Anodising, Electropolishing, and Pickling & Passivating

Benefits of Anodising, Electropolishing and Pickling & Passivating 

Anodising, Electropolishing and Pickling & Passivating are an essential part of our treatment process for all spun products and provide a range of benefits for many of the sectors we work with. 

Electropolishing 

Electropolishing is an electrochemical process that removes a controlled amount of material from a metal surface to improve its finish, cleanliness, and corrosion resistance. It involves immersing the metal in an electrolyte bath and applying an electrical current to create a smooth and shiny surface. 

Anodising 

Anodising is an electrochemical process that forms a durable oxide layer on the surface of metals. This oxide layer enhances corrosion resistance, provides a decorative finish, and allows for the colouring of the metal. Anodising is commonly used in various industries, including aerospace and automotive, to improve the properties of aluminium components. 

Pickling 

Pickling is a chemical process used to remove surface impurities, contaminants, rust, scale, and oxides from metal surfaces. It involves immersing the metal in an acidic solution to clean and prepare it for subsequent treatments or processes. 

Passivation 

Passivation is a chemical process that follows pickling, primarily used for stainless steel and other corrosion-resistant alloys. It forms a protective passive oxide layer on the metal’s surface, enhancing its corrosion resistance and maintaining its integrity in harsh environments.
