Synthesis of fluorocarbon nanofilms on titanium using high-power KrF laser radiation

Abstract

Fluorocarbon (C : F) nanofilms up to 60 nm thick are synthesised on a titanium surface. The films are obtained by annealing thin layers of fluorocarbon oil (FO) (with an area of 0.6 cm2) in air with pulsed (80-ns) KrF laser radiation having a fluence of more than 4 J cm−2. The strength of C : F nanocoatings turns out to be comparable with that of titanium and exceeds several hundred times the corresponding characteristics of Teflon F-4. The high transparency of FO indicates a possibility of using it as a cover liquid when modifying titanium surface using beams of various technological lasers.
