Armoloy (UK) Ltd is the UK licensee for the Armoloy NTDC (Nodular Thin Dense Chrome ) process.

This process deposits a unique, nodular 99.9% pure Chromium coating that has been approved for use in Aerospace, Oil & Gas, Nuclear and other high technology industries yet is also certified as safe to use for Food, Pharmaceutical and Medical equipment.

Proven in the Valve Industry
Armoloy has been available in the UK for more than 20 years now and, in that time, has successfully tackled thousands of applications that impact, either directly or indirectly, with valves and actuators. Components have included vanes, cylinders, rotors and pistons, sealing rings and bearings.

We have tackled all aspects of industry from miles up in the stratosphere to applications deep down in the ocean depths for the Oil & Gas industry.

The beneficial properties of Armoloy include its hardness in combination with its corrosion resistance in combination with its natural slipperiness. This gives it great resistance to abrasive wear and galling.

One more thing - it doesn’t come off in service. Armoloy will not chip, crack or peel under normal operating conditions. Essentially, this is a dynamic coating that shows its true potential under working conditions.

Over the years, the Oil & Gas, Power, Petrochemical and Valve specifiers have turned to ever more exotic metals and alloys. They are now able to offer certain invaluable properties in their performance. However, against this increasingly narrow range of brilliance must be offset the fact that the majority of them suffer from wear problems and have a natural talent for picking up or “stickability.”

As a result of the properties described above, a thin coating (5 microns) of Armoloy NTDC will either eliminate these problems or make them manageable. This will provide a workable solution on sliding, reciprocating, rotating or threaded surfaces over a wide range of temperatures (-200 to +600 degrees). This thin coating is unlikely to affect most manufacturing tolerances and, in many instances, can be allowed for thus eliminating any further machining and jumping straight to the assembly operation.

Masking, where specified, can be achieved although the very thinness of the coating renders it unnecessary in many applications and the area can be described as “optional” in working drawings. One benefit that is attainable from uncoated, masked off areas is the potential for different coatings on different areas of the component. This is equally applicable to internal as well as external surfaces - long bores and internal threads are not a problem for Armoloy provided that access is available. Line of sight is also not essential.

Armoloy NTDC is an internationally recognised problem solver; we thrive on awkward one offs and specials. Our size capacity covers a wide range of shapes and we can handle up to 5000 Kgs. Our customer base runs through Europe and the Middle East out to the Far East.

Company accreditations include ISO 9001, ISO AS 9100 Rev.C and NADCAP. We operate to a wide spectrum of international specifications as well as a continually increasing list of specifically tailored company specifications.
