Correlation study on general and accelerated corrosion of the welded structure of aluminum alloy 2219 in N2O4
Abstract
Purpose
This paper aims to present a correlation study on general and accelerated corrosion of the welded structure of aluminum alloy 2219 in N2O4.
Design/methodology/approach
Corrosion experiments of the Tungsten Inert Gas (TIG)-welded aluminum alloy structure were conducted under both mild and accelerated corrosion conditions by changing the water content in N2O4.
Findings
The experimental results indicated that both general and accelerated corrosion processes of the TIG-welded structure of aluminum alloy 2219 in N2O4 followed the linear equation ΔW = A + Bt, and the corrosion products were unchanged regardless of the water content in the N2O4 solution.
Originality/value
The weight loss comparison method is used to identify the structure of the conventional aluminum welding and aluminum welding structure corrosion dinitrogen tetroxide in nitric acid accelerated corrosion relationship.
