Tecvac provides complete vacuum processing solutions.
The  engineering and research team advises on product application, designs complete processes for all types of vacuum coating, and  builds vacuum processing plant for universities, research institutions and businesses worldwide. Tecvac has supplied more than 40 advanced PVD and plasma processing  machines used for advanced  medical research projects.

These machines extend from commercial polymer film coating units, to specialist processors for pharmaceutical  businesses, and complex research machines with multiple electron beam configurations  that allow complex PVD coatings to be developed with multiple metallic, metalloid and ceramic components combined in flexible formulations.

Tevcac's systems management processes  can provide automatic, verifiable logging and tracking of every aspect of treatment, including designated operator interaction, if required. Systems track process parameters and operator actions on a batch by batch basis so ensuring full traceability, and meet cGMP standards.

Substantial research facility
Tecvac maintains a substantial  application research team that provides technical assistance to customers, maintains close links with leading research institutions, and participates in UK and European collaborative programmes  with project partners  in UK, Germany, Italy, Denmark, France, Holland, Spain, Portugal, Romania, Russia, USA, Czechoslovakia & Brazil.

Collaborative research programmes
These programmes have  included:
Brite (EU) RI.1B.0151C(H)
Duplex coatings and plasma nitride on Titanium alloys.

Reduced wear & infection
A new coating developed by Tecvac including silver and chromium nitride has the potential to reduce both wear and joint infection in total hip replacement therapy.
See poster from Queen Mary College, University of London
Project BERTI; (Biomedical implant with Exceptional Resistance to Tribo-bio-corrosion and with Inherent antimicrobial properties) is expected to lead to new designs of  knee and hip implants and  substantially reduce the number of costly revision surgeries for hip and knee replacement patients. Partners in the project include Corin Plc, Tecvac Ltd, Imperial College, University of London, Charing Cross Hospitals, Queen Mary College, University of London and the University of Sheffield.

Page update 21 January 2013
SMART-HIP, a research project led by Cambridge coating specialist Tecvac Ltd and leading UK hip prosthesis manufacturer, Corin Ltd, has demonstrated the potential of new enhanced wear resistant coatings to increase implant longevity in Metal-on-Metal (MoM) hip prostheses and future potential applications to trunnions and tapers to prevent fretting and corrosion.

New PVD silver bearing coatings were developed which may protect against post-operative infection, and also provide a barrier to minimise metal ion release. Optimised coatings reduced the release of one important metal ion (Cobalt), implicated in chronic tissue inflammation, by 99%.
