A methodology for characterizing the electrochemical stability of DLC coated interlayers and interfaces

Stefano Mischler, Emilija Ilic

DLC coatings are often deposited on Si and Cr based adhesion-promoting interlayers to mitigate stress at the DLC/substrate interface. Interlayers reduce the likelihood of mechanical coating delamination. However, their chemical stability at miniature DLC c ...

Application of Time Series Methods on Long-Term Structural Monitoring Data for Fatigue Analysis

Eugen Brühwiler, Bartlomiej Wojciech Sawicki

Structural health monitoring (SHM) can be employed to reduce uncertainties in different aspects of structural analysis such as: load modeling, crack development, corrosion rates, etc. Fatigue is one of the main degradation processes of structures that caus ...

H2-fuelled microbial metabolism in Opalinus Clay

Rizlan Bernier-Latmani, Luca Loreggian, Niels Burzan, Aislinn Ann Boylan, Carla Perez Mon

In Switzerland, the Opalinus Clay formation is considered the most likely host rock for a deep geological repository for nuclear waste. In deep geological repositories, H2 is expected to be the most abundant gas formed from the degradation of waste and fro ...

Degradation of modular hip joint implants : a corrosion and tribocorrosion approach

Angela Bermudez Castañeda

Total hip joint arthroplasty is a medical procedure to replace a natural failed joint by an artificial joint to improve the quality of life of the patient. In spite of its broad success, there is a concern about the relation between the presence of modular ...

Corrosion mechanisms and durability models for historical tinplate food cans

Fabio Cova Caiazzo

Since the early of the 19th century, canning is one the most efficient ways to preserve foods. Tinplated steel has been used since the beginning for this purpose and it is still one of the most used materials for cans production because it combines the goo ...

Numerical simulation of the probability of corrosion initiation of RC elements made of reinforcing steel with improved corrosion performance

Eugen Brühwiler, David Conciatori

Steel reinforcing bars in concrete are protected from corrosion by a thin oxide film that is created on the steel surface in the highly alkaline environment of the concrete. Corrosion process begins once this oxide film is destroyed, for example, by chlori ...

Nanocrystalline Boron-Doped Diamond as a Corrosion-Resistant Anode for Water Oxidation via Si Photoelectrodes

Kevin Sivula, Jun Ho Yum, Ladislav Kavan, Florian Le Formal

Due to its high sensitivity to corrosion, the use of Si in direct photoelectrochemical (PEC) water-splitting systems that convert solar energy into chemical fuels has been greatly limited. Therefore, the development of low-cost materials resistant to corro ...

Long-term monitoring of existing wind turbine towers and fatigue performance of UHPFRC under compressive stresses

Christophe Thierry Loraux

An increasing number of onshore wind turbines in Europe will reach the end of their relatively short service duration, currently limited to 20 years by the design codes and many owners already wish to extend the service duration of their turbines. Recently ...
