MoveOn
The IOT combines novel, applied material concepts with the design of coating processes using thermal spray, buildup welding, brazing and PVD technologies. Thermal spraying can be used to apply a wide variety of corrosion and wear protection coatings to a base material. Ceramic matrix composites (CMCs) such as SiC fiber reinforced SiC composites are used in modern earoplane engines to increase efficiency. Components made of CMCs are protected against water vapor-induced corrosion at high temperatures with a thermally sprayed EBC coating system
Task
Within the scope of the work novel Si-based bond coats with improved properties will be developed for advanced EBC coating systems. The lifetime of EBCs will be increased via Si3N4- as well as SiC-reinforcement. The novel Si bond coats will be produced with Si/SiC as well as Si/S3N4 spray powders by atmospheric plasma spraying and high velocity flame spraying, respectively. Subsequently, the structure, phase composition, mechanical and thermo-physical properties as well as the oxidation behavior of the coatings are investigated.
Requirements
We are looking for students in the field of mechanical engineering, materials science or materials engineering. With an interest in coating processes, including thermal spraying and adapted material selection. You should enjoy independent and practice-oriented work.
