Graphic element Inter-metallic quasi-crystal coating from frying pans to aerospace applications
     
 
Cristome, a high-thermal isolating and low-friction coating replaces Teflon as a polymeric substrate in pans. Other applications are envisaged in the automotive and aerospace sectors.
 

Inter-metallic quasi-crystals were first isolated as early as 1984. These special particles combine aluminium and other metals (manganese, lithium) and have unique properties compared to other crystalline materials, including high mechanical strength, high thermal isolation and low friction coefficient.

This project was aimed at improving the performance of inter-metallic quasi-crystals, developing new coating technologies and new commercial applications. The industrial processes for the production of quasi-crystals was optimised and a variety of depositing techniques were investigated.

The first commercially exploitable result is a material which can replace Teflonâ as a polymeric coating substrate in frying pans. Cristomeâ, a product developed by SNMI, an SME manufacturer and prime project partner, offers scratch resistance well beyond that of current polymeric coatings, while its non-adhesive properties meet the most demanding specifications.

Partners say this is only a starting point. The strong commercial base provided by this consumer goods application will allow continued research on more advanced applications now envisaged in the automotive and aerospace sectors. Similar developments are now being sought in Japan, China and the US.
