Developing a Corrosion and Wear Resistance Grey Cast Iron Through Laser Surface Alloying/Cladding Technique
The mild-to-severe tribo-corrosion as one of the common challenges in today’s high-performance GCI components such as cylinder liners, piston rings, brake discs, which occurs frequently and limits the component performance and reliability. In addition to the significant economic loss, environmental and health issues related to releasing of nano-sized metallic particles the demand for improving the performance of such materials has increased in recent years. Accordingly, the improved surface tribo-corrosion property of GCIs, using surface Laser Surface Alloying and Laser (LSA) and Surface Cladding (LSC), has a significant effect in sustaining the application of these high-performance components in many industrial applications. So that, the generated knowledge in this project would contribute substantially to improving the durability and sustainability of the new generation of high-performance GCI components in many industrial sectors, specifically transportation (such as cylinder liners, brake discs, high-speed train brake discs).
The DELSA project aims at improving the combined effect of wear and corrosion resistance (tribo-corrosion) of Grey Cast Iron (GCI) using developed surface modification techniques.
This project integrates computational thermodynamics, experimental material production, laser surface modifications and characterizations. The research plan engages a diverse range of competences, from alloy design to metal casting, laser coating, material characterization and thermodynamic calculations. This includes the whole value chain of material development, including research institute, alloy designer, suppliers, and end-users.
