Anodising is a complex process that electrically converts the aluminium surface and sub-surface to a columnar structure of aluminium oxide. The porous structure can then be sealed with various chemistries to add additional properties.

Anodised coatings are typically sealed to improve their corrosion protection that is filling or hydrating the pores in the columns, using either hot water, chromates or acetates. The columns can also be filled with an ultra-fine aqueous dispersion of PTFE, improving the friction and wear properties of the coating (Apticote 350), as well as its corrosion properties.

The most dense coatings are produced from pure aluminium alloys. The presence of alloying elements like copper and silicon produces macro-porosity in the coating, reducing its corrosion protection properties.

Poeton offer a wide variety of anodising techniques, with each being tailored to provide different properties.


Over the last 120 years, Poeton Industries has been at the forefront of plating technology and development. Having provided plating services to a wide range of industries covering a huge array of applications. In each instance, the plating technique has been carried out with exacting standards. Poeton’s R&D laboratories have developed many new processing and jigging techniques over the years and were pioneers in precision chrome plating.

Plating is the process of a metal being deposited onto the surface of a conductive material and is achieved through either electroplating or auto-catalytic plating. Poeton can offer plating treatments onto a range of substrates to enhance the properties including corrosion and wear resistance.

Thermal Sprays

Poeton offer state of the art thermal spraying equipment, plasma spraying , encompassing wire, electric arc, and high-energy processes, supported by sophisticated PC-controlled five axis robotic manipulation.

Our Sulzer Metco MultiCoat® can simultaneously control up to four thermal spray processes from a single console. With advanced processing, trending and reporting features, MultiCoat® offers superb performance and value for all types of spray operations, from R&D to high-volume production.

As with all surface treatments, the technical competence of the process engineers and operators is paramount to achieving a consistently high standard of coating. Poeton therefore have invested heavily in the training and development of our thermal spray experts.


Non-destructive testing (NDT) is a wide range of inspection processes that test for material flaws and defects without damaging or altering the parts.

Poeton’s NDT services allows for parts to be evaluated to ensure integrity and reliability as well as saving time and costs compared to other inspection methods.

Conversion Coating

Conversion coatings are primarily used to reduce the corrosion effect on aluminium. They also form an ideal surface for paints to bond to. They can therefore be used in the painted or un-painted condition.

Conversion coatings produce a surface film through a chemical reaction with the substrate, which essentially converts the surface. If coatings and paint systems are applied to an aluminium surface with no prior surface conversion, the paint adhesion will be poor and paint may flake off.

Typical conversion coatings like Alocrom or Alodine contain Hexavalent chrome, which means they continue to protect the substrate material even if the paint layer is breached. However, under the new REACH regulations the use of hexavalent conversion coatings is coming to an end. Therefore, Poeton has invested a huge amount of R&D resource over the last 7 years evaluating and perfecting the application methods of the Alocrom alternatives, such as: Surtec 650, Iridite NCP, Socomore TCS PACS and Lanthane.

Dry Film Lubricants

Dry film lubricant solutions are comprised of very small particles of lubricating agents mixed with a binding resin. The coating is then cured to bond the surface to the substrate.

Poeton’s dry film lubricant treatments are used to reduce wear, galling and heat generation in a range of industrial applications and are commonly used in applications where liquid lubricants would be unsuitable.


With 10 paint spray booths across 3 sites, a variety of pre-treatment and masking techniques and dedicated curing ovens, Poeton Industries can provide a comprehensive painting services. Poeton offers a wide range of paint systems to various defence standards, such as DEF-STAN, MIL-SPEC, as well as a multitude of aerospace approvals, such as Airbus, SAFRAN, Triumph and Collins Aerospace.

Poeton pride themselves on the quality of their paint finish, which can be attributed to the first-class equipment and extensive training. All our paint sprayers are fully trained to exacting standards, allowing us to paint the most complex of geometries.

We stock a wide range of paint systems, which can be applied to a variety of substrate materials. Our Technical Sales and R&D teams are on hand to assist in paint recommendations and specification interpretation.

Value added service

The nature of the Surface Treatment Industry means we typically carry out the last operations in the full manufacturing process prior to delivery to the final customer’s assembly line. However, there are times when minor assembly, bonding or kitting operations are carried out in between the processes being finished at Poeton and parts reaching the final destination. To further support our key partners, Poeton also offer a minor assembly, bonding, and kitting service. As part of our expansion into 2 new buildings in Gloucester we have a dedicated area for carrying out minor assembly operations such as heli coil fitting, bush insertion, component assembly and bonding.

Subcontract service

As part of our commitment to offer the complete service to our partners, Poeton Industries also provide a sub-contract service. In addition to our current in house process capabilities we also sub-contract non-core processes such as: Shot Peening, Heat treatment, Grinding, Machining, Honing and polishing. Poeton Industries will manage all aspects of this process as part of the full package of work, allowing a ‘single purchase order’ scenario. If there are further services that are required outside of these standards, we are happy to review them. To find out more contact us here
