Protecting surfaces with smart coating solutions: A beginner's guide

 Wear, corrosion, and extreme temperatures are primary concerns in many industries. From machinery to pipelines to automotive components, exposure to harsh environments can cause damage over time. This is where thermal spray coating materials fit into the picture. They are applied to form a protective layer on surfaces, extending their life and enhancing their performance.

Thermal spray coating is not a technique but a series of techniques. It consists of spraying heated or melted material onto a surface to create a coating. The materials may be metals, ceramics, or polymers, depending on the industry. Such coatings are widely used in the aerospace, automotive, and manufacturing industries where resistance and durability are needed.

One of the most well-known techniques in this category is arc spray, which employs an electric arc to vaporise coating material wires. The resulting molten particles are blasted onto the surface with compressed air. Arc spray is best known for its affordability and use with a high surface area. It can also accommodate a broad assortment of materials, so it is a versatile option for most companies.

Advantages and Uses of Arc Spray Technology

Arc spray is particularly valuable when an immediate and consistent coating is required. It does not involve the use of high temperatures on the surface that is being coated, so it can be applied to heat-sensitive components. The technology is also fairly straightforward and can be mechanised for mass production.

When paired with the appropriate thermal spray coating materials, arc spray can be used to offer superior corrosion, wear, and even chemical exposure protection. In marine applications, for instance, metal components are usually coated against rusting. Machinery components in factories are coated to lower friction and increase efficiency.

The selection of coating material is crucial. There are materials that provide greater resistance to heat, whereas others are generally appropriate for corrosion prevention. Its success lies in the compatibility of the material with the particular requirements of the application.
