Abstract
The present disclosure relates to a metal material for a container for storing high-purity hydrogen fluoride, and to a manufacturing method therefor. Specifically, the disclosure relates to a metal material for a container for storing high-purity hydrogen fluoride, and a manufacturing method therefor. The metal material includes a graphite layer on the surface of a metal substance, and nickel fluoride films formed in structural defect spaces within the graphite layer, so that corrosion resistance and scratch resistance are improved, and thus high-purity hydrogen fluoride, which is a corrosive gas, can be stored and transferred without being contaminated.
