Before metal components leave production, we need to make sure they’re as good as they possibly can be. So, we use surface treatments on them to make sure parts will perform well and last for a long time. Let’s take a look at six metal surface treatments.
1-Electroplating
Electroplating is basically when we apply a thin layer of metal onto a surface using an electric current, which improves corrosion resistance, conductivity and visual finish.
2-Electroless plating
Similar in outcome but different in how it’s done, electroless plating uses a chemical reaction rather than electricity. This allows for a more even coating on complex shapes.
3-Hot dipping
When we immerse metal into molten coatings such as zinc, this is called hot dipping. This forms a really robust protective layer that’s used in outdoor or heavy-duty applications for long-term corrosion resistance.
4-Chemical treatments
Chemical processes like passivation or black oxide create protective films on metal surfaces, which can be used to improve corrosion resistance or prepare components for further finishing.
5-Anodising
Anodising, as seen here poeton.co.uk/surface-treatments/anodising, is mostly used on aluminium to create a durable oxide layer that helps to slow down corrosion and wear. It can also be dyed for a clean, consistent finish.
6-Thermal spraying
Thermal spraying applies molten or heated materials onto a surface to form a protective coating. It’s mostly used on larger components or where heat resistance is really important.
Together, these treatments give us a wide range of options depending what we need them for, which really helps extend the life and performance of our components.
