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.

Anomalous localized corrosion of submerged steel H-piles was detected in a Florida bridge spanning over a brackish river. Microbiological and chemical analysis of the waters samples showed high population of sulfate reducing bacteria (SRB) and high concentration of sulfate ions. The steel piles had noticeable heavy marine growth which were thought to have an effect on corrosion process by supporting biofilm development creating localized corrosion and differential aeration cells. As part of ongoing research to identify the role of physical properties of macrofouling on the aggravation of microbiologically influences corrosion(MIC) of submerged steel bridge the objective of the work presented here was to identify the influence of microbe availability to promote SRB proliferation under occluded and porous fouling spaces and development of MIC there. Both laboratory and field exposure tests were conducted. Laboratory experiments were carried out in nutrient-rich environments inoculated with SRB with both occluded and porous crevice conditions characteristic of hard and soft marine fouling. Field exposure tests included long term exposure of steel coupons subjected to varying submersion depths in the river at the Florida bridge site. Electrochemical tests included the measurement of open circuit potential (OCP) linear polarization resistance (LPR) and electrochemical impedance spectroscopy (EIS). It was confirmed that SRB proliferation can occur as the macroorganism can accommodate different environmental condition. Occurrence of severe corrosion conditions was shown to be possible in the presence of macrofoulers and SRB.

This paper focuses on the corrosion behaviour of high strength flexible wire material immersed in de-aerated 3.5% NaCl solution under 40bar CO2 partial pressure at different test temperatures: 30°C, 40°C and 60°C; different CO2 fluxflux: 0.1ml/min/cm2 and 0.0008ml/min/cm2; different volume of solution to surface area of sample (V/S) ratios: 1ml/cm2 and 0.3ml/cm2 and test durations: 2 and 4 months. The tests were carried out in a lab-scale test system designed and built at TWI Ltd for the simulation of complex annulus environments. The corrosion rates and the maximum depth of the localized attack for tests at different temperatures were recorded as: 30°C>60°C>40°C. This is linked with the stability, structure and thickness of the precipitated iron carbonate scaling. The lowest corrosion rate was recorded for the test with the lowest V/S and slowest CO2 flux, linked with a thin and compact iron carbonate layer. The effect of the flow and degree of confinement are significant at high CO2 partial pressures.

The success of corrosion protective coating systems relies, to a great extent, on the coatings’ inherent barrier properties. This barrier property signifies the coating’s ability to withstand the permeation of sea water and oxygen, thus minimizing corrosion of the underlying metal. While various additives or pigments can promote the barrier property of coatings, one of the most common pigments is aluminum flakes [1-4].The idea behind their use is simple, and essentially relies on having the aluminum flakes in the coating oriented parallel to the underlying substrate. With them in place, the pathways for sea water and oxygen effectively increase, thus preventing the progression of corrosion. However, while having been employed in numerous coating formulations for many years, the evidence for the success of aluminum flakes as barrier pigments is still lacking.

Cleaning, restoration and conservation of murals and decorative paintings are three vastly different definitions. Murals get dirty over time. To wash them with a non-invasive cleanser is to “clean” them. You could clean a mural with de-ionized water or mild cleansers. Blowing the dust off with light compressed air, soft bristle brushing or chemical sponging is also considered cleaning. Once we step from a surface dirt removal to a yellowed varnish removal, or penetrated dirt removal, we have entered the conservator’s field.

Extended Connectivity of Zinc Pigments to Provide Enhanced Galvanic Coupling by Partial Replacement with Nanoparticles

Product Number: 51319-13470-SG

Coatings are widely used to mitigate corrosion of highway steel bridges in aggressive exposure environments. Zinc-rich-primer three-coat (ZRP) systems have been used since the 1980’s. However coating failure of ZRP has been identified within 15 years of application well short of typical 75 year bridge design service life. Most of the reported coating failure included corrosion undercutting blistering and delamination. Partial replacement of zinc pigments with nanoparticles in ZRP coating systems have been shown to provide beneficial physical chemical and mechanical properties. These enhanced qualities may provide enhanced performance to mitigate premature coating failure. Earlier research showed that the nanoparticle enriched primer provided comparable corrosion resistance in aggressive environments as conventional three-coat systems. Nonetheless coating performance can be compromised by inappropriate surface preparation before coating application. Exposure to high humidity and surface contaminants (hygroscopic salt) as well as noncompliance to proper anchor profile requirements can initiate coating failure. The purpose of this study was to evaluate the effect of surface preparation with varying surface contaminants on the corrosion performance of a nanoparticle enriched zinc rich epoxy coating (NPE-ZRP) system. Adverse environmental condition exposure to different level of humidity (5% 75% and 100% RH) water immersion and salt contamination were incorporated before the coating application. After adverse exposure NPE-ZRP coating and a traditional ZRP coating (as a reference) were applied over the coupons. Cyclic testing in alternate wet/dry exposure was done for ~5 months. Coating and corrosion behavior was analyzed during the wet exposure of the cyclic testing by Open Circuit Potential (OPC) Linear Polarization Resistance (LPR) and electrochemical impedance spectroscopy (EIS). Physical parameters such as changes in coating thickness pull-off strength and cross-sectional micro-graphic analysis were also assessed to elucidate the extent of coating degradation.

Extending Asset Lifecycle With Inspections And Maintenance

Product Number: 51322-18143-SG

Author: Tim Widing, Cortney Chalifoux

Publication Date: 2022

$20.00

Consistent coating inspections and planned maintenance are essential to asset integrity. Non-existent, delayed, and cursory inspections can allow premature coating breakdown, corrosion, and costly failures. On the other hand, improper maintenance can be ineffective, costly, and wasteful. The challenge involved in executing informative inspections and effective maintenance practices is identifying and understanding the numerous conditions that can contribute to a reduction in the lifecycle of an asset. This paper will discuss some of the aspects involved in identifying coating conditions that are likely to result in failures and developing cost effective coating repair strategies that will extend the life of the asset.

“Tilt-up" is a state-of-the-art building system in which steel reinforced concrete panels are cast on site and tilted up into their final position. The tilt-up panels are load bearing and also function as cladding elements. With the exceptions of integrally colored concrete, tilt-up concrete panels can look bare and unattractive if a finish is not applied. It is also well known that concrete is not a “perfect” material as it shows porosity and micro-cracks which can lead to deterioration over time.
