Stringent aerospace standard for PVD coating secured
Keywords: Coatings technology, Aerospace engineering
Ultra hard coating and heat treatment business Tecvac Ltd, Cambridge, UK, has been awarded NADCAP accreditation. NADCAP, a high level quality standard introduced by prime aerospace manufacturers, including Boeing, Rolls Royce, Airbus and United Technologies, applies to Tecvac's ultra hard wear and erosion- resistant coatings.
“Tecvac is believed to be the first business in Europe to achieve this standard for specialist aerospace PVD coating processes”, said John Rushforth, Operations Director at Tecvac.
“As part of the accreditation process Tecvac carried out a complete overhaul of all quality and production systems at Cambridge. In addition, the company has just completed the first phase of new investment in new PVD and PACVD processes, valued at more than €1 million, to expand facilities to meet the needs of the aerospace, biomedical and high end automotive engineering businesses”, commented Peter.
Carpenter, a director of Tec vac's parent company Wall work Heat Treatment Ltd.
“While the process of accreditation to this new standard is, as it should be, very rigorous”, continued John Rushforth, “our electron beam evaporation technique used for our PVD coatings produces a highly consistent, defect-free and very smooth coating. This facilitated much of our validation work. This accreditation covers all the flying parts currently coated at Tecvac, including wear-resistant coatings for both titanium and steel aerospace bearings and erosion- resistant coatings to increase the life of gas turbine blades. Tecvac already coats flying parts for several of the prime aerospace suppliers throughout the world, and is constantly finding new applications for the latest ultra hard coatings”.
