Research Interests

Our research is mainly  to characterize interfacial mechanisms in corrosion science by integrating electrochemistry, materials science and computer simulation with experimental and theoretical tools,  to apply state-of-the-art electrochemical characterization to determine the spatial distribution of current carriers at different interfaces formed in electrochemical systems (corrosion, batteries, and capacitors),   to develop deterministic-stochastic model and experimental framework for coatings and inhibitors selection as a function of environmental corrosive effects.

 

Currently, we are particularly interested in:

  • Multiscale mechanisms at the advanced materials/electrolyte interfaces.
  • Bonding/delamination mechanism at different scales for inhibitor and coating on different substrates.
  • Electrode synthesis and characterization for lithium ion batteries.
  • Characterization of special alloys in corrosive conditions (pressure and temperature).
  • Development of a conceptual framework and theoretical models to characterize the critical performance/damage parameters for advanced materials under flow conditions.
  • Development of mathematical models based on deterministic-stochastic modeling and validation with multi-scale monitoring system for advanced materials in corrosive environments.

Ahmad Ivan Karayan.

1

PhD Research Assistant.

Broad research Interests:

  • Localized Corrosion
  • Transpassivity of CRA’s
  • Stress Corrosion Cracking
  • Sweet Corrosion
  • Cathodic Protection
  • Root cause failure analysis (RCFA)
  • Reliability engineering, and materials selection for oil and gas facilities.

Dissertation Work:

 Development of a novel crevice former for studying crevice corrosion of steel and CRA’s. This novel crevice former is not only easy to fabricate but also gives reproducible results. The immersion and electrochemical test can be performed simultaneously by using this crevice former without any generation of unwanted crevice corrosion outside the crevice of interest. In addition to my dissertation work, I am currently working on the projects in the early detection of stress corrosion cracking of API X65 using EIS and EFM and presently collaborating with industries in the root cause failure analysis (RCFA) projects.

Dongrui Yang.

2

PhD Research Assistant.

My research topic is mostly about corrosion inhibitors and techniques for slowing down the corrosion process of pipeline steel. Electrochemical techniques and data modeling were employed as the main methods for extracting information regarding electrochemical interfacial phenomena. Surface analysis techniques, such as SEM and 3D microscope, were used to characterize the surface morphologies. Inhibition performance of certain chemicals on other metal materials, such as copper and aluminum, are also being tested and studied. My professional goal is to become an expert about corrosion prevention technologies in both academic and industry

Yenny Cubides Gonzalez

Yenny Cubides Gonzalez Modified

Graduate & Research Assistant. PhD Student.

Research Experience:

– Interfacial characterization of Corrosion Resistant Alloys (CRAs) in simulated concrete pore solution in presence of chloride ions.

– Effect of imidazoline based inhibitors on the corrosion of mild steel in presence of saturated carbon dioxide.

Active Research:

– Electrochemical characterization of CNT’s-Zinc Rich Epoxy Primer (ZREP) on Carbon Steel in simulated concrete pore solution in presence of chloride ions.

The aim of this work is to characterize the interface formed by CNT’s-Zinc Rich Epoxy Primer (ZREP) on Carbon Steel in simulated concrete pore solution in presence of chloride ions. The coating performance will be analyzed by using Electrochemical Impedance Spectroscopy measurements and the correlation of electrochemical testing with localized attack will be supported by the results obtained from Infinite Focus Microscopy (IFM). In addition, morphology analysis will be included by Atomic Force Microscope (AFM) and Scanning Electron Microscope (SEM).

Violeta Valencia Goujon

Graduate and Research Assistant – PhD. Student

Current Research Topics – Coatings

  •  Electrochemical Characterization of Zinc Rich Epoxy Primers (ZREP), (ZREP-CNT) in 3%NaCl – CO2 saturated environment with turbulent flow conditions by Electrochemical Impedance Spectroscopy (EIS): Effect of flow conditions and primer composition.

The main objectives of this research are:

To characterize and mechanistically assess the electrolyte/coating and coating/substrate interfaces of a ZREP in the presence and absence of: i) Turbulent Flow, that tailors the feasibility study of these materials as possible candidates for internal coating application in oil and gas pipeline corrosion protection; ii) Carbon Nanoparticles (CNT) that can provide different protection response by the synergistic coupling of CNT with Zn against corrosive species.

•  Electrochemical characterization of different organic and inorganic pretreatments for ferrous substrates.
