| OVERVIEW OF THE UNIFICATION OF THE THEORIES FOR LOCALIZED AND GENERAL CORROSION Digby Macdonald1; 1U. OF CALIFORNIA AT BERKELEY, Berkeley, United States; PAPER: 127/Corrosion/Regular (Oral) OL SCHEDULED: 16:20/Wed. 29 Nov. 2023/Boardroom ABSTRACT: The theories for localized corrosion, such s pitting corrosion, stress corrosion cracking, corrosion fatigue, flow-assisted corrosion, and galvanic corrosion, among other mechanisms and general corrosion have tended to develop independently, many on an ad hoc basis. In this paper a unified theory is resented in which all known forms of localized and general corrosion are accommodated under s singly mathematical framework. The physicoelectrochemical factors that lead to the development of one form of attack over anther are identified and are illustrated by reference to specific examples. Knowing these factors allows us to predict the form of attacks (2) that might be expected for any given metal/alloy under any given set of environmental conditions. |
