Corrosion Control Technologies

The objective of this Office of Naval Research program is to develop corrosion-resistant alloys and coatings, corrosion-control and -prevention technologies, and processes to mitigate corrosion and its effects under sea water and marine environments.

The primary focus is to explore science-based understanding of corrosion damage evolution mechanisms, corrosion-informed materials concepts, and surface protection and modification sciences.

Research Concentration Areas

Specific areas of interest include:

  • Corrosion-resistant materials
  • Environmentally benign, advanced marine coatings
  • Fundamental understanding of corrosion mechanisms and processes
  • Multi-scale, corrosion phenomena models to predict corrosion behavior that enable corrosion-informed materials selection and design
  • Surface-modification technologies

Research Challenges and Opportunities

  • Understand factors that control the effects of additively manufactured alloy (AMA) defects, including the role of porosity connectedness, defect density, impurity segregation, and solidification structure and anisotropy on corrosion behavior
  • Quantify non-equilibrium segregation of liquid phases, local chemistry and the effect of present carbide, oxide and sulphide during processing of AMAs
  • Study microstructural characteristics that enhance resistance of AMAs to localized corrosion, especially pitting and crevice corrosion, hydrogen embrittlement and stress corrosion cracking
  • Explore the process-microstructure-chemical/electrochemical properties linkages leading to a fundamental understanding of corrosion mechanism in AMAs
  • Explore the relation of processing to microstructure, and microstructure and compositional evolution, the thermodynamic and kinetic properties of compositionally complex crystalline phases, grain and phase boundaries, and surfaces, especially as they relate to corrosion properties of compositionally complex alloys (CCAs)
  • Study the energetics and kinetics of electrochemical reactions of CCAs at multiple length scales, and the characterization of these materials in corrosive environments
  • Study the roles of compositional and structural complexity in reactivity, passivation and repassivation, the development and evolution of cracks, and the synergistic effects of compositional complexity and corrosion on crack propagation in CCAs
