Treating metal surfaces enhances durability and protects against corrosion. Additionally, it prepares metal components for use and keeps them working in harsh environments.
With so many options available, it makes sense to talk to a specialist such as https://www.poeton.co.uk/surface-treatments/. Here’s an outline of the most common surface treatments available today.
Mechanical treatments
Mechanical treatments are used to clean or prep a metal’s surface. Mechanical blasting is generally used to hide welds and scratches and improve coating adherence.
Laser technology
Once a nice-to-have, laser technology has become a go-to for speed and sustainability. Laser surface treatments deliver precise results with minimal waste and can be applied to virtually all metals. Laser technology is an energy-efficient alternative to mechanical methods of cleaning and texturing.
Chemical treatments
Chemical polishing is used to remove a thin surface layer. This process deburrs, polishes, and smooths the metal by removing surface flakes, damage and debris. Pickling, passivation and phosphating ensure that the surface is contamination-free, highly resistant to corrosion and doesn’t require further treatment.
Electrochemical techniques
Electroplating and anodisation are vital in the automotive and aerospace industries, where precision and durability are key. These finishing techniques improve corrosion and wear resistance, but can also be used to create a decorative finish.
Coating
Spraying provides a colourful, durable finish for everything from garden furniture to dental implants.
Aesthetic finishes
These treatments enhance the aesthetics of a metal without sacrificing its functionality. Colouring and texturising provide UV and salt-spray resistance while creating a non-reflective surface. Applications include kitchen appliances and architectural panels.
