging the material’s structure.

Simple and effective process

Alodyne is a quick and easy process compared to other coating methods, providing quality solutions while saving time and production costs.

Protection in various thermal conditions

The Alodine process provides basic protection in moderate heat conditions, but is not intended for prolonged exposure to extremely high temperatures. In applications where extremely high thermal resistance is required, it is recommended to combine or choose other processes such as anodizing.

Advantages of passivation coating

Optimal protection against corrosion

Passivation is a particularly effective process for maintaining the corrosion resistance of metals such as stainless steel, which are characterized by frequent exposure to chemical elements or moisture. The coating creates a thin layer of passive material that insulates the metal and reduces the risk of oxidation damage.

Removing contaminants and strengthening the layer

Passivation improves the corrosion resistance of stainless steel by cleaning the surface and enhancing the natural protective layer, without changing the appearance or properties of the material.

Does not change the properties of the metal

Passivation does not change the properties of the metal, such as strength, flexibility, or resistance to mechanical stress. It only adds a layer that is almost invisible, so that the conductive properties of the metal are maintained.

A cost-effective and focused solution

The passivation process is economical, simple and effective. It provides a targeted solution in cases where there is a need to improve the metal’s resistance to aggressive conditions without affecting the other properties of the material.

Improves metal lifespan

Passivation extends the service life of the metal, making it an ideal solution for industries that require high resistance in harsh conditions, such as the food, healthcare, or chemical industries.

Each of the methods—anodizing, alodine, and passivation—provides its own advantages, depending on the customer’s needs, the environmental conditions in which the product will operate, and the aesthetic and physical requirements of the metal. Each method offers customized solutions that provide long-lasting durability and high efficiency in various applications.

Coating thickness: The coating is usually between 5 and 25 microns and gives the metal high mechanical resistance.
The thickness of the hard anodized coating: The coating is thicker (usually between 25 and 60 microns) and gives the metal greater mechanical resistance and abrasion resistance.
Color: One of the great advantages of anodizing is the ability to change the color of the metal (mainly aluminum and titanium) by adding different dyes to the process. The color remains very stable over time.
Effect on conductive properties: Anodizing creates an electrically insulating layer with a slight effect on heat conduction, but the aluminum maintains good thermal dissipation, and conductive areas can be left as required.

Main uses: automotive industry, optics, construction (such as aluminum profiles), military industry, electronics (such as components that deal with high abrasion).
Advantage: The thick layer of anodizing provides excellent resistance to corrosion and abrasion, and is therefore suitable for products that are subjected to strong mechanical stress and harsh environments.
