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:

Title
Emphasizing Engineering Design Parameters in Corrosion Control Systems
Abstract
The paper discusses the need to assign quantifiable and measurable criteria concerning corrosion engineering requirements within system design in order to best control maintenance costs and ensure system reliability. Using examples in both commercial and military systems, the paper will show that non-objective engineering targets can lead to solu...

The paper discusses the need to assign quantifiable and measurable criteria concerning corrosion engineering requirements within system design in order to best control maintenance costs and ensure system reliability. Using examples in both commercial and military systems, the paper will show that non-objective engineering targets can lead to solutions that are either expensive or non-applicable to the potential problems. The topic will also illustrate the need for better communication concerning corrosion engineering requirements between the RDT&E community, design engineers, and procurement officials to provide for the best corrosion control system.

Title
Erosion Control of Nickel Aluminum Bronze in Flowing Seawater
Abstract
Erosion corrosion is an important consideration in the design of systems in which materials are exposed to nonuniform fluid flow. There have been inconsistent experiences with the relationship of seawater flow rates and wastage of copper alloys.

Erosion corrosion is an important consideration in the design of systems in which materials are exposed to nonuniform fluid flow. There have been inconsistent experiences with the relationship of seawater flow rates and wastage of copper alloys. This study specifically addresses corrosion of NiAl-bronze (Alloy C958) in flowing seawater at velocities of 25, 50, and 100 feet per second (fps). The testing described in this paper was conducted to determine the amount of weight loss, the characteristic pitting and changes in surface roughness that will occur when NiAl-brcnze (Alloy C9S8) is exposed to different seawater velocities under freely corroding and cathodically protected conditions. Under freely corroding conditions, corrosion increased with increasing flow rates. Nonuniform corrosion occurred at the lowest flow rate (25 fps). The higher flow rates showed uniform corrosion evidenced by a smooth, polished appearance after exposure. Cathodic protection to -0.60 Volt versus silver-silver chloride essentially stopped corrosion of the coupons exposed to low and high flow rates (25 and 100 fps). The cathodically protected coupon exposed to 50 fps flowing seawater had significant nonuniform corrosion. The results of this study suggested that the turbulence intensity, in addition to bulk flow velocity, affected corrosion rates. The results showed significant pitting occurred under highly turbulent flow conditions. Further investigation is required to define the relationship between turbulence intensity and corrosion both under freely corroding conditions and with cathodic protection.

Title
Evaluation of Permanent Reference Cells for Direct Burial Applications
Abstract
Several new permanent reference cells have emerged in recent years with the advantages of smaller size and apparent longer life. The present test program was developed to assess the relative service life provided by various permanent reference cell designs.

Several new permanent reference cells have emerged in recent years with the advantages of smaller size and apparent longer life. The present test program was developed to assess the relative service life provided by various permanent reference cell designs. The natural tendency for the potential of a Cu-CuSO4 reference cell to vary must also be considered. Some causes of this variation may be due to the age of the cell and differences in manufacturing. Four tests (CuSO4 leaching, chloride leaching, dry-out tendencies and "real-world" testing) were performed on six permanent reference cells (PRC) samples. This paper discusses the testing results and how these results can be useful for the development of a standardized test method.

This paper presents the results of the first phase of a Federal Highway Administration sponsored, pooled fund study (twelve states provided supplementary funding) evaluating the performance of water-based inorganic zinc (lOZ) primers on steel bridges. An initial program objective is to better understand failure mechanisms for topcoated and untopcoated water-based IOZ primers. The following results are data from two proprietary water-based IOZ coatings cured under five different sets of environmental conditions. Data gathered includes coating weight loss during curing and film appearance after curing in various environmental conditions. The test conditions include a range of temperatures and humidities including surface temperatures near the dewpoint. Two conditions involved a cycle that included surface wetting. The data generated lend some insight into failure modes that may occur when water-based IOZ coatings are applied under less than ideal conditions. Results to date include data gathered during the curing process. Future work will include accelerated exposure testing of untopcoated and topcoated water-based IOZ applied under the various conditions. Additional cure conditions may be evaluated based on the initial data collected. The work completed also included a review of specifications, manufacturers' suggested application procedures, and curing mechanisms. Some of the more pertinent information collected during this review is presented in the paper.
