| Abstract Scope |
Pitting corrosion is one of the most detrimental failure modes for brass components used in the freshwater sector. To increase service life of components, an accurate model of the effect that grain morphology has on pitting nucleation and propagation and the ensuing effect on fatigue life needs to be understood. Baseline pitting location, number density, and size were established using confocal microscopy and scanning electron microscope imaging on components returned from the field. Pre-corroded samples were indexed and then characterized using electron backscattered diffraction. The samples were subsequently loaded using a rotating bending fatigue test to establish a linkage between grain morphology, pitting nucleation, and crack propagation from the formed pits. The crack growth was monitored ex-situ utilizing digital image correlation at regular intervals during the test. Predicting pitting growth and modeling its effect on fatigue life enables improved designs for life and service of brass-based components. |
