How can we understand the term ‘metallization’? Which industries are metallization applied to?

Metallization is a thermal spray coating process in which metals such as zinc, aluminum, silver, etc. are deposited as a thin metal film on top of a base material such as plastic, glass, or metal to prevent corrosion of the base material.metallization 3 vivablastThe metallizing process consists of three main steps:

  1. The base material is prepared by abrasive or metal spraying to provide high adhesion to the metal being sprayed.
  2. Heat is used to generate molten particles from the coating material, which is then sprayed onto the surface.
  3. Once contacting, the particles spread evenly on the surface, freeze and create a mechanical bond, first with the roughened surface, and then with each other as the coating thickness increases.

The metal used to make the coating can be in the form of wire or powder. Coating thicknesses can vary from .004″ to thicker layers between .012″ – .014″.This technology is widely used to enhance the corrosion resistance of materials. The metallization process is applied in many industries, such as:

  • Defence
  • Oil and Gas
  • Solar energy products
  • Space
  • Automobile
  • Electricity

5 benefits that make metallization one of the most highly-recommended protection methods

1. Strengthen the corrosion resistance:

Rust is not new but still quite a serious problem of metal structures, especially steel. The metallization process can create a coating that protects the metal surface from the development of red or white rust, increasing the product’s longevity to 20 years or more.

2. Enhance the durability of the material

Most metal coatings are appreciated for their good adhesion. They are less prone to peeling, blistering, and cracking than uncoated surfaces. Since then, the durability of the surface of the material has also significantly improved.

3. Provide electrical conductivity

One limitation when using ductile materials is that they are not conductive. When a plastic surface is metalized, it can conduct electric current. This is a remarkable step forward in the electronics industry.

4. Provide weather resistance

Steel structures located outdoors are susceptible to the effects of snow, rain, wind and sun, leading to deterioration over time. Creating a metallized coating creates a protective shield for the underlying structure, which prolongs the life of the structure and maintains its appearance.

5. Save maintenance costs

With common paints, after a while, they are forced to be replaced by a new layer. Meanwhile, the metallized layer does not need repainting or maintenance, thereby reducing operating costs. Metallization coatings also have a diverse and beautiful color palette that is not inferior to conventional paints.metallization 2 vivablast

5 different methods of metallization: What are they and how do they make it work?

In general, the general principle of the metallization process consists of preparing the surface, then using high temperature to create molten particles and then spraying them onto the surface. But when it comes to details, we can divide the metallizing process into 5 different types:

1. Vacuum metallization

This is the process of boiling the coated metal in a special vacuum chamber, then letting it condense to form a residue on the surface of the substrate. Coated metal can be vaporized through plasma or resistance heating.

2. Hot-dip galvanizing

This process involves dipping the steel into a vat of molten zinc. Zinc reacts with iron in steel to form an alloy coating that helps resist corrosion. After the substrate is removed from the zinc bath, it undergoes a draining or vibration step to remove excess zinc. The galvanizing process will continue after the substrate is removed until it cools.

3. Zinc spraying

Zinc is a material that is both versatile and cost-effective, helping to prevent corrosion on metal surfaces. Zinc metallization is the process of creating a slightly porous, lower density coating than hot-dip galvanizing. Zinc spraying can be applied to all steels but is not recommended for uneven surfaces.

4. Thermal spray

Thermal spray is the process of spraying heated or molten metal onto the surface of the material. The metal is introduced in powder or wire form, then heated to a molten or semi-molten state and sprayed as microscopic particles. Thermal spray can produce thick coatings at high speed.

5. Cold spray

In the cold spray technique, a mixture of metal powder, water-based binder and hardener is sprayed onto the surface at room temperature to form a workpiece. The embryos are left for about an hour and then dried at temperatures between about 70°F and 150°F for 6-12 hours. This metallization technique provides durable and long-lasting corrosion resistance.
