Thermal spray coatings for molten salt facing structural parts and enabling opportunities for thermochemical cycle electrolysis

open access: yesEngineering Reports, Volume 6, Issue 9, September 2024.
The review is in relation to coating materials that can withstand thermochemical cycle corrosive environments. The overall assessment is that very limited sets of coating‐substrate system are likely to survive for an extended period in the high temperature thermochemical environment. Recommended solution is to use special metals coated with metallic or

High‐Speed Laser Surface Structuring for Thermal Spray Coating Preparation

open access: yesphysica status solidi (a), Volume 221, Issue 15, August 2024.
The article shows the possible use of fast laser structuring as a replacement for the standard process of grit blasting as substrate preparation for spray coating. For this purpose, steel surfaces are machined with continuous wave, nanosecond, and ultrashort pulse lasers and afterward coated with Stellite 6 and tungsten.
