Surface treatments are used across manufacturing and engineering to improve durability, performance and appearance. Different processes are selected depending on the base material, operating environment and functional demands.

Anodising

Anodising is mainly used on aluminium to increase corrosion resistance and surface hardness. The process creates a controlled oxide layer that also allows for colouring, making it suitable for components that need both protection and a consistent finish.

Electroplating

Electroplating applies a thin metal coating, such as zinc, nickel or chrome, to improve corrosion resistance, conductivity or appearance. It’s often chosen for parts that require enhanced surface properties without altering the core material.

Heat treatment

Heat treatment modifies the internal structure of metals through controlled heating and cooling. It’s classed among surface treatments because it significantly improves hardness, strength and wear resistance in critical components.

Powder coating

Powder coating provides a durable, even finish that resists chipping and corrosion. It’s used for outdoor or high-contact items where a long-lasting protective layer is required alongside visual consistency. Here, you can find out more about powder coating.

Chemical conversion coatings

These treatments create a protective film through chemical reaction rather than material build-up. They’re used to improve corrosion resistance and adhesion before painting. Specialists such as https://www.poeton.co.uk/surface-treatments outline typical applications across industries.

Thermal spraying

Thermal spraying involves projecting molten or semi-molten material onto a surface to build up protective layers. It’s used for wear resistance, thermal protection and component repair in demanding environments.

Each method serves a specific purpose, supporting performance, longevity and reliability.
