Effects of La3+ on the hydrogen permeation and evolution kinetics in X70 pipeline steel
The inhibitory effect of La3+ on the hydrogen permeation of X70 pipeline steel was investigated via steady-state hydrogen permeation current (i∞) Airliner through electrochemical hydrogen permeation tests.The experimental permeation data were fitted with a constant concentration model and Electrochemical Impedance Spectroscopy (EIS) tests were co
