Armoloy & the Nuclear Industry
The Armoloy coating, as a problem solver for components in the nuclear industry, has a long history- even longer than the history of Armoloy (UK).
Prior to the establishment of the first European processing license, Armoloy of Illinois were processing a significant volume of nuclear components for internationally recognisable names in the industry. The coating applied then, by that plant, is identical to the coating applied by Armoloy (UK).
Armoloy (UK) Ltd was formed in 1989 and was approved to supply Rolls -Royce Aerospace from its inception. This approval was later extended to the Marine Power division and, from that point, has continued on to numerous major suppliers in the industry. Armoloy is also recognised in the government specification DGS/PS/5250. From a Quality point of view, Armoloy (UK) also holds accreditations for ISO9001, AS9100 Rev.C and NADCAP.
The Armoloy NTDC ( Nodular Thin Dense Chrome ) coating is 99.9% pure Chromium deposited in a unique, crack free, nodular grain structure that bestows upon it enhanced properties of hardness, slipperiness and corrosion resistance. These benefits enable components to slide easier and resist galling on metal to metal contact. Armoloy NTDC also has the rare property that it will slide against itself with no adverse results. In service, the coating will not chip, crack or peel, the bond to the base material is absolute. The coating is also certified as safe for use in Food, Medical & Pharmaceutical applications.
Many of the common applications for components in the Nuclear industry have to work, by design and necessity, in less than ideal situations. The consequences of a failed component can be enormous. In dealing with this, the industry has turned to highly corrosion resistant steels and other exotic alloys. Unfortunately, the specified base metals are very often prone to abrasive wear and galling or "stickability".
Armoloy NTDC coating can significantly reduce wear and pick up on sliding surfaces and threads. This factor can render many major mechanical problems manageable and can also ease problems of assembly and dis-assembly where a single galled bolt can disrupt procedures.
Armoloy NTDC cannot make bad components into good ones. It can, however, significantly reduce the risk of failure and enhance system reliability.
