Characterizing the Evolution of Iron Carbonate in a Demanding CO2 Environment Using a Combined Electrochemical Impedance Spectroscopy and Linear Polarization Resistance Approach

Product Number: 51323-19278-SG

Author: Robert Jacklin, Joshua Owen, Danny Burkle, Richard C. Woollam, Richard Barker

Publication Date: 2023

$20.00

Carbon steel exposed to aqueous CO2 environments can be conducive to the formation of naturally protective corrosion products, namely iron carbonate (FeCO3). Understanding how FeCO3 develops across a range of conditions is a critical step in enabling the optimization of corrosion products as a natural form of corrosion mitigation. To date, most studies investigating FeCO3 development focus on near-neutral pH solutions conducive to fast precipitation while test pressures are generally atmospheric to simplify in situ electrochemical measurements.

Materials selection in the biomedical sector has become a critical area of research, and the care and treatment of patients need to be continuously improved as technology advances. There is a broad range of such applications for metals in the current state of the industry, including dentistry and orthodontics, surgical tools, implants, stents, and bone staples and screws. Each of these applications entails a unique environment within the human body, and as new alloys are developed, it is crucial to understand their degradation behavior and response when exposed to the harsh conditions found throughout biomedical applications.

Corrosion of Additively Manufactured Stainless Steel 304L in Chloride Solution

Product Number: 51324-21159-SG

Author: Leila Saberi; Mehdi Amiri

Publication Date: 2024

$40.00

Although there have been major strides in understanding the influence of additively manufacturing (AM) on mechanical properties such as tensile and fatigue, the understanding of the corrosion performance of AM-produced metals and alloys remains in its infancy. The corrosion performance and mechanical properties of AM metals are significantly influenced by their unique microstructural features that are highly dependent on the build parameters. These features include surface roughness, porosity, grain directionality, residual stresses, oxides, atypical inclusions, and sub-structures, to name a few. Such microstructural/defect features are distinct in comparison with those of cast or wrought alloys and span many orders of magnitude in length scale. Consequently, AM plays a significant role in corrosion performance. In this paper, the corrosion of additively manufactured stainless steel 304L (AM SS304L) in 5% NaCl solution is studied. The purpose of this research is to understand the correlation between microstructural/defect features and corrosion properties. The effects of surface roughness, surface porosity, and build orientation on corrosion and pitting potentials are investigated. All these features show significant impacts on corrosion performance of AM SS304L. Detailed microstructural and elemental analyses are performed to further understand the interrelation between microstructural/defect features and corrosion properties.

Development of a Water Ballast Tank Coating Monitoring System

Product Number: 51323-19320-SG

Author: Anders W. B. Skilbred, Kevin Farinholt, Erik Risberg, Fritz Friedersdorf

Publication Date: 2023

$20.00

Inspection of ballast tanks and enclosures is generally performed using traditional methods such as
visual inspection and non-destructive evaluation (NDE) techniques. However, it is common for these
methods to often be labor intensive and limited by physical restrictions that prohibit access to certain
areas. Further, the evaluation of the coating condition is heavily dependent on the inspector, and the
quality of the data gathered is varying.

Effects of Environmental Exposure on Mechanical and Barrier Properties of an Aircraft Coating System

Product Number: 51324-21200-SG

Publication Date: 2024

$40.00

Laboratory and outdoor exposure testing can be used to provide controlled or well-characterized environments for understanding how environmental factors alter coating system properties that can be used to understand systems employed on aircraft. Accurate determination of the state of the coating system would help eliminate unnecessary paint removal operations and thereby reduce worker exposure to, and costs associated with, hazardous materials handling arising from paint removal and repainting operations. A commercial aircraft coating system was exposed to laboratory environmental stressors and outdoor exposure on an atmospheric exposure rack to mimic in-service environments. Equivalent circuit parameter values of electrochemical impedance spectroscopy (EIS) data were linked to mechanisms affecting the deterioration of the coating system in response to in-service environmental exposures. Laboratory and outdoor fatigue testing of the coating system and primer coating resulted in cracking of the coating layers. These cracks allowed faster ingress of electrolyte, as seen in EIS measurements, which would shorten the lifespan of the coatings. Area scans using a scanning Kelvin probe instrument were consistent with the EIS interpretation of fatigue degrading the coating barrier properties, while scanning electron microscopy (SEM) images showed an increased linear density of pretreatment cracks in the fatigued coating samples.

Fluoroethylene vinyl ether (FEVE) resins were developed to overcome some of the challenges of traditional fluoropolymer resins exhibited in paint coatings. FEVE resins are synthesized from two monomers, fluoroethylene, and vinyl ether. When these monomers undergo radical polymerization, they produce amorphous A-B-type polymers shown below (Figure 1).
