This study investigated the hydrogen permeation property of cementite by fabricating bulk cementite sample using the process combining the mechanical ball milling and subsequent pulse current sintering. The bulk cementite sample having a 96 vol% of cementite was successfully fabricated. The prepared bulk cementite showed no signal of hydrogen permeation during the 3.5 day of electrochemical hydrogen permeation test. The morphology of blister formed in the sample indicated that diffusion coefficient of hydrogen in cementite is very small.
