Preparation of Superhydrophobic Coatings on Zinc as Effective Corrosion Barriers
ACS Applied Materials & Interfaces, 2009Stable superhydrophobic films with a contact angle of 151 +/- 2 degrees were prepared on zinc substrates by a simple immersion technique into a methanol solution of hydrolyzed 1H,1H,2H,2H-perfluorooctyltrichlorosilane [CF3(CF2)5(CH2)2SiCl3, PFTS] for 5 days at room temperature followed by a short annealing at 130 degrees C in air for 1 h.

Fluoropolymer barriers to stress corrosion in optical fibers
Journal of Materials Research, 1987Some recent studies on fluoropolymers that exhibit substantially increased barrier properties against the migration of moisture when compared to conventional fiber coating materials, and as a result may offer unique advantages for use in optical fiber applications, are reported.

MASTIC “BARRIER” TO GALVANIC CORROSION: Corrosion Prevention on Ships of Different Metals
Anti-Corrosion Methods and Materials, 1957Electro‐chemical action is becoming an increasingly serious cause of corrosion, particularly with new metals such as aluminium coming into wider use for shipbuilding. In modern sea‐going ships with large parts of their superstructure built of aluminium, electrochemical corrosion can be a major problem.

Characterization of corrosion products in the permeable reactive barriers
Environmental Geology, 2000The impact of geochemical processes and microbial activity has been a major concern for the long-term performance of reactive iron barriers because corrosion products and precipitates during the water treatment with reactive materials will decrease the reactivity and permeability of the iron bed.

Corrosion Barrier Deterioration and Detection in FRP Structures
CORROSION 2000, 2000Abstract Exposing vinyl ester FRP corrosion barriers to five chemical environments illustrated distinctly different degradation mechanisms. Electrical resistance measurements were successful in detecting the extent of damage in each of the environments.

Graded coatings for thermal, wear and corrosion barriers
Materials Science and Engineering: A, 2003Abstract The present paper summarizes the main results generated in a German National Science Foundation (DFG) program on projects concerned with functionally graded materials applied to optimize the thermal, wear and corrosion properties of metallic and ceramic materials.

Multi-Phase Corrosion of Engineered Barrier Materials
CORROSION 2004, 2004Abstract When moist residual solids resulting from evaporation of simulated concentrated unsaturated zone (UZ) pore water were heated, corrosive gases produced by the hydrolysis of crystallized magnesium salts were released. Gases detected included Cl2, NO and NO2, along with the acid gases HNO3 and HCl.

The evaluation of corrosion processes for engineered barrier systems
JOM, 2005The U.S. Nuclear Regulatory Commission (NRC) established a corrosion program to evaluate the predicted performance of the U.S. Department of Energy’s proposed engineered barrier system for the potential high-level waste geologic repository at Yucca Mountain, Nevada.

Hexagonal Boron Nitride: The Thinnest Insulating Barrier to Microbial Corrosion
ACS Nano, 2018We report the use of a single layer of two-dimensional hexagonal boron nitride (SL-hBN) as the thinnest insulating barrier to microbial corrosion induced by the sulfate-reducing bacteria Desulfovibrio alaskensis G20. We used electrochemical methods to assess the corrosion resistance of SL-hBN on copper against the effects of both the planktonic and ...
