What is Tribocorrosion Nickel-Aluminium Bronze Alloys?

Tribocorrosion of nickel-aluminium bronze alloys studies the synergistic effects of mechanical wear and electrochemical corrosion during sliding contact in electrolytes.

Researchers map tribocorrosion mechanisms using pin-on-disc tribometers with in-situ electrochemical measurements. Nickel-aluminium bronze (NAB) alloys are tested against alumina under seawater lubrication at varying halide concentrations (Zhang et al., 2018, 29 citations). Marine applications focus on wear prediction in lubricated bearings (Wood, 2017, 205 citations).

Key Challenges

Why It Matters

Tribocorrosion modeling predicts NAB performance in seawater-lubricated marine propellers and bearings, reducing failure rates. Zhang et al. (2018) quantify synergy indices for halide effects on NAB-alumina sliding, informing alloy design. Wood (2017) maps marine wear mechanisms, applied in naval engineering to extend component life. Rivero et al. (2021, 14 citations) link Ti additions to improved corrosion resistance in cast NAB for erosion-prone parts.

Key Research Challenges

Quantifying Wear-Corrosion Synergy

Depolymerization distinguishes mechanical wear from corrosion requires precise synergy indices. Zhang et al. (2018) measure currents during NAB-alumina sliding in halide seawater. Challenge persists in standardizing indices across electrolytes.

Microstructure Optimization

Ti additions alter NAB phases affecting tribological properties (Rivero et al., 2021). Heat treatments at 500°C modify coating porosity and hardness (Morales et al., 2024). Balancing strength and ductility remains difficult.

Seawater Lubrication Effects

Halide concentrations accelerate NAB tribocorrosion failure (Zhang et al., 2018). Gas pressures in thermal spraying influence Cu-Al coating wear (Morales et al., 2019, 13 citations). Replicating marine conditions in labs is inconsistent.
