Tartaric Suphuric Anodising (TSA)

At Acorn Surface Technology, we continually review new and up and coming technologies, with a view to supporting our customers current and future needs.

Within our Industrial Services group, SGI-France, have established a tartaric sulphuric anodising (TSA) facility, which is a REACh compliant chromic anodizing replacement.  This process is now in production for aerospace applications at the Villers-CotterĂȘts facility

TSA is planned for implementation at Acorn Surface Technology for operations from early 2018.

By modifying the processing conditions a wide range of coating properties and charactersitics can be achieved, making anodising an ideal surface engineering technique for a wide range of applications.
Ion Vapour Deposition, is a physical Vacuum deposition process which is used to apply a pure Aluminium coating to various substrates, to improve the resistance to atmospheric and bi-metallic corrosion. 
Incorporating different processes on one component can extend the possible applications and optimise the performance of any item. Specialised masking and treatment methods can be used to achieve the best combination of coatings including anodising, vacuum treatments and wet paint systems.
