What is Corrosion Mechanisms Nickel-Aluminium Bronze?

Corrosion mechanisms in nickel-aluminium bronze involve selective phase attack, dezincification-like processes, and passivity breakdown primarily in marine environments.

Nickel-aluminium bronze (NAB) alloys exhibit corrosion through selective dissolution of phases like beta and kappa in seawater (Wharton et al., 2005, 319 citations). Researchers use electrochemical impedance spectroscopy and surface analysis to study these mechanisms. Over 20 papers document erosion-corrosion synergy and microstructural influences on NAB durability.

Key Challenges

Why It Matters

Understanding NAB corrosion extends service life of marine propellers and valves, reducing maintenance costs in naval applications. Wharton et al. (2005) showed selective phase attack dominates in seawater, guiding alloy optimization for offshore structures. Barik et al. (2005, 136 citations) quantified erosion-corrosion performance, informing thermal spray coatings for pump impellers. Wood (2017, 205 citations) linked tribocorrosion to propeller wear, enabling predictive maintenance models.

Key Research Challenges

Selective Phase Attack

Beta and kappa phases in NAB undergo preferential dissolution in seawater, accelerating overall corrosion rates. Wharton et al. (2005, 319 citations) identified this via impedance spectroscopy. Mitigating phase-specific attack requires microstructure control during casting.

Erosion-Corrosion Synergy

Mechanical erosion removes protective films, amplifying corrosion in flowing seawater. Barik et al. (2005, 136 citations) measured synergy in cast NAB using wear tests. Quantifying interaction terms remains difficult for predictive modeling.

Passivity Breakdown

Chloride-induced breakdown of passive oxide layers exposes alloy to pitting in marine settings. Basumatary and Wood (2017, 57 citations) studied this in NaCl solutions via electrochemical methods. Stabilizing passivity under hydrodynamic stress poses ongoing challenges.
