Development of “3D print-thermal spray” systems for applications with dynamic and impact loading - DePriSS

Project summary

Additive technologies have potential to produce light and complex-shaped components. However, required service life and reliability under different load modes has to be ensured. Cyclic and dynamic loading can be considered critical. Components surface needs to be protected against wear and corrosion. For various reasons fatigue strength and service life may be reduced. Main objective is the development of 3D print-thermal spray systems resistant against wear and corrosion. Optimization of coatings composition and process parameters will be done. Methodologies for evaluating the response to cyclic and dynamic loads of 3D printed components, coatings themselves and their combinations will be developed and validated. Such combination enables to exploit advantages of 3D printing with benefits provided by thermal spraying. The results will have an impact on extension of both additive technologies into wider range of application, including power, aerospace, automotive, civil engineering etc.
