Performance of Autonomous Aerial Robotics for Dry Film Thickness Measurement

Product Number: 51219-177-SG

Author: Jamie L. Branch

Publication Date: 2019

$20.00

Aerial robotics is an emerging technology for coatings and non-destructive testing (NDT). Performing coating inspection measurements, such as dry film thickness (DFT), using aerial robotic systems improves occupational safety and reduces injuries and deaths attributed to falls. This is done by allowing measurements to be taken with the worker safely on the ground. As the industry advances towards adopting drones/aerial robots as tools for inspection practices, it is critical to evaluate the associated performance and limitations

Various polymeric coatings have been exposed to natural saltwater environments in Buzzard' s Bay, MA and at La Costa Island, FL for the last 18 years and 21 years respectively. The coating systems were applied to 8 inch (20.32 cm) by 8 inch (20.32 cm) by 40 feet (12.19 m) A36 steel "H" pilings. The depth of the water ranged from 4 feet (1.22 m) to 8 feet (2.44 m). Periodic visual inspections have been conducted to evaluate the performance of the coating/ primer systems in the splash zone and in the immersed zone. The coatings had windows to evaluate the under film corrosion attack by saltwater present near the Cape Cod canal. The coatings were evaluated according to ASTM visual standards at low tide. Results of the coating inspections and an evaluation of their effectiveness in preventing the corrosion of steel pilings in seawater will be presented.

Performance of Damaged Thermal Spray Coatings in Phase Change Materials (PCMs) Used in Geothermal Plants

In the landscape of transitioning to clean energy sources, geothermal energy is likely to be a key player in the energy mix. Geothermal energy technology has expanded its scope from primarily serving the electricity market to encompass a wider array of applications within the energy sector. This evolution includes sustainable heating and cooling solutions, making geothermal energy a dependable and cost-efficient source of renewable power, unaffected by weather conditions. However, corrosion poses a significant challenge in numerous geothermal facilities, exerting a considerable adverse influence on the economic viability of the geothermal sector. The capacity to engineer surfaces to combat corrosion represents a valuable tool for both engineers and plant operators, enhancing maintenance and repair practices. This paper explores the possibility of using thermal spray coatings on steel substrates and modify its corrosion behaviour in phase change materials (PCMs) used in geothermal plants. The selection of thermal spray coatings was guided by factors such as their documented performance, applicability, accessibility, and cost-effectiveness. The philosophy was to select coatings that were anodic to the substrate in molten PCM that would protect the substrate in case of any damage to the coating. Carbon steel substrate with thermal spray coatings of Al was prepared, artificial defect was created, and the specimen were exposed to molten nitrate-nitrite PCM at 165°C for 168h. After testing, the specimen was visually examined and detailed post-test characterisation [light and electron microscopy (SEM/EDX) etc] of surface and cross-sections was carried out. These measurements provided an indication of performance of the coatings and allowed further understanding of the mechanism of degradation of materials in nitrate-nitrite PCM in the presence of artificially-introduced through-thickness coating defect. The study showed that thermally sprayed aluminium (TSA) could provide a possible corrosion mitigation pathway for carbon steel structures in nitrate-nitrite based PCM systems even when damaged.

Performance of Distributed Galvanic Anode Systems in Bridge Structures

Product Number: 51323-19214-SG

Corrosion of reinforcing steel is recognized as the major cause of the deterioration of reinforced concrete structures. Exposure to de-icing salts, seawater and chloride-containing set accelerators, plays a significant role in reinforcing steel corrosion (Figure 1). When the chloride content at the rebar level exceeds the threshold for initiation of corrosion, the passivation protective film on the rebar surface is destroyed and a corrosion cell can form either on the same piece of rebar with anodic and cathodic sites adjacent to each other, or a macro-cell between two different layers of reinforcement.

Performance of Distributed Galvanic Anode Systems on Bridges in the United States

Embedded galvanic anodes designed to protect reinforcing steel in chloride-contaminated concrete adjacent to concrete “patch” repairs were developed in the late 1990’s. The original concrete anode was puck-shaped and consisted of high purity zinc encased in a mortar formulated with high porosity and lithium hydroxide to maintain a pH greater than 14 to keep the zinc active over the life of the anode. This approach of a high pH mortar around the zinc to prevent anode passivation is commonly referred to as alkali-activation.

The subject of hydrogen stress cracking of various high strength Nickel alloys has recently been reported by others. Comparisons of results for different test methods including Slow Strain Rate Testing (SSRT) and Incremental Step Loading (ISL) were performed.A new Ni-Cr-Mo-Fe alloy known as ATI 830™ alloy (N08830) was recently tested to determine its resistance to Hydrogen Induced Stress Cracking (HISC) simulating conditions arising during cathodic protection in a subsea environment.The unique set of test methods and conditions included SSRT and ISL all using precharged specimens with ongoing continuous charging during testing. Test specimens utilized different geometries including smoothed and notched along with round and rectangular cross sections.The paper draws key conclusions based on comparisons of test methods and also compares N08830 alloy results to other high strength CRA’s used in Oil and Gas subsea production equipment.

Nuclear power has been the largest source of carbon-free power in the U.S. (and much of the developed world) for almost a half century. As such, in the U.S. today, nuclear power plants of the Light Water Reactor (LWR) design generate 20% of all electricity, comprising over half of carbon-free electricity generation. In order to meet the short-term 2030 greenhouse gas emission reduction target, the existing nuclear fleet will play an important role, while the development and deployment of advanced reactors such as the small modular reactors (SMR) of the LWR design can be accelerated.

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.
