RAPTOR aims to understand the mechanisms and kinetics underlying the high temperature corrosion of platinum and its alloys, by developing a surface treatment process to decrease the corrosion kinetics by creating surface alloys.

Platinum and its alloys have excellent resistance to abrasion and corrosion in high temperature ranges, which is why they are widely used in industrial processes. In the glass fibre synthesis process, Platinum-Rhodium alloy dies are used to guide the molten glass to be processed into fibre. During the use of the die, a loss of platinum is observed. At high temperatures, the platinum will oxidise to PtO2 which is not stable and will sublimate, causing the loss of material.

RAPTOR aims to develop a solution to limit platinum sublimation by stabilising alloys, using a combination of plasma technologies: PVD and Ion Implantation.

The two main objectives of this project are to study and understand the corrosion process of platinum alloys and to study the kinetics of high-temperature corrosion stability of new platinum alloys synthesised by combining two plasma technologies.

Objectives and missions of Materia Nova :

Within the consortium, Materia nova is committed to develop a surface treatment allowing the creation of Pt-Me alloy by combination of PVD/Ion implantation.
