£500,000 extension for Tecvac

£500,000 extension for Tecvac Tecvac Ltd has extended production space at its Swavesey, near Cambridge, site by 44 per cent, to provide new capacity for aerospace sector work, PVD/CVD research, machine building, and vacuum brazing.

The new facilities, representing an investment of more than £500,000, include component cleaning lines, vacuum brazing, sub-assembly, and a 400sq. ft. controlled environment area to support PVD/CVD processing, sub- assembly work, and multi-layer coatings for flying parts and aerospace engine components.

These coatings, which include a variety of physical vapour deposition (PVD) and chemical vapour deposition (CVD) coatings, cover many different titanium-based formulations, as well as diamond like carbons (DLC), and the deposition of pure metallic thin films.

Applications of Tecvac's thin film technology include highly stressed turbine blades, engine bearings operating at speeds of up to 20,000rpm, and heavily loaded undercarriage bearings for the latest long haul, high capacity airliners. Other aerospace applications include moving surfaces within flying control and trim actuators, and sacrificial thin film surfaces within emergency and main power systems.

Tecvac's thin film coatings also include Nitron O, a coating specially designed for titanium alloys, which includes a Nitrided diffusion zone beneath a PVD surface coating.

“As the requirements of quality within NADCAP and other aerospace approvals become even more stringent,” says Tecvac director Peter Carpenter, “the controlled assembly and inspection function is becoming a critical part of our service for the aerospace sector.

Other support facilities in the new extension include a fully equipped, robot operated ultrasonic cleaning line, including optional pre-wash and inert gas drying facilities that are integral with the controlled environment area to ensure that no contamination occurs between cleaning and coating.
