Tribocorrosion of a CoCrMo alloy in sulfuric acid - Glycerol mixtures

This work reports on the tribocorrosion properties of a CoCrMo alloy sliding under imposed passive potential against alumina in sulfuric acid-glycerol mixtures exhibiting different viscosities and thus, in principle, lubrication properties. As expected, we ...

Understanding the carbonation of concrete with supplementary cementitious materials: a critical review by RILEM TC 281-CCC

Karen Scrivener, Barbara Lothenbach

Blended cements, where Portland cement clinker is partially replaced by supplementary cementitious materials (SCMs), provide the most feasible route for reducing carbon dioxide emissions associated with concrete production. However, lowering the clinker co ...

Heinz Isler’s twin shell roof in Deitingen – preservation of a ‘timeless wing beat’

Eugen Brühwiler

The Swiss shell pioneer Heinz Isler (1926–2009) fundamentally challenged established shell design methods by introducing original methods of form finding based on gravity. He realised elegant and pure shell forms in reinforced concrete, incarnating the per ...

Corrosion Mechanisms of Diamond-like Carbon Coated Interlayers & Interfaces

Emilija Ilic

Diamond-like carbon (DLC) coatings can improve the wear resistance of articulating implants. However despite successful in-vitro testing, some DLC coated joint replacements had to be revised prematurely, mainly due to coating delamination induced by corros ...

'Green' Cr(iii)-glycine electrolyte for the production of FeCrNi coatings: electrodeposition mechanisms and role of by-products in terms of coating composition and microstructure

Stefano Mischler, Johann Michler, Enrico Bertero

The electrodeposition of stainless steel-like FeCrNi alloys for miniaturised devices is appealing as it would allow combining excellent material properties (e.g. corrosion resistance, hardness, biocompatibility) at low-cost. However, conventional baths oft ...

Tribological response of multilayered gold nickel coating deposited on fine turned surfaces

Stefano Mischler

Gold coating are widely used in industry due to their corrosion resistance, electrical conductivity and low contact resistance. However, friction and wear can limit their functionality and lifetime. This study addresses the degradation of a commercial fine ...

The corrosion rate and microstructure of Portland cement and calcium aluminate cement-based concrete mixtures in outfall sewers: A comparative study

Karen Scrivener

This paper presents a comparative study on the corrosion rate and microstructural characteristics of Portland cement (PC) and calcium aluminate cement (CAC)-based concrete mixtures subjected to microbially-induced sulphuric acid (biogenic H2SO4) attack for ...

Silicon Corrosion in Neutral Media: The Influence of Confined Geometries and Crevice Corrosion in Simulated Physiological Solutions

Stefano Mischler, Patrik Schmutz, Roland Hauert, Emilija Ilic

Silicon (Si) based implantable components are widely used to restore functionalities in the human body. However, there have been reported instances of Si corroding after only a few years of implantation. A key parameter often overlooked when assessing Si s ...

On-Site Purification of Copper-Contaminated Vanadium Electrolytes by using a Vanadium Redox Flow Battery

Hubert Girault, Heron Vrubel, Alberto Battistel, Christopher Raymond Dennison, Danick Reynard

Corrosion of carbon-based electrodes and bipolar plates is a major hurdle and can be a cause of failure in commercial vanadium redox flow batteries (VRFBs). Carbon corrosion was found to occur in a commercial VRFB (10 kW/40 kWh), whereby cracks through bip ...
