Surface finishing methods and post plating treatments are manufacturing techniques that impart protective and aesthetic qualities to metal products, helping them to withstand high temperatures, corrosion and wear. Choosing the right treatment requires careful consideration of the desired characteristics, budget and timelines.
What is the difference between surface finishing and post plating?
Surface finishing includes the use of processes such as sandblasting, grinding and polishing; techniques designed to produce the desired texture and appearance of a product.
Post plating is a secondary process that enhances the product’s natural characteristics. Many post plating treatments use chemicals to encourage the development of an oxide layer, improving the product’s corrosion resistance, durability and strength.
What are the key things to know about post plating treatments?
Many companies that perform surface treatments, such as //www.poeton.co.uk/surface-treatments/anodising/, can also perform post plating treatments.
The main post plating treatments available are passivation, in which an acid solution creates a passive oxide layer on the product; coating, in which a protective barrier is applied using one of a number of different application techniques; and anodising, which is an electrochemical process that transforms the surface of the product.
Not all post plating treatments can be used in all instances, as the surface finishing method chosen will affect the quality of the finish and the success of the post plating treatment. As the surface finishing method will affect the characteristics of the product’s surface, in terms of topography, cleanliness and smoothness, a compatible post plating treatment must be selected to ensure a high quality, durable and lasting finish is achieved.
