Anodising

Anodising, or anodizing, is an electrolytic passivation process used to increase the thickness of the natural oxide layer on the surface of metal parts.

Anodising increases corrosion resistance and wear resistance, and provides better adhesion for paint primers and glues than bare metal. Anodic films can also be used for a number of cosmetic effects, either with thick porous coatings that can absorb dyes or with thin transparent coatings that add interference effects to reflected light. Anodising is also used to prevent galling of threaded components and to make dielectric films for electrolytic capacitors. Anodic films are most commonly applied to protect aluminium alloys.

Anodisation changes the microscopic texture of the surface and can change the crystal structure of the metal near the surface. Coatings are often porous, even when thick, so a sealing process is often needed to achieve corrosion resistance. The process is called "anodising" because the part to be treated forms the anode electrode of an electrical circuit. Anodized aluminium surfaces, for example, are harder than aluminium but have low to moderate wear resistance that can be improved with increasing thickness or by applying suitable sealing substances.  Anodic films are generally much stronger and more adherent than most types of paint and metal plating, making them less likely to crack and peel.

SMB Plating Limited

In 2005 SMB Plating Limited acquired Plym Plating Works Limited of Plymouth and the two businesses were amalgamated to form SMB Plating Limited.

The acquisition of Plym Plating Works gave added production capacity and enriched the blend of expertise and experience across the organisation.  High Quality Plating has now been going on continuously at the Plymouth works since 1972.

This heritage of quality and service does not stop the company from investigating the latest modern techniques and processes to ensure that their customers benefit from the best service at a very competitive price.
