Electroless nickel–boron (ENB) coatings from borohydride-reduced baths have received wide acceptance thanks to their excellent hardness and superior wear resistance. Therefore, they have been considered as an alternative to hard chrome. However...
Layered double hydroxide (LDHs) coatings were developed for the corrosion protection of AZ31 Mg alloy. AZ31 is widely used in the transport industry due to its low mass density and good mechanical properties. LDH coatings were fabricated under co-pre...
In Finland, the repositories for low- and intermediate-level waste (LLW and ILW) are situated in three different geographical locations in deep granite bedrock, where waste containers can be subjected to anoxic groundwater containing microbes. The co...
Organic corrosion inhibitors embedded in coatings play a crucial role in substituting for traditional anti-corrosion pigments, which can cause acute toxicity problems to human health and the environment [...]
Thermal energy storage (TES) is required when using energy sources that are intermittent in order to fill the gap between energy supply and energy demand. Latent heat storage systems are based on phase change materials (PCM) such as salt hydrates, wh...
Prestressed reinforced concrete beams are widely used in industrial and commercial buildings, which are commonly exposed to aggressive environments and damaged by corrosion. This precast construction technique has also been used for the last 50 years...
Post-tensioned (PT) construction incorporating bonded tendons with cementitious grouts has been used for highway bridges. The tendon duct and the encapsulating grout materials provide barrier corrosion protection for the embedded high-strength steel...
In contrast to other additive manufacturing methods such as Wire Arc Additive Manufacturing or Laser Metal Deposition, the cold spray system designed by SPEE3D allows for structures to be printed at much lower temperatures. As a result, structures pr...
Magnesium alloys are actively researched for biodegradable implants in order to avoid an implant-removal surgery after the healing process. However, the high degradation rate of Mg leads to hydrogen evolution and may increase the pH of the environmen...
Recently, Fe-based amorphous coatings synthesized by different thermal spraying methods have been investigated as a potential candidate for long-term surface protection of various structures due to their outstanding wear and corrosion resistance. Def...
The corrosion of steel bars in concrete is a dangerous and extremely costly problem that causes losses of serviceability and structural capacity in buildings and bridges. Once the depassivation occurs, because of concrete carbonation or chloride atta...
The corrosion of steel reinforcement is the most significant factor responsible for the premature deterioration of the durability and seismic resistance of reinforced concrete structures. As such, the main objective of the present study is the invest...
Magnesium is very light metal which possesses many useful properties, such as a high strength to weight ratio and good electrical and thermal conductivity. Magnesium and its alloys can be used in implant surgery as biodegradable materials. Taking int...
According to currently enforced Eurocode 2 for the design of reinforced concrete structures, it is essential to protect steel reinforcements from corrosion and concrete from degradation under aggressive environmental conditions such as marine, urban,...
Metal fatigue management is generally well understood as reflected in the Aircraft Structural Integrity Management Plans, which, in some cases, consider environmental degradation prevention; however, limited provisions beyond find and fix exist for c...
Zinc phosphate coatings are commonly used to protect high-strength steel rods and improve the corrosion protection ability. The temperature and the pH of the phosphating bath are important parameters that affect to the film’s appearance, porosi...
In this paper, the Shape Memory Steel (SMS), a new kind of ferrous SMA of the Mn family and complemented with Cr additions, is introduced as a very interesting smart material, able to be used in fitting and reshaping applications, and with the potent...
Innovative 3D metal additive manufacturing (AM) techniques are revolutionizing the biomedical industry, since they enable the production of porous structures and patient-customized parts of biomedical-grade materials, such as Ti alloys. Surface treat...
At present, the cement industry still constitutes an important pollutant in the industrial sector. As such, strategies to reduce its environmental impact are a popular research topic. One of these strategies consists of partially replacing clinker wi...
Traditional additive manufacturing (AM) technologies tend to focus on powder bed fusion (PBF) methods, such as SLM (selective laser melting) and EBM (electron beam melting), that are attractive for the rapid production of complex components. However,...
This paper comprises of hydrogen embrittlement phenomena in material, factors responsible for the hydrogen embrittlement and non-destructive methods to evaluate the internal defect in machines or components when working in hydrogen atmosphere. Hydrog...
Cerium salts in the form of ammonium cerium(IV) nitrate and cerium(III) nitrate hexahydrate are widely used as corrosion inhibitors due to their ability to provide active protection against corrosion. When incorporated into polymeric, ceramic or hybr...
The corrosion of iron in an acidic medium similar to acid rainwater (pH = 3.6) at various rotation speeds was investigated. The investigation included the inhibiting effect of two new green formulations containing oils extracted from the seeds of Jat...
In the industrial field, manufacturing time is one of the most important factors affecting production costs. Structural adhesives require long curing times (i.e., 3–4 weeks) before the joined components can be safely employed. The aim of the present...
Some commercial dental implants contain aluminum, which represents a potential risk to health, since aluminum is associated with neurodegenerative diseases such as Alzheimer’s disease. Therefore, control of the chemical composition as well as t...
Nowadays, the durability of reinforced concrete (RC) elements affected by corrosion has become a worldwide research topic, especially after some catastrophic failures that have involved corroded structures and infrastructures. One of the main purpose...
Biobased polymers and composites have gained increased global attention due to their abundance, renewability, and biodegradability. Natural fillers such as cellulose-based fillers improve the mechanical properties of biopolymers, extending their appl...
Complex concentrated alloys (CCAs) are new types of materials, where the equimolar rule proposed by high entropy alloys (HEAs) is modified in relation to the potential of the obtained structures. CCAs expend the compositional space of the conventiona...
Titanium Grade 4 (G4) is the most commonly used material for dental implants due to its excellent biocompatibility and mechanical properties. However, titanium implants require a rough surface that can increase the biomechanical potential of implant–...
Biodegradable magnesium alloys are promising materials for application in medicine. The corrosion rate and type of corrosion are among the most important properties for this kind of materials. The fine-grained biodegradable alloys AZ31 (hot-rolled) a...
Stainless steel is a material manufactured for its high corrosive resistance and is the first choice of material in a range of applications. Microbial-induced corrosion can cause significant damage to metals and is responsible for approximately 20% o...
Evaluation of NiTi alloy corrosion behavior in conditions that exist in the oral cavity still remains a great characterization challenge. Such characterization is commonly simplified by avoiding the use of non-accelerated corrosion tests. Accordingly...
