TL;DR
This paper studies how corrosion affects the fatigue life of a nickel-aluminum bronze used in marine structures, proposing a faster and more reliable testing method.
Contribution
A novel accelerated corrosion testing method and numerical simulation for predicting fatigue life of ZCuAl8Mn13Fe3Ni2 bronze under marine conditions.
Findings
An accelerated corrosion solution (NaCl, H3PO4 buffer, H2O2, and HCl) effectively simulates marine corrosion damage.
A numerical simulation predicted fatigue life with an average error of 13.82%.
S–N curves for different corrosion cycles were established to evaluate fatigue performance.
Abstract
Corrosion fatigue damage significantly affects the long-term service of marine platforms such as propellers. Fatigue testing of pre-corrosion specimens is essential for understanding damage mechanisms and accurately predicting fatigue life. However, traditional seawater-based tests are time-consuming and yield inconsistent results, making them unsuitable for rapid evaluation of newly developed equipment. This study proposes an accelerated corrosion testing method for ZCuAl8Mn13Fe3Ni2 nickel–aluminum bronze, simulating the marine full immersion zone by increasing temperature, adding H2O2, reducing the solution pH, and preparing the special solution. Coupled with the fatigue test of pre-corrosion specimens, the corrosion damage characteristics and their influence on fatigue performance were analyzed. A numerical simulation method was developed to predict the fatigue life of pre-corrosion…
