Improving Problem Components

No machine or implement design is ever perfect. As much as we’d like to think that no improvement can be made, there is always some area that could be bettered.

This shortcoming might involve a limitation regarding, usability, component life, serviceability and so forth. Many of these restrictions are accepted because of the nature of the materials used to construct a specific component or assembly.

At Armoloy we have learned to work with our customers in an ongoing effort to minimise these limitations and enhance the properties of the materials in question.

Two excellent examples that have yielded many successful applications have involved Nickel based alloys and the 300 series of Stainless steels. Whilst both of these materials offer a wide number of individual formulations, the majority of each, the majority of each, although offering superb corrosion resistance, also share a significant drawback in that they are prone to pick up or galling when in service.

Armoloy has long recognised this problem and has had and continues to have major successes in eliminating or significantly reducing this problem thus improving the performance / life of the component. This achieved by applying, directly to the component surface, a microscopically thin layer of the unique Armoloy coating. No bonding interlayer is required and the minimal thickness of 3-5 microns means that the majority of drawing tolerances will not require amending.

The Armoloy coating as a hardness well in excess of 72Rc and has the novel property that it will happily slide against itself without negative consequences. The application of the coating is genuinely a cold process (less than 70°C) thus eliminating any risk of distortion of the substrate. The bond strength is absolute, meaning that the coating will not flake, chip or peel under normal working conditions.

Typical applications for Armoloy include bores, ODs, Sliding and mating surfaces, gear teeth, feed screws, threads (male and female) amongst others. Armoloy UK can handle components from a few grams up to a maximum of 5000kgs with sizes ranging up to 4500mm in length. Industries served include Aerospace, Nuclear, Oil & Gas, Food Processing, Packaging, Pharmaceutical and Medical. The Armoloy NTDC coating is chemically neutral and completely non-toxic. It has passed numerous biocompatibility and toxicological tests. Armoloy is also fully compliant with the requirements of the REACH Legislation.

The quality of our coating and its application are of paramount importance to us and we continue to operate in accordance with our AS9100C and BE EN ISO 9001:2008 accreditations. We also currently hold merit status for our NADCAP accreditation. We can, if required, comply with a variety of internationally recognised specifications or work to your own specifically written directions where relevant.
