Soluble Salt Opinions?

May 17, 2017
Elzly Technology Corporation is conducting a survey of coating inspectors on the detection and remediation of soluble salts. We invite all coating inspectors to participate in the survey. The survey should take most users 10-15 minutes to complete (dependent on the extent of experience with salt detection and remediation). The survey can be accessed at the following link:

This paper describes the development of an expert tool for vehicle design that assists the designer in avoiding bad design decisions which may cause corrosion problems during the life of the vehicle. The tool is an autonomous agent installed as part of designer's CAD/CAE system. It uses a Hybrid Expert Production System containing Rules in its Knowledge Base and both an Inference Engine that compares these stored Rules with the information (Facts) provided by the designer and CAD/CAE software and a Bayesian Network for processing uncertainty in the facts and rules. An important enhancement in this system not found in most Expert Systems is an Uncertainty Processor. The Bayesian Net calculates the cumulative uncertainty determined by propagating and combining the estimated error found in each and every Rule and Fact used in the chaining logic required in arriving at the proposed final conclusion. Also included is a Knowledge Acquisition Facility used by corrosion and vehicle design experts to load supporting knowledge and Rules into the Knowledge Base and an on-demand Explanation Facility to detail the logic used by the system to arrive at the conclusion. The model is verified by simulating the galvanic corrosion of a truck door latch during Accelerated Corrosion Testing.

Coatings are complex engineered materials that are used in applications with varying performance requirements. The engineer or designer who is specifying the materials will typically rely on manufacturers' published data or recommendations from the manufacturers' technical sales staff. While the information supplied may be valid data, it is not typically based on performance in the specific application or environment being considered. The data used to support design decisions are typically standardized test results developed in the laboratory to quantify basic performance attributes of the material. If a project is of sufficient size or coating failure will have major consequences, application-specific testing may be justified. The cost impact of a coating design decision on a project may be sufficient to warrant an up-front investment in a test program that will provide specific data on which a decision can be based. Typically such test programs are not considered early in the planning process. As a result, there is simply not enough time to conduct the necessary testing. It is a timing issue, rather than excessive cost, which results in design decisions that are based on insufficient data, This paper will discuss three questions that we addressed with testing programs. The answers to each of these questions can impact coating project design and planning. Each discussion highlights the data collected and its potential impact on a coatings project. The three questions are: ? How does the performance of low temperature cure coatings vary with application temperature? ? What are the effects of surface salt contamination on coating performance? ? What effects can improper mix ratio have on performance?

Mitigating Corrosion of Electronics
Abstract
Electronic components drive almost every important piece of tactical and support equipment utilized in the Department of Defense. Often during acquisition of this equipment, the ability of the ?brains? of the equipment to withstand the environment on its own accord is overlooked in lieu of the piece of equipment as a whole.

Electronic components drive almost every important piece of tactical and support equipment utilized in the Department of Defense. Often during acquisition of this equipment, the ability of the ?brains? of the equipment to withstand the environment on its own accord is overlooked in lieu of the piece of equipment as a whole. Additionally as technology advances, new electronic systems are being embedded in older assets that were not designed to enclose such systems. The intent of this paper is to familiarize the reader with various means of electronics corrosion and provide guidance on primary engineering considerations.

Despite improvement in organic coating technology, accurate prediction of service life continues to be problematic. Several models have been developed by various authors who describe the failure of protective coatings. Generally these models describe ionic migration to the coating/substrate interface or describe the breakdown of the polymer chains resulting in gloss and color changes. This paper discusses these models relative to various marine coating service environments. Relationships between the typically scientific models and more practical field coating observations will be drawn. Finally, the paper discusses the prospect for simulating or predicting coating performance.
