Many metal and industrial products are exposed to moisture, chemicals, heat, and friction during their lifetime, which can cause damage – but surface treatments help protect these materials, extending their lifespan.
1 . Powder Coating
Powder coating is a process in which powdered paint particles are sprayed onto a surface using an electrostatic charge. Powder coating is popular because it produces a thick, even coating that is resistant to scratches, chipping, fading, and corrosion.
2. Anodising
Anodising is an electrochemical process mainly used on aluminium, converting the material into a durable oxide layer that becomes part of the metal itself rather than sitting on top of it. Anodising also allows dyes to be absorbed into the surface, making coloured anodised finishes possible.
3. Electroplating
Many industries use surface treatments, such as at https://www.poeton.co.uk/surface-treatments/, to improve the corrosion resistance and appearance of metal products. Electroplating is a popular process of coating one metal with a thin layer of another metal using electric current.
4. Galvanising
Galvanising is a protective process in which steel or iron is coated with zinc to prevent rusting. Even if the surface is scratched, the zinc still protects the underlying steel because zinc corrodes before steel does.
5. Painting Coating
Painting and liquid coating involve applying liquid paint or protective coatings onto a surface.
6. Brushing and Polishing
Brushing and polishing are mechanical finishing processes that improve the texture and appearance of a surface. As well as improving appearance, polishing can also reduce surface roughness and improve cleanliness in industries such as food processing and medical manufacturing.
