Color-Based Assessment of Flash Rust

Product Number: 41210-556-SG

Author: Andreas W. Momber

Publication Date: 2010

$20.00

The presentation reviews the utilization of color analyses for the assessment and rating of rust, whereas particular attention is spent to flash rusting. The background of flash rust formation is discussed first, along with a brief review about the composition of flash rust. The fundamentals of the HSV color model, which is selected as a simple suitable model, are introduced. Finally, the author discusses the utilization of the suggested approach for the evaluation of steel substrate cleanliness and flash rust assessment.

Evaluating the Flash Rust Protection of Water-Based Cleaners and Their Role in Surface Preparation

Product Number: 51324-20745-SG

Author: Lisa Marston; Luke Stone

Publication Date: 2024

$40.00

In metalworking processes, contaminants can interfere with future processing steps and may accelerate corrosion on metal parts. As such, a cleaning step is often implemented prior to coating or packaging finished parts. Industrial cleaners are typically water-based with blends of surfactants, co-solvents, chelating agents, and/or flash rust inhibitors. While accelerated corrosion tests such as humidity and salt fog exist, they are typically too aggressive for the evaluation of flash rust inhibitors in cleaners which are not meant to provide long-term corrosion protection. There is a need in the industry for a quick and reliable way to select a cleaner that meets the needs of the application and is compatible with the overall process. A screening method to compare the flash rust protection ability of various water-based cleaners was investigated. Modified vapor inhibiting ability (VIA) testing and linear polarization resistance (LPR) tests were performed on carbon steel plugs treated with several cleaners. Industry standards currently recommend that any detergent or cleaner be removed from metal surfaces prior to applying coatings. When evaluating cleaning processes where coatings will be subsequently applied, adhesion testing should be paired with the screening test. The effects of various cleaners on adhesion of a waterborne acrylic coating were investigated.

Experimentation to Develop a Quantitative Method for Characterizing the Level of Flash Rusting Formed on Carbon Steel after Ultra High Pressure Waterjetting

Product Number: 41206-253-SG

Author: Moavin Islam, Wayne McGaulley, James Tagert

Publication Date: 2006

$20.00

High pressure (HP) and ultra-high pressure (UHP) waterjetting for coating removal and surface preparation has several advantages compared to the industry standard abrasive grit blasting process. However, a major drawback of waterjetting is subsequent flash rusting of the steel surface. The color of the flash rust is typically orange, red, or brown of various shades depending on the color of the underlying steel, the nature of the surrounding environment, and the duration of exposure to the environment.

How Can New Coating Technologies Secure Long Lasting Corrosion Protection even under Unpredictable Surface Conditions?

Product Number: MECC23-20116-SG

Author: Anders Solli; Anders Skilbred

Publication Date: 2023

$20.00

All ships need periodic maintenance, either onboard a FPSO, in a water ballast tank or a hull side of a marine vessel. When preparing for maintenance of such structures it has been standard practice to sandblast the surface. Sandblasting creates superb surfaces for coating application with ultimate cleanliness, but due to the dust generated by the process it is facing more local restrictions due to environmental impact and HSE.

Implementation of Pulsed Laser Ablation Technology in Surface Preparation Processes

Product Number: 51324-20982-SG

Author: Matt Binsfield

Publication Date: 2024

$40.00

The transition of pulsed laser ablation (PLA) technology into the hands of maintainers within shipyards and the transportation industry requires an assessment of multiple factors. From the technical perspective relative to surface preparation and corrosion mitigation, it is essential to understand the impact of PLA energy into substrates and the resultant adhesion characteristics of subsequent coatings. Technical areas to be discussed include metallurgical properties, such as stress corrosion cracking, weldability, bulk properties, fatigue life, as well as adhesion. The effective application of laser ablation is of critical concern to preservation professionals, which requires an understanding of how the process works, the proper appearance of a laser ablated surface, whether that is a tightly adhered existing coating prepared for re-coating, or to expose some or all of the base metal substrate. Accordingly, both laser operators and inspectors need specific information and training to appropriately use the technology to meet preservation objectives and requirements. These needs will be addressed through a forthcoming AMPP Laser Ablation Standard, Technical Guide, and Visual Guide. Determining where to apply PLA based on extensive test data currently available, as well as understanding where future investigation is required, will be summarized.

NACE SP0716-2023, Soluble Salt Testing Frequency and Locations on Previously Coated Surfaces

Product Number: NACE SP0716-2023

Publication Date: 2023

$109.00

Asset owners, engineers, consultants, coating contractors, inspectors, and others are specifying allowable levels of surface soluble salts to prevent premature coating failures. The purpose of this standard is to provide guidance about the number of and locations for soluble salt tests on steel surfaces.

This standard establishes siting and frequency requirements for soluble salt testing before the application of a subsequent coating system to previously coated substrates and replacement substrate material. It does not include allowable limits of soluble salts, which are typically addressed by the procurement documents or the coating manufacturer’s documentation.

Performance of Marine Coatings Applied over Flash Rusted Surfaces

Product Number: 41209-465-SG

Author: J. Peter Ault, Steve Cogswell

Publication Date: 2009

$20.00

This paper investigates a key concern with Ultra High Pressure Waterjetting (UHPWJ) surface preparation – the impact of “flash rusting” on coating life. Flash rusting can occur under certain environmental conditions when the steel is left sufficiently wet following UHPWJ. Reducing or eliminating flash rusting can increase the cost of surface preparation. However, flash rust’s impact on coating life is debated.
