Corrosion Control Science and Technology

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 seawater 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

  • 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

  • Establish foundational understanding of the composition, microstructure, electrochemical, and mechanical behavior of compositionally complex alloys (CCAs) made of commodity elements with optimized corrosion properties
  • Explore innovative coating systems with unique functionalities that are capable of responding to environmental stresses
  • 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, as they relate to corrosion properties of compositionally complex alloys (CCAs)
  • Modify the chemistry of feed stock materials to enhance corrosion resistance of AMAs
  • Study microstructural characteristics that affect resistance of AMAs to localized corrosion, especially pitting and crevice corrosion, hydrogen embrittlement and stress corrosion cracking
  • 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 combined effects of compositional complexity and corrosion on crack propagation in CCAs
  • Understand factors that control the effects of additively manufactured alloy (AMA) defects , on corrosion behavior
  • Understand the effect of non-equilibrium segregation of liquid phases during processing of AMAs on resultant local chemistry, microstructure, compositional heterogeneities and surface structure
