## Description

- description: Local hydrogen entry under a NaCl droplet on an Fe sheet was analyzed
    employing a hydrogenochromic sensor and electrochemical hydrogen permeation tests.
    Large crystallographic pits formed in the initial stage barely promoted hydrogen
    entry, because the pits initiated in weak-acid and the initiation potential is
    higher than the potential of hydrogen evolution reaction. Hydrogen entry was accelerated
    by the acidification under an island-like rust layer. The rust layer became thick
    in the outer regions   due to the alkalization around the rust-formed area. The
    hydrogen entry was prominent under the thick rust layer in drying process since
    it contains NaCl solution.
