Authors:

Various after-the-fact porcelain enamel defects as discussed: surface laminations, melt blisters, outgassing as a result of base metal carbon, fishscale, warpage and/or sag of ware, surface contaminants, and rust. The discussion looks at these porcelain enamel problems as steel related defects. Although due to steel problems, they are not necessarily related to defective steel. The need to purchase the correct steel for the end use application is discussed.

Bubble Structures, Fishscaling Resistance and Adhesion of Vitreous Enamel to Low Carbon Steel

Article

Nov 2011

The bubble structures, fishscaling resistance, adhesion and its mechanism of vitreous enamel to low carbon steels were evaluated by microscopic methods. The results show that the microalloying elements deteriorates the adhesion but suppress the fishscaling tendency, the enamel-steel interface adhesion could be explained as mainly the mechanical interlocking and chemical bonding during the firing process; the lower carbon substrate causes higher proportion of bigger bubbles in the enamel layer and subsequently causes the lower fishscaling susceptibility.

Blistering failure analysis of organic coatings on AZ91D Mg-alloy components

July 2014 · Engineering Failure Analysis

A batch of notebook personal computer components was manufactured from AZ91D Mg alloy by precision die-casting, subsequent chemical conversion and organic coatings. After storage for some time, some blisters were found on some components. SEM/EDS and FTIR analysis showed the blistering initiated because of in situ loss of adhesion at the organic coating/substrate interface, caused by ... [Show full abstract] contamination and/or corrosion. Data from accelerated environmental tests on deliberately contaminated model samples suggested that the blisters originated from contamination at the interface, and that the blistering was also related to the storage conditions. An empty blister forms at early time, and it gets filled with corrosion products later on, and corrosion further on, progress on these sports. An effective way to reduce blister formation is to avoid direct physical contact with all components in this product.

Procedure and Results of Decommissioning of R&D Facility of Uranium Fuel

January 2010

From 1998 through 2005, the facilities for research and development (R&D) of uranium ore-dressing and uranium fuel etc. were decommissioned and soil contaminated by uranium was collected. All the pieces of apparatus in the nuclear facilities which might be contaminated with uranium were treated as radioactive wastes. At the time of the decommissioning activity, there was no specific value to ... [Show full abstract] judge as radioactive wastes. So MMC considered and adopted the pragmatic procedure to judge that soil was radioactive waste or not. During decommissioning facilities and collecting soil, the environmental monitoring was conducted. And it was confirmed that these activities had no influence on the surrounding areas. All decommissioning activities were finished with no difficulty. The wastes generated from the decommissioning activities were packed in the steel containers and have been stored safely in the storehouse built in the same area. In this report, the details of decommissioning activities are described.

Recovery/Recharge and Recycle System for Bromochlorodi-fluoromethane (HALON 1211)

November 1990

The Air Force has an extensive inventory of Halon fire extinguishers, all of which require service and maintenance. When these operations are performed, halon is vented to the atmosphere, resulting in an estimated loss of up to 250,000 pounds of halon per year at a value approaching $500,000. Additionally, these emissions have a significant impact on stratospheric ozone. This project developed a ... [Show full abstract] recharge/recovery system for Halon 1211 to move the agent between vessels without venting, and to simultaneously determine the quality of the halon and remove contaminants. The project was accomplished in two phases. Phase I included a review of the commercial market and a summarization of available components. Phase II involved design, assembly, and testing. Over 200 transfer and recovery tests were performed on the prototype unit. The results of this effort are a prototype recharge/recovery unit for Halon 1211, operation and maintenance procedures, and a purchase description for use by the Air Force in procurement activities.

Effect of Flow Rate on Carbon Filter Performance

August 1963 · American Water Works Association

Carl A. Rambow

This study investigates the fraction of an adsorbed contaminant that can be subsequently removed from an activated carbon filter for analysis and measurement. The study investigated whether the flow rate of 10.2 gpm/sq ft could be substantially increased without seriously reducing the efficiency of removal of organic materials from the water. For the purposes of this study, the variable was flow ... [Show full abstract] rate. It was also necessary to explore the effect of adsorbate concentration at some length, as the proposed application of the carbon filters (field sampling for organic pesticides) involved extremely small concentrations of adsorbate. Such concentrations (1 ppb or less) are difficult to work with in the laboratory, and much of the experimentation was done at adsorbate concentrations two to four orders of magnitude greater, and predictions of performance at lower concentrations were made, in part, by extrapolation of results.

Bonding linerboard with hot melt adhesive

September 2012

P. Haschke

Hot melts are limited in their capability to penetrate low porosity substrates, wet out very rough surfaces, and form bonds in the presence of contaminants. A hot melt adhesive for packaging applications is typically made with specific polymers or copolymers, trackifier resins, diluents and waxes. Using hot melts successfully depends on balancing five principal factors during the bonding process. ... [Show full abstract] The design of the bond can also affect adhesive performance. It is very important that the hot melt application system be properly monitored and maintained. Understanding the specific substrate to bond is important in finding a suitable hot melt adhesive. Substrates can be evaluated for physical, chemical, and surface characteristics to gain information on what types of hot melt adhesives involves making lab bonds under conditions that are as close as possible to the customer bonding conditions.

Influence of oxidation in the ladle on carbon steel quality

January 1989

Mass and large-batch production foundries do not usually monitor the degree of oxidation of the molten steel in the pouring ladles, and consequently have no objective data on the oxygen content of the steel. With a view to optimizing the serviceability of the castings and ascertaining the correlation between the oxygen content and the degree of contamination nature, size, shape and distribution ... [Show full abstract] of nonmetallic inclusions), the authors investigated the behavior of cast steels in low-carbon (up to 0.2% C) and medium-carbon (up to 0.48% C) grades. The results show that as the oxygen activity of the metal is lowered, its solidifies with a finer microstructure and lower inclusion content. The remaining inclusions are smaller and more compact, and do not contaminate the grain boundaries.
