Barnacle Electrode Measurement System for Hydrogen in Aircraft Steel.

Abstract

A portable measurement system for determination of the hydrogen concentration in steels has been developed under contract with the Naval Air Development Center (NADC). This system which is based on the electrochemical permeation technique consists of the barnacle cell, so called because of its magnetic attachment to steel surfaces, and the electronic measurement system. Three prototypes of the combined system have been delivered to NADC. This report contains a description of the barnacle cell and the measurement system including all drawings for the cell components and for the electronic circuits. Complete descriptions of the operating procedures are included. Experimental results obtained with the combined system on 4130 steel and cadmium plated 4340 steel obtained from NADC are presented.
