Hard anodising is a surface treatment applied to aluminium to ensure that the material is fit for purpose. The result is a uniform oxide surface layer that provides a greater degree of wear resistance to the aluminium, together with improved resistance to the environment. Hard anodising is widely used in many diverse applications where performance in service is a critical factor.
What Is Hard Anodising
Hard anodising is a process that creates a thick oxide layer on the surface of aluminium, improving hardness, abrasion resistance, and overall performance. Compared with standard anodising, it produces a much thicker coating, typically ranging from 20 to 100 microns.
Another key benefit is its strong resistance to corrosion, making it a suitable choice for components exposed to moisture or harsher environments.
For anyone wishing to learn more about hard anodising, specialists such as www.poeton.co.uk/surface-treatments/anodising/hard-anodising provide a wealth of information and advice.
Key Benefits of the Process
One of the main advantages of hard anodising is the surface hardness of the coating. When the part is hard anodised the surface hardness of the coating is increased. This means that the surface is less susceptible to wear and is less prone to scratching. This ensures parts that are subject to high levels of wear and abrasion are ideal for hard anodising.
It’s also seen as a cost-effective option compared to other treatments, as it helps extend the lifespan of components without the need for frequent replacement. On top of that, many hard anodising options meet modern environmental standards, which is an added benefit for many applications.
