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

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

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.

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. Most paint specifications require reworking a flash-rusted surface to reveal bare steel.  Additionally, most paint manufacturers will not accept liability if their products are applied over some grades of flash rust.  Currently, there is no quantitative or semiquantitative technique to characterize or categorize the level (or grade) of flash rust. However, descriptive and visual standards developed by SSPC, and NACE are available. These standards are routinely used in the waterjetting industry, but they are subjective in nature.   Attempts have been made in the past or are presently being made by different entities to come up with a more definitive methodology but with limited success. The present paper discusses the results of a research effort to develop quantitative or semi-quantitative method (or methods) to characterize the level of flash rust formed on carbon steel after HP or UHP waterjetting.

The objective of this study was to examine the effects of an ultra-high pressure (UHP) waterjetting surface preparation (>25,000 psi) on the performance properties of select marine/offshore coating epoxy systems. Uncoated steel panels had been allowed to rust in an outdoor atmospheric environment and then were subjected to UHP waterjetting

Nonskid coatings are typically used on the flight deck of aircraft carriers and high traffic areas of a ships’ deck. At this time, there are only a few approved materials available for use as nonskid coating for landing areas onboard US Navy vessels. Nonskid coating materials with improved performance, lower cost, and decreased maintenance are currently in development.
