Abstract
A noble method for preparing rhenium thin film on a permalloy substrate has been proposed.Main processes of the method include melting pressed rhenium powders on a substrate by a pulsed Nd-YAG laser beam to form around 30 μm thick rhenium films, tightly bound to the substrate. Optimum conditions for the film preparation were examined by correlating both matrix structures and surface chemical purities with the laser irradiation parameters.Although some difficulties are still remaining, the proposed laser heating will be usefull for preparing high temperature melting films on low temperature melting substrate materials.
