Comparison Of Atmospheric Corrosion Of Silver Across Multiple Locations

Product Number: 51322-17621-SG

Author: Douglas C Hansen, Ronald Zeszut, David Rubino

Publication Date: 2022

$20.00

Atmospheric corrosion of bare metals is a constantly occurring process that can cause significant damage to metal components and structures. For this reason, it has been extensively studied, especially for steel and aluminum alloys.^1-8 Environmental exposure testing is a common method for studying and characterizing the corrosion severity of a location, which allows for comparison with other regions. Much of this data collection is directed toward development of predictive models for corrosion processes, with the goal of estimating corrosion damage based on environmental conditions.

Correlation Studies between Outdoor Exposure and Accelerated Laboratory Corrosion Tests in Cold Alaskan Climate

Product Number: 51323-19384-SG

Author: Raghu Srinivasan, Tyler Cushman

Publication Date: 2023

$20.00

Atmospheric corrosion of metal alloys in cold environments is assumed to be negligible. However, studies in the Arctic and Antarctic regions have shown significant corrosion damage when exposed to cold conditions. While thermodynamically this is correct, other factors in such environments can be responsible for driving corrosion.

Corrosion Under Insulation And Atmospheric Corrosion In The Refinery Industry. An Accurate Approach To Estimate Corrosion Growth Rates, A Texas Refinery Case Study

Product Number: 51322-17751-SG

Author: Bernardo Cuervo, Mark McQueen

Publication Date: 2022

External corrosion in uninsulated pipelines is normally able to be prevented by cathodic protection (CP). Generally, external corrosion on buried pipelines cannot occur if CP current is getting onto the pipe. CP is an electrochemical means of corrosion control in which the oxidation reaction in a galvanic cell is concentrated at the anode and suppresses corrosion of the cathode (pipe) in the same cell. For instance, to make a pipeline a cathode, an anode is attached to it.

Hydrogen embrittlement is a process that results in a decrease of the ductility of metals as a result of absorbed hydrogen. Advanced high-strength steels used in the automotive industry are materials that are considered prone to hydrogen embrittlement. Hydrogen can enter the material during steelmaking or processing steps, such as pickling, cleaning, phosphating, and electroplating.

Corrosivity Mapping as a Fundamental Tool in Assessing the Integrity of the Distribution/Transmission System for the Electricity Trust of South Australia

Product Number: 51393-93638-SG

Author: King, G.A.

Publication Date: 1993

The aggressiveness of the atmospheric environment can be assessed by measurement of climatic and pollution factors, or by determination of the corrosion rates of metals and coatings. The latter is a low cost technique which has traditionally been employed at single isolated sites with different types of environments. This approach does not, however, adequately portray the levels of corrosivity across a city or region which can vary by an order of magnitude. A technique has been devised at the Commonwealth Scientific and Industrial Research Organization (CSIRO) in which specimens are exposed across a grid of contiguous sites and the results computer contoured to generate corrosivity maps. A new method of h hyperbolic interpolation of the data has been developed to model corrosivity approaching the coastline. The paper presents results from surveys around an industrial point source of S02, conducted over two different periods. The technique of corrosivity mapping was demonstrated to be a sensitive indicator of localized zones of enhanced corrosion, and the two maps reflected changed conditions in the plant's operation in the two periods. The paper also discusses corrosion mapping in countries other than Australia and examines the costs of such exercises and the potential savings they can provide.

Development of Test Sites in Alaska to Study Atmospheric Corrosion Using Adjustable Test Racks

Product Number: 51324-21000-SG

Author: Raghu Srinivasan; Jozef Hunter

Publication Date: 2024

$40.00

In colder regions, heavy snowfall and pronounced freeze-thaw cycles introduce complexities to the established paradigms governing atmospheric corrosion. To elucidate the mechanisms of atmospheric corrosion under Arctic conditions, four distinct corrosion test sites were established in Alaska, each representing a unique corrosive environment. Each site was equipped with a modern, multi-angle corrosion exposure test rack coupled with an auxiliary weather station. Two additional multi-angle racks are introduced, offering enhanced flexibility and efficiency in research deployments. Innovation is in the design of modular corrosion test racks that can be adjusted to three different exposure angles. Within these setups, five different metal alloy specimens were exposed at three different angles and different lengths of time. Following exposure, the specimens underwent analysis to determine corrosion rates and weather parameter correlations.

Structural steel, which is a critical component of many infrastructures, can suffer from deterioration of steel by reaction with air and its pollutants known as atmospheric corrosion when exposed to the
environment. The risks associated with corrosion of newly-built and ageing infrastructure are high and their consequences costly. The recent International Measures of Prevention, Application, and
Economics of Corrosion Technologies (IMPACT) study led by NACE International (now renamed as
AMPP) has shown for Canada the estimated annual corrosion cost to be $51.9 billion, which is 2.9
% of Canada’s GDP.
