Abstract
The entry rates of hydrogen into a steel surface were measured under several cathodic potentials and sea water temperatures. This article describes the construction of the hydrogen measurement and discusses the results and their implications. Hydrogen is produced by the cathodic protection of steel in sea water and too great a rate of entry can cause hydrogen embrittlement and be detrimental to the fatigue properties of the steel.
