Soluble Salt Opinions?

May 17, 2017
Elzly Technology Corporation is conducting a survey of coating inspectors on the detection and remediation of soluble salts. We invite all coating inspectors to participate in the survey. The survey should take most users 10-15 minutes to complete (dependent on the extent of experience with salt detection and remediation). The survey can be accessed at the following link:

Corrosion Protection by Powder Coatings on Atmospherically Exposed Steel

Recent regulations concerning volatile organic compounds (VOCs) and hazardous heavy metals have had an impact on the construction and maintenance practices of transportation authorities. Low VOC coatings have been implemented as a means of complying with recent regulations. Powder coatings are a 100 percent solids material which are heat-cured, thu...

Recent regulations concerning volatile organic compounds (VOCs) and hazardous heavy metals have had an impact on the construction and maintenance practices of transportation authorities. Low VOC coatings have been implemented as a means of complying with recent regulations. Powder coatings are a 100 percent solids material which are heat-cured, thus they have near-zero VOC emissions during application. Federal Highway Administration project DTFH61-91-C-OOO19, "Corrosion Control of Highway Structural Components by the Application of Powder Coatings", was conducted to evaluate various powder coatings designed to protect atmospherically-exposed steel and reinforcing steel from corrosion. The test program included an evaluation of nineteen powder coating systems in a natural exposure test and three accelerated tests. Six of the powder coatings were also evaluated on concrete reinforcing steel cast in a concrete beam. The beam was exposed in a harsh marine environment with a static load sufficient to induce cracking. This paper presents the results of atmospheric exposure testing; a comprehensive report on the project will be published by the Federal Highway Administration.

Title
Current Demand as a Result of Coating Void to Intact Coating Surface Area Ratio
Abstract
Previous research has suggested that a coated steel substrate can be cathodic to boldly exposed steel in seawater. As a result logic would suggest that the corrosion rate at defects in the coating would be a function of the coating to holiday surface area ratio. To examine this hypothesis four (4) surface area ratios were tested in natural seawater...

Previous research has suggested that a coated steel substrate can be cathodic to boldly exposed steel in seawater. As a result logic would suggest that the corrosion rate at defects in the coating would be a function of the coating to holiday surface area ratio. To examine this hypothesis four (4) surface area ratios were tested in natural seawater. These ratios are 3:1, 10:1, 136:1 and 1176:1 (coated to exposed steel). Coated panels were painted with a ML-P-24441 epoxy barrier coating and electrically coupled to exposed steel. During testing the current between mated and uncoated samples was monitored along with the potential between the couple and a saturated calomel reference electrode (SCE). Testing has been conducted for over one year, with each area ratio showing interesting trends. This paper discusses the current flow of each area ratio, and how it relates to the corrosion rate of exposed steel. Whether the corrosion is anodically or cathodically controlled, and to what extent, are evaluated. Finally, "real-world" applications of this type of analysis will be discussed.

DoD and service leadership generally acknowledge the high cost of corrosion control for weapon systems and infrastructure. As a result, they promulgate policy to evaluate corrosion in system design and seek methods to reduce sustainment costs. Yet design practices still face a significant hurdle of defining critical corrosion phenomena and relating such phenomena to system capabilities. While commonly overlooked, the word ?corrosion? covers a wide range of conditions from aesthetic deterioration to acute structural failure. Mitigation methods for each are widely different as are the impacts on system capabilities. The lack of proper definition of corrosion results in a wide variety of corrosion control designs. Some designs are likely inadequate and not all aspects of corrosion are covered. The subject paper suggests a framework for corrosion definitions allowing for better-optimized and cost-effective designs.

The Literature Review and Field Studies portion of this investigation were completed by August 1995. Both revealed myriad factors affecting culvert durability. The literature review considered more than 140 research papers on or relating to the topic of culvert durability. Of these papers, roughly 60 were considered further and are included in an annotated bibliography. Many references are made in the report to past research efforts and conclusions from these papers. Summaries of these conclusions include laboratory and field research on various culvert materials and durability methods. These summaries are included to help in both the selection of pipe material and in the use of durability prediction methods. Those papers presenting field data similar to that used in the present study (including pit depth, age and original thickness) were consolidated into a database of information on more than 240 galvanized culverts. The focus of field studies conducted during this investigation centered on the performance of Aluminized Type 2 culverts. Of the 32 culverts inspected during this investigation, 21 culverts were part of a previous Federal Highway Administration (FHWA) study. These culverts were located in Alabama and Oregon. Eight culverts at five sites in Maine were added with the expansion of these fieldstudies. In situ field measurements of pH and resistivity were taken at each culvert. The abrasive situation at each culvert was characterized, including slope, flow velocity and abrasive material. Each culvert was photo-documented and many were videotaped for future reference. Coupon samples were taken at each location for pit-depth analysis. Soil samples were removed for laboratory resistivity measurements. Conclusions from past research, the database and present field studies have been used to evaluate current durability prediction methods. Advantages and disadvantages of various culvert materials are discussed, with correlations drawn from the literature review and field studies.
