CONTENTS Determination of the active substances in the Aberdeen inhibitor Properties of DHQ and formaldehyde Independent roles of DHQ and formaldehyde in inhibition Importance of small molecular size of formalde hyde in its activity in the presence of DHQ Formaldehyde does not neutralize the embrittle ment accelerating properties of S The comparison of several substances similar to DHQ-like properties Theory Basic related studies Testing of the hypothesis that substances which absorb atomic H are good embrittlement inhibitors Moore-Fatique vs diffusion potential tests Relationship between electronic structure and corrosion inhibition properties in ionic radicals containing group 5 and 6 elements Hypothesis tested that S accelerates corrosion by forming a complex with ferrous ion Reversible electrode potentials for Fe Procedures Chemical and metallurgical analyses of specimens.
