Disposal of Bituminized and Other Low- and Medium-Level Wastes: Waste Characterization and the Retention of Migrating Radionuclides by Steel Corrosion Products
… systems, the sorption characteristics of steel corrosion products were investigated with a special emphasis on competitive sorption between Sr and Na. The corrosion rate of steel exposed to various environments was studied qualitatively and, with some systems, quantitatively. Traditional and …

The Effect of Ion Implantation on the Corrosive-Wear Resistance of Ti-6A1-4V.
… itself but on its size, shape and reaction products. Many surgical implant devices are subjected to wear and fretting processes which generate wear debris and corrosion products. Large volumes of corrosion products or wear debris can elicit a tissue response and may have a systemic effect in …

Romarchite and Other Corrosion Phases on Metal Artifacts from the Queen Anne's Revenge (1718)
… were studied and a preliminary assessment of the corrosion products that have formed on them is presented. Artifacts made of iron, lead, tin, copper, mercury, gold, and silver were recovered from the site with only those made of precious metals displaying no corrosion products. Detailed analysis …

CREEP CORROSION OVER PLASTIC ENCAPSULATED MICROCIRCUIT PACKAGES WITH NOBLE METAL PRE-PLATED LEADFRAMES
… were observed to be caused by the bridging of corrosion products across lead fingers. This phenomenon was identified as creep corrosion and was the motivation for this work. This dissertation advances the state of knowledge on the creep corrosion process and the strategies for mitigation. A …

Atmospheric Corrosion of Ag and Cu with Ozone, UV and NaCl
… electronics and are susceptible to atmospheric corrosion. They are also good corrosivity monitors used to evaluate aggressiveness of the environment. Unfortunately, laboratory exposure testing does not always represent field environments very well. Discrepancies between lab and field exposure …

Adsorption at Treated Steel-Paint Interfaces
… binding that prolongs coating lifespans and corrosion inhibition. Particular steel surfaces are characterised before and after almandine garnet abrasive blasting. Significant build-up and coverage of abrasive residue (almandine and calcium carbonate) is identified on the post-treatment steel, …

Species Chemistry and Electrochemical Separation in Molten Fluoride Salt
… presented by this reactor is that fission products may leak into the primary system from its TRISO particle fuel during normal operation. Consequently, the circulating fission products within the primary coolant would be a potential radioactive source. On the other hand, the containment …

Multiphysics modeling of activity transport and evolution of CRUD and steam generator oxides in pressurized water reactors
Fouling deposits of corrosion products on fuel cladding, known as crud, in the core of light water reactors can cause a variety of operational issues. Buildup of radioactive crud and corrosion products on ex-core structures, such as steam generators and piping, can cause increased radiation fields …

Dissolution, Transport, and Fate of Lead on Shooting Ranges
… lead corrodes rapidly and develops a coating of corrosion products. The type and amount of corrosion products found on lead shot and bullets are best understood through examination of Eh-pH relationships. X-ray diffraction analysis identified hydrocerussite (Pb₃(CO₃)₂(OH)₂) as the corrosion phase …

XRF and the Corrosion Environment at Camp Lawton: A Comprehensive Study of the Archeological Microenvironment of a Civil War Prison Camp
… between a given ferrous metallic artifact's corrosion environment (the surrounding soil matrix) and the subsequent corrosion products formed on the artifact. The hypothesis is that the data will demonstrate a chemical correlation between the two. Iron and chlorine are the two major elements …

Evaluation of tests for porosity and defects in PVD and electroless coatings.
… roughnesses was investigated using porosity/corrosion tests. The tests used were the neutral salt spray test, ferroxyl test, sulphur dioxide test and the copper cementation test. Additionally the effect of radii on the corrosion resistance and porosity of electroless nickel coatings was …

In-operando techniques for early-stage corrosion
… approaches are investigated to study corrosion at the solid/liquid interface, at a higher spatial and temporal resolution than previously possible. Corrosion remains a pernicious concern for metallic structure stability. This is evident in the common case steel in contact with water, …

Role of Nanophase Oxides in Short-Term Atmospheric Corrosion of Structural Steels
… the development of nanophase iron oxides in the corrosion products of carbon and weathering steel were performed to understand the role of nanophase oxides in short-term atmospheric corrosion. Similarities and/or differences between short-term and long-term atmospheric corrosion were established …
