By exposure and electrochemical tests in the laboratory the Cu-effect on corrosion behavior of carbon steel, high-alloyed steels and Ti-alloy can be assessed.
Critical materials specific properties were determined by static exposure and electrochemical tests in an artificial geothermal water with high salinity and low pH, containing Cu. Conclusions were drawn using characteristic potential values.
It could be shown that significant Cu-deposition and -precipitation only occurred in combination with carbon steel. High-alloyed materials (S31603, S31653, S31700, S31703, S31803 and N08904) prevent the disturbing Cu-agglomeration. Therefore, they are suitable to be chosen for future design of the piping system, either in massive or in cladded form, if formation of crevices with non-metallic materials can be excluded.
From the interactions and pitting corrosion point of view, R50400 seems to be most favorable.
This contribution provides current findings regarding materials susceptibility for carbon capture, utilization and storage (CCUS) applications. Basing on results gathered in 2 German long-term projects (COORAL and CLUSTER) suitable materials are introduced as well as dominating impurities of the CO2-stream and corrosion mechanisms. Investigations cover the whole CCUS process chain and provide material recommendations for certain parts.
This textbook fulfills its dedication of being the “essential reference for the field, featuring protocols, analysis,fundamentals and the latest advances” of impedance spectroscopy to its readers. It really provides an insight in all facets of this powerful technique.
It should not be missed in the bookshelf of electrochemists and all other interested researchers and engineers who want to be on the current state of this technique.

The second edition of this textbook on physical electrochemistry, written by two experienced teachers of physical chemistry, corrosion engineering and materials science and engineering, covers the current knowledge which should be transferred to students of these fields.
In 20 chapters the fundamentals of electrochemistry, the most important electrochemical measurement techniques and applications of electrochemistry are covered.
It can be concluded that this study fulfills its intension of “serving as a key textbook in undergraduate courses” dealing with electrochemistry and being “a reference source for graduated students, researchers and engineers” interested in this field. Teachers will find sufficient content for preparing lectures on this topic. Even self‐learning is well supported by the clear structure, presented content and provided sources for further reading.
This work examined the factors that influence the droplet corrosion of CO2 pipeline steels caused by oxyfuel flue gases in dense phase CO2 at 278 K, simulating the underground transport conditions. The wetting properties were studied by contact angle measurement, revealing pH and time dependency on the reactive wetting behaviors of carbon steel X70. Exposure tests with CO2 saturated water droplet on steel surface showed that the impurities (220 ppmv SO2 and 6700 ppmv O2) diffused into the droplet and then reacted with metal surfaces in dense phase condition, forming the corrosion products. The corrosion rate was confirmed strongly depending on the droplet volume as well as the SO2 concentration. Condensation experiments carried out on freshly polished coupons in CO2 with 200 ppmv H2O, 220 ppmv SO2 and 6700 ppmv O2, showed that the formation and aggregation of droplets is time and temperature dependent. At 278 K, condensation happened stronger and the corrosion products, mainly consisted of dense hydrated FeSO3/FeSO4. While at 288 K, more fluffy corrosion products consisting of iron oxide/hydroxide and hydrated FeSO3/FeSO4 were found. Further exposure tests on carbon steel coupons with different surface roughness did not reveal the difference in weight loss/gain and therefore the corrosion rate.
This contribution provides current findings regarding materials susceptibility for carbon capture, utilization and storage (CCUS) applications. Basing on results gathered in 2 German long-term projects (COORAL and CLUSTER) suitable materials are introduced as well as dominating impurities of the CO2-stream and corrosion mechanisms.

Since materials play an important role when designing and servicing industrial facilities. Also, for energy systems there is no way around. Selection of appropriate materials is an essential aspect for successful application and reliable service life. Future engineers must be made aware on the importance of this fact. So, they may prevail in techno‐economic discussions.
The book fulfills its intension of providing to students in science and engineering a comprehensive understanding of different energy processes and what role materials play in this conjunction. Also, it gives interested engineers and scientists an insight in this matter. After being introduced the user should dig deeper in the existing detailed knowledge available for materials selection within these special conditions to assure a reliable operation of the energy production facility.
Dictionary of Metallurgy and Metal Processing - English-German – German-English (Book review)
(2019)
The first issue of this classic dictionary contains highly specialized terms, not only of the area of metallurgy but also of welding, soldering and corrosion. Special attention was paid by the author to a correct reference of each term according to the field of application.
Finally, this book fulfills the intension of its author, to collect relevant terms with the correct pendant from a huge variety of sources and applications. It provides the user a foundation for correct terminology and communication for international contacts.
Der 2005 erstmalig erschienene und bewährte "Projektmanagement‐Kompass" wurde durch den auf diesem Gebiet erfahrenen Autor auf den neuesten Stand gebracht und zum 4. Mal neu aufgelegt. Den Lesern soll hiermit geholfen werden,"ihre Projekte strukturiert zu bearbeiten, überlegt zu handeln und ihr Vorhaben zielorientiert durch den Parcours der Überraschungen zu bewegen".
In 5 Hauptkapiteln führt das Buch nach einer Übersicht einem Kompass gleich vom Start über die Planung und Umsetzung zum Ende von Projekten.
Durch seine klare Struktur, die sich im vorgestellten PM‐Kompass wiederfinden lässt, wird dieses Buch seinem Anspruch, beim Projektmanagement den richtigen Weg zu weisen, gerecht.
