Abstract Hot-dipped aluminum coating was made on the surface of 30CrMo sheet steel by passivation method.Testing samples were prepared after diffusing,quenching and high temperature tempering.The hydrogen diffusion curve of aluminized steel in hydrogen sulfide saturated salt water was measured with hydrogen penetration electrochemical technology,and the diffusion coefficient (D) of hydrogen in the aluminized steel and the temperature (T) dependence on D were obtained.The effects of NaCl and CO2 in the solution on steady hydrogen penetration current were also studied.Mechanical properties of the aluminized steel and its matrix steel were tested,before and after corrosion in hydrogen sulfide saturated salt water.The results showed that the aluminized steel obviously inhibited hydrogen diffusion and had better hydrogen damage resistance than the matrix steel.

Key words: hot dip aluminized steel hydrogen diffusion hydrogen d amage resistance
