- Surface Engineering
Dr Luis Isern Arrom is a Research Fellow in High Temperature Surface Engineering at SEPi currently working on coatings for extreme environments.
Luis graduated from Industrial Engineering and Materials Engineering at the Polytechnic University of Catalunya (UPC) in Barcelona, Spain. His degree in Industrial Engineering covered a wide range of engineering disciplines, from fluid dynamics, transportation and project management, to mechanics, electronics, and materials. His further degree in Materials Engineering gave him a broad understanding of polymers, metals and ceramics. In his degree thesis, Luis worked in the tomographic reconstruction of corrosion attack on Co/WC cemented carbides.
After a brief stay in the automotive industry as analyst of the Metallic Materials Laboratory of SEAT, he started his doctoral studies at Cranfield University in 2014. During his PhD, sponsored by SIFCO ASC, Luis developed metal matrix composite coatings deposited by brush electroplating (selective plating) such as Ni/WC, Ni/PTFE and Ni/Cr3C2. After graduation in 2018, he joined SEPi on his current position.
Dr Luis Isern Arrom is a materials scientist with experience in ceramic, metallic and composite coatings, as well as in cemented carbides and diverse metal alloys. His main interests are the design, development, deposition/manufacturing, characterisation and performance testing of coatings and materials for extreme environments. In particular:
For coating deposition and material manufacturing, his main focus is:
- Electron-Beam Physical Vapour Deposition (EB-PVD).
- Electroplating (including brush plating / selective plating).
- Erosion testing
- Wear testing.
- Thermal cycling.Tomography.
