Research Abstract

A micro permeation cell for studying hydrogen absorption behavior in a small area on metals was developed. The preferential sites of hydrogen absorption of carbon steel surfaces were found to be MnS inclusions in near-neutral environments. It was demonstrated that the hydrogen permeation currents were extremely increased by the dissolution of MnS inclusions. HS- ions released from the sulfide dissolution promote the hydrogen absorption reaction on steel surfaces. Ti(C,N) inclusions do not dissolve and do not promote the hydrogen absorption in near-neutral environments.
