Defining the Inspector’s Role and Responsibility an Essential Element of Successful Coating Project

Product Number: 41210-552-SG
Author: Robert P. Maley
Publication Date: 2010

An Inspector’s duties can vary widely from project to project, quite often straying from the traditional observe, verify, and record. This paper examines the plethora of problems that can develop should an inspector be assigned too much or too little responsibility, as well as how best to avoid such developments.

Degradation of Aerospace Coatings Due to Combined Effects of Mechanical Loading and Environmental Exposure

The most effective means to control atmospheric corrosion of aircraft is through the use of protective coatings. In addition to combating corrosion which represents a risk to the safe operation of an asset there are strong economic and environmental drivers to extend the service life of aerospace coatings. Repair and replacement of protective coatings that no longer meet performance requirements generate a significant volume of environmentally hazardous waste which includes the coating material media used for coating removal as well as the waste materials generated in surface preparation and reapplication of the coating system. Development and selection of durable coating systems have often been limited by the ability to produce service-relevant failures in accelerated laboratory tests. Existing accelerated test techniques do not adequately employ the chemical thermal or mechanical stressors that produce damage mechanisms such as coating cracking at structural discontinuities in airframes. Additionally individual coatings may be qualified separately rather than as part of a multi-layer system. As a result current test methods cannot be used for accurate quantification of coating performance and service life. In this work test methodologies previously described that employ combined environmental and mechanical loading are used to excite relevant failure modes of multi-layer systems such as coating cracking at sealant-filled lap joints. The kinetics of moisture ingress coating cracking and damage progression are quantified throughout static and dynamic mechanical tests performed under cyclic atmospheric conditions using in situ measurements of coating properties. It is observed that the coating barrier properties and cracking are dependent on stress temperature and humidity as well as the interaction effects of these parameters.

Successful commercialization of any biomass liquefaction technology will require identification of strutural materials with sufficient corrosion resistance to contain the process fluids for an extended period of time. The conditions under which materials will be utilized will strongly affect the selection of containment materials. For production and processing of bio-oils the materials will be required to perform at temperatures that could be as high as 550 C and for some processes under considerable pressure.Examination of components after extended exposure in operating systems has shown shallow intergranular attack of some stainless steel samples. These studies have identified sulfur as a factor in the degradation and also identified materials that appear to have improved resistance to this intergranular attack.Research sponsored by the Department of Energy's Bioenergy Technologies Office

The EPA estimates it will cost $390 billion over the next 20 years to repair or replace the crumbling wastewater infrastructure. Replacing infrastructure is costly, and in light of current economic conditions and worldwide budget cuts, often impossible to do. Alternatively, the use of single coat, fast cure high performance epoxy linings to rehabilitate sewage pipelines instead of replacing them will save municipalities considerable money and time, making it not only possible but practical for municipalities to protect their local environments today from sewage leaks.

Using dehumidification in shipyards has been a widely accepted practice for three decades. A lot has been learned and techniques have become much more sophisticated but the basic goal of preserving the blasted steel and creating the right conditions for coatings application remains the same. This paper discusses how various combinations of desiccant dehumidification, heating and cooling equipment have been utilized properly and some examples of when things did not work out so well.

Demonstration of Electro-Osmotic Pulse (EOP) Technology to Mitigate Alkali-Silica Reaction in Concrete Pavement

Many private-sector, federal government, and Department of Defense (DoD) facilities experience the problem of concrete deteriorating via alkali-silica reaction (ASR). ASR is a form of concrete corrosion that slowly deteriorates concrete from the inside by forming highly expansive gels that cause cracking and swelling of the concrete matrix. This paper summarizes the results of a project that evaluated Electro-Osmotic Pulse (EOP) technology to mitigate ASR in an area of the visitor’s ramp at Campbell Army Airfield. An EOP system was designed, installed, and monitored in a concrete pavement section affected by ASR. In addition to installing EOP technology, concrete moisture monitoring probes were installed at selected locations. The performance of the EOP system was evaluated by recording temperature and moisture levels inside the concrete for a period of nine months. The ability of the EOP system to mitigate ASR is inconclusive. Although there are indications that moisture is being removed from the concrete pavement, it is not clear that the concrete’s internal relative humidity has been reduced below 80%, the moisture reduction value that ensures ASR will not occur. A long-term approach for performance monitoring must be completed before the technology can be recommended.

The drive to embellish and beautify our surroundings is a human motivation that bridges both culture and time. From vases to vaulted ceilings, across the globe we captivate ourselves with ornament, decorating the objects that we create, the homes we live in and the spaces in which we work and worship. Examples of decorative painting can be found from the earliest moments of man’s existence and have evolved throughout history in synchronicity with our life styles; expressing our tastes, our status, our standards and values.

Densify Faster, Densify Cleaner, Densify Greener: Enhancing polished concrete floors

Specifying polished concrete floors can reduce a project’s material- and energy consumption in both new construction and remodels. As a high-performance, low maintenance floor, it is sustainable throughout its lifecycle. The only gap in its green profile has been the chemistry used to densify concrete in preparation for polishing. New, less caustic colloidal silica-based densifiers solve this problem, as they are safer for workers and less burdensome on the environment. Their use can also help contain costs.

Rebars used in prestressed concrete structures are constantly subjected to tensile stress, and some rebars have been reported to fracture due to hydrogen embrittlement.1 It is important to know the hydrogen embrittlement behavior in rebars to prevent fractures. The effects of environmental conditions such as tensile stress, hydrogen content, and temperature on time to fracture have been evaluated individually;2,3 however, their combined effects have not been clarified. The purpose of this study is to experimentally clarify the relationship between time to fracture due to hydrogen embrittlement and environmental conditions to which the rebars are subjected.

Microbiologically influenced corrosion (MIC) is a key risk to oil and gas infrastructure and confers great cost to asset owners. The AMPP 2021 IMPACT Canada study, which analyzed the energy, manufacturing, and mining sectors, shows the cost of corrosion in Canada is roughly $51.9 billion per year. To break this down further, MIC is estimated to make up roughly 20% of all corrosion which is roughly $10.4 billion in Canada alone, each year.
