Zircotec

Zircotec is a high temperature coating and heat barrier manufacturer, based in Abingdon near Oxford, England. It uses plasma-sprayed ceramic materials to provide thermal and abrasive resistance to components - with a focus on automotive exhaust systems. Its best-known products include coloured thermal barrier coatings and Zircoflex - a flexible ceramic heatshield.

History
Zircotec Plasma-Spray Process

1960-2003: Development at UKAEA

Zircotec began life as part of the United Kingdom Atomic Energy Authority, where its high temperature coatings and heat barrier processes were originally developed for the nuclear industry. It was based at the Atomic Energy Research Establishment near Harwell, Oxfordshire. At the time, this was the main centre for atomic energy research and development in the United Kingdom.[1]

In 1994, Zircotec's thermal barrier coatings were first used in a motorsport application. These coatings were applied to the exhaust systems of Subaru rally cars to lower in-cabin temperatures. After initial success, these high temperature coatings were then used on a variety of other vehicles, including Formula One cars and trucks.

2003-09: Foundation of Zircotec

Zircotec was bought by a venture capital fund in 2003. Subsequently, Zircotec shifted its focus from the nuclear industry, towards general industry and automotive applications. As a result, Zircotec developed Thermohold coatings for high performance automotive and classic car applications. Their main Thermohold coating was called Performance White, a white dual-layer plasma-sprayed ceramic.

In July 2007, Terry Graham was appointed as the new managing director.[2] Later that year, high performance sportscar manufacturer Koenigsegg announced it would be using Zircotec coatings on its CCX supercar.[3] Additionally, in October, Zircotec became involved in the world land speed steam-car record attempt, supplying its coatings for thermal protection of sensitive components - this attempt was successful a year later.[4][5]

In June 2008, Zircotec developed a plasma-sprayed ceramic coating specifically for composite materials. Predominantly aimed at motorsport and high-performance car applications, coated composites could now function at temperatures above their melting points.[6]

In September 2008, Zircotec launched its Performance Colours range. This range is based on Zircotec's Performance White coating, but has an additional coloured finish - offering a more robust and maintainable finish. Zircotec initially released thirteen different colours, with plans to increase this variety over the next few years.

2009-present: Management buyout

Zircotec's directors completed a management buyout early in 2009.[7]

In 2010, the company's headquarters were relocated to the nearby town of Abingdon, Oxfordshire. The move was completed to provide increased production capacity and to accommodate future business growth.[8]

In 2011, Zircotec developed the world's first flexible ceramic heatshield, named Zircoflex.

Performance Range
Chilled Red Performance Colours Coated Exhaust Pipe

Zircotec's Performance Range is based on its Thermohold coating. Each coating consists of a ceramic based material, plasma-sprayed in two layers onto the component. This coating is predominantly used for thermal insulation, thermal protection and its anti-wear properties. When used on an automotive exhaust system, exhaust skin temperature and under-bonnet temperature have been reduced by 33% and 50 °C, respectively.[9]

The range contains fifteen individual coatings - one white coating (Performance White), and fourteen coloured coatings (Performance Colours). The Performance Colours coatings are identical to the Performance White coating, but consist of an additional coloured top layer - offering a more robust and maintainable finish. The Performance White coating is suitable for temperatures of up to 1400 °C, whilst Performance Colours can be used up to 900 °C. The current colours on offer are as follows: Graphite, Solid Black, Metallic Black, Alaskan Blue, Warm Grey, Antique Silver, Sterling Silver, Chilled Red, Yellow Gold, Copper, Aqua Green, Fern Green, Aged Brown and Ultra Blue.

Primary Range

Zircotec's primary range was developed as a lower cost derivative of its Thermohold coatings. Suitable up to 900 °C, it offers less thermal performance to the Performance Range with a 25% reduction in exhaust system temperatures. Currently Zircotec only offers a black finish, but there are plans to make more colours available.

Zircoflex

Zircoflex is a flexible aluminium-backed ceramic heat-shield, claimed to be the first-ever such product. Based on a derivative of Zircotec's Thermohold coating, close-packed ceramic platelets are plasma-sprayed onto an aluminium foil. This allows tight folding of the heat-shield through 180°, whilst still maintaining thermal protection.[10]

Zircoflex is 0.25mm thick and lightweight at 460g/m2. The heat-shield is useful at temperatures up to 500 °C.[11]

Composite Coatings

Zircotec offers a plasma-sprayed ceramic coating specifically for composite materials. Commonly used on CFRP, this coating protects against heat, fire and abrasion.

Ceramic Fabrications

Zircotec manufactures a number of different industrial ceramic components. Some examples are as follows:

  • Susceptor tubes for optical fibre production;
  • Ceramic furnace components, such as ceramic tubes;
  • Ceramic filters;
  • High temperature ceramic crucibles;
  • Ceramic components for electrical and thermal insulation.
