...RESULTS AND DISCUSSION The interaction of the metals at the solid/electrolyte solution interface, under conditions in which the corresponding metal solutions were stable, was investigated by adsorption measurements and plotting the corresponding adsorption isotherms for cadmium, nickel, copper...

...Abstract The nuclear waste disposal concept in Finland is based on a multi-barrier system, where the spent nuclear fuel is disposed of in deep crystalline bedrock in copper canisters surrounded by bentonite clay buffer. The copper canisters should have lifetimes exceeding 100 000 years to prevent...

..., greatly reducing the impact of high levels of halogen on the corrosion of copper and copper alloy heat transfer surfaces. This paper will outline laboratory corrosion testing and film formation and finally field applications. Copper Copper Alloy Admiralty Brass Corrosion Inhibitor INTRODUCTION Copper...

... facility in Groß Schönebeck (Germany), massive copper precipitation has been observed downhole clogging the production well. Occurring mechanisms and measures to prevent copper precipitation or scaling needed to be investigated. This contribution deals with the evaluation of the corrosion behavior...

...Abstract Copper (Cu) is one of the candidate waste container materials for high-level radioactive waste geologic disposal systems located in the saturated zone, because of its thermodynamic stability in anoxic water. However, species in the groundwater could change Cu stability and electrochemical...

.... ⁶ The coated wafers were sectioned, and a copper wire was electrically connected to the film. The sections were then coated with epoxy to expose a 14 mm diameter circle of the film. The epoxy was cured per the manufacturer directions. The electrochemical behavior of the monolithic thin films...

... with tungsten, copper and nitrogen. The material type of the alloy complies with the condition for type 4d of nickel based alloy in ISO15156-3. The strength of the material is enhanced by alloying nitrogen and cold working so that it can be achieved to 125ksi of yield strength. The developed alloy has...

... electron mediators accelerated the MIC of C1018 carbon steel by nitrate reducing Pseudomonas aeruginosa. ²⁴ This is not surprising because NRB MIC against carbon steel is analogous to SRB MIC against carbon steel, both belonging to EET-MIC. ⁹ Copper is much less energetic...

...Brass is defined as “an alloy consisting mainly of copper (>50%) and zinc, to which smaller amounts of other elements may be added” ¹ . Brass is an important industrial alloy valued for its thermal and electrical conductivity, corrosion resistance, strength, and ductility. Brasses...
