... ABSTRACT Corrosion measurement and monitoring with correlation to corrosion rates can now be applied directly in the field with a new stand-alone hand-held potentiostat/galvanostat in combination with a new in-house diagnosis software of electrochemical current noise. As an example...

... Abstract The objective of this work was to study the effect of the total acidity and of the hydration on the corrosiveness of fuel ethanol. At the first part of the study, different ethanol samples with different total acidities were produced by: adding acetic acid in different quantities...

... for these packaging crates and few corrosion problems with the wires were observed. Recently, copper based alternatives to zinc naphthenate have been used, and corrosion problems have been observed. Here, we present the results of laboratory corrosion testing of 10 different wood treatments to see which...

... ABSTRACT External corrosion direct assessment includes four steps in the SP ECDA standard practice as a recommended methodology. The first step in the process is the pre-evaluation and the fourth step is the post assessment; we propose the first step to include the integration of macro...

... INTRODUCTION ABSTRACT The corrosion rates of type 1010 carbon steel, and types 304 and 316 stainless steels in saturated solutions under salt deposits were measured using coupled multielectrode sensors. The measurements were carried out in the presence of the following salts: KCl, NaCl...

... ABSTRACT H2S liquid scavengers are used up stream of gas sweetening and dehydratation processes. The scavengers capacity to remove H2S and their corrosivity properties in presence of other chemical treatments were evaluated. Compatibility with corrosion inhibitors and asphaltene dispersents...

Stack lining, using an appropriately corrosion-resistant metallic material, has proven to be an effective means...

... and polarization techniques. A limited number of measurements were made in the standard NACE TMO177-90A and TM0284 acidic sour solutions. Results in the alkaline sour environments indicated an increase in the corrosion and permeation rates with increasing pH and bisulfide (HS-) concentration. In the presence...
