Plasma and PVD lay thin coatings
Physical vapour deposition (PVD) processes allow a wide choice of metals, ceramics, and organic compounds to be applied to metal, ceramic and polymeric substrates.
DLC process coats internal bores and pipes
A diamond-like carbon (DLC) coating process coats internal bores, pipes, cylinders, tubes and pump parts with coating thicknesses of up to 50 micron.
Representing an investment of around GBP 500,000, the second furnace supports the vacuum brazing service that serves aerospace, marine, medical engineering and pharmaceutical processing industries, as well as specialist toolmakers.
The new furnace is linked to a precision automated cleaning line to ensure very high levels of braze integrity, and gives Tecvac additional resources to manage complex brazing tasks.
Already some projects involving more than 20,000 discrete joints in a single sub-assembly have been successfully completed.

Display systems fabrication qualifies to ISO 9001
Leading retail display systems manufacturer has joined the first wave of companies working towards compliance with the new ISO 9001: 2000 quality standard.
"We are seeing increased demand for high quality service in this sector," said WHT director Peter Carpenter.
"We have invested in an additional, larger capacity furnace at Cambridge, together with support facilities at our Bury, Lancashire site.
This will ensure that our customers have a completely reliable, high quality service and guaranteed fast turnaround".
Components can be vacuum brazed using alloys of copper, nickel, gold and silver, to join similar or dissimilar metals and/or ceramics and cermets.
The service covers components using alloy steels, tool steels, titanium alloys, nickel and super alloys and copper, tungsten and molybdenum alloys.
The additional furnace at Cambridge guarantees fully temperature controlled performance down to a vacuum of 10 -5mbar at temperatures above 750 deg C.
All components and sub-assemblies can be annealed or receive other post-brazing treatments on site at Cambridge.
Both vacuum brazing furnaces will accept complex assemblies up to 1500mm by 900mm by 800mm, and provide high surface quality, corrosion-free surface finishes.
This enables Tecvac to offer exceptional brazing integrity and high quality surface finish using high melting point brazes with the most advanced component materials.
Various brazing methods, using paste, wire, shim, or tape, are available to suit production requirements.
Tecvac expects demand for the service to continue increasing.
Typical applications include all types of aerospace and precision medical components, high performance components for Formula 1, and specialist applications such as high vacuum assemblies and heat exchangers.
Tecvac's new service is already accredited to the AS 9100 Quality System, and complements the heat treatment and NADCAP approved hard coating service.
The vacuum brazing service is also available through other Wallwork Group sites in Manchester and Birmingham, with an integrated collection and delivery service covering most areas of the UK.
