The existing excimer lasers with pulse durations in the nanosecond range and high pulse and average power afford a unique possibility of influencing the surface of materials and developing new, efficient technologies. It is shown in this article that surface treatment with a periodic-pulse UV laser cleans surfaces by removing oxides, reduces roughness, and increases hardness. Different variants of pulsed laser deposition of aluminum and Al2O3 are used to form protective, composite, cermet layers that suppress surface corrosion of EP-823 steel fuel-element cladding in lead in contact with air at 650–720°C.
