Six materials used in surface finishing

Surface finishing is something used to improve durability and performance in various industries, with different materials being chosen depending on what the part needs to withstand, for example, heat or corrosion.

Corrosion alone costs industry globally $2 trillion each year, of which £55 billion per annum is the cost to the UK.

Below are six commonly used materials and how they are typically applied in surface treatments.

Aluminium oxide

Aluminium oxide is one of the most widely used abrasive materials in surface treatment because it is hard and also effective for preparing surfaces before a coating is applied. Aluminium oxide is often used in both blasting and polishing processes, where a consistent finish is needed.

Silicon carbide

Silicon carbide is even harder than aluminium oxide, which makes it useful for cutting and grinding tougher materials. It is commonly used in precision finishing where a very smooth surface is required.

Chromium

Chromium is often applied through electroplating to improve corrosion resistance and appearance. It gives a shiny finish and is widely used in automotive and industrial parts.

Nickel

Nickel is valued for its protective qualities and is frequently used in plating processes. It helps improve resistance to wear and corrosion in demanding environments. Examples of surface treatments can be found at specialists like https://www.poeton.co.uk/surface-treatments/.

Zinc

Zinc is commonly used for galvanising steel. It provides a protective layer that helps prevent rust.

Ceramic coatings

Ceramic based materials are increasingly used in advanced surface treatments for high temperature environments. They provide strong protection against heat and wear.
