Characterization of two iron bullets from the royal ammunition factory of Eugi (Spain)
In this work, a comparative analysis of two iron bullets found in The Royal Ammunition Factory of Eugi in Navarra (Spain) was performed. Both bullets presented a spherical shape with a relatively good state of preservation, ... -
Comparative study of the metallurgical quality of primary and secondary AlSI10MnMg aluminium alloys
The use of secondary aluminium is increasingly being promoted in the automotive industry for environmental reasons. The purpose of this study was to demonstrate that it is possible to obtain a recycled AlSi10MnMg(Fe) ... -
A comprehensive study on hot corrosion resistance of NiCoCrAlYTa and NiCrAl thermal-sprayed coatings for CSP applications
The new generation of concentrated solar power (CSP) plants could be able to work at temperatures up 650 °C and carbonates molten salts are one of the main candidates to be used as thermal energy storage (TES) materials. ... -
Corrosion behavior in volcanic soils: in search of candidate materials for thermoelectric devices
Thermoelectric generators have emerged as an excellent solution for the energy supply of volcanic monitoring stations due to their compactness and continuous power generation. Nevertheless, in order to become a completely ... -
Effect of the temperature in the mechanical properties of austenite, ferrite and sigma phases of duplex stainless steels using hardness, microhardness and nanoindentation techniques
The aim of this work is to study the hardness of the ferrite, austenite and sigma phases of a UNS S32760 superduplex stainless steel submitted to different thermal treatments, thus leading to different percentages of the ... -
Estudio de la oxidación a elevada temperatura de ocho aleaciones en atmósferas de combustión de biomasa
La combustión de biomasa, especialmente de paja de cereal, genera un ambiente muy corrosivo, particularmente, cerca de los tubos sobrecalentadores. El cloro es el principal agente corrosivo en las plantas de biomasa. Este ... -
Functionalized electrospun fibers for the design of novel hydrophobic and anticorrosive surfaces
In this work, a novel coating was deposited on aluminum alloy samples by using a combination of electrospinning and chemical vapor deposition (CVD-silanization) techniques in order to create a functionalized film with an ... -
Hydrophobic and corrosion behavior of sol-gel hybrid coatings based on the combination of TiO2 NPs and fluorinated chains for aluminum alloys protection
In this work, layers of a sol-gel hybrid matrix doped with metal oxide nanoparticles (TiO2 NPs) have been deposited on flat samples of AA6061-T6 aluminum alloy using the dip-coating technique, with the aim of obtaining ... -
Influencia de bajas cantidades de fase sigma en las propiedades mecánicas y en la resistencia a corrosión localizada en tubos de acero inoxidable dúplex UNS S32760
Los aceros inoxidables dúplex (DSS de sus siglas en inglés: Duplex Stainless Steels), que presentan una microestructura mixta con un porcentaje similar de fases ferrita (α) y austenita (γ), son susceptibles a la formación ... -
Multifunctional protective PVC-ZnO nanocomposite coatings deposited on aluminum alloys by electrospinning
This paper reports the use of the electrospinning technique for the synthesis of nanocomposite micro/nanofibers by combining a polymeric precursor with hydrophobic behavior like polyvinyl chloride (PVC) with nanoparticles ... -
Relationship between microstructure and fracture types in a UNS S32205 duplex stainless steel
Duplex stainless steels are susceptible to the formation of sigma phase at high temperature which could potentially be responsible for catastrophic service failure of components. Thermal treatments were applied to duplex ... -
Revisión sobre la corrosión de tubos sobrecalentadores en plantas de biomasa
En el diseño de plantas de biomasa es muy importante tener en cuenta la temperatura del vapor para no tener problemas de corrosión. Esto, es debido al alto contenido de potasio y cloro que tienen la mayoría de los ... -
Revisión y estado del arte de la corrosividad del etanol y sus mezclas con gasolina
Actualmente, el etanol se presenta como una fuente importante de combustible renovable para el sector de la automoción. Se sabe que los carburantes tradicionales, como la gasolina, no han causado problemas de corrosión, ... -
Study of corrosion in a biomass boiler
Biomass plants, apart from producing energy, help to reduce CO2(g) emissions. One of the biggest problems for their development is superheater corrosion due to fuel corrosivity, especially of the straw. This limits both ... -
Study of effect of nickel content on tribocorrosion behaviour of nickel-aluminium-bronzes (NABs)
The simultaneous existence of mechanical erosion and electrochemical corrosion is a common scenario for engineering alloys used in marine environments, such as pump impellers and valves. Nickel–aluminium–bronzes (NABs) are ... -
Study of the degradation of heat exchanger materials in the acidic environment of Teide National Park
Supplying power to volcanic monitoring stations constitutes a challenge due to both the access difficulties and the acidic environment associated with volcanoes. ELECTROVOLCAN project is developing thermoelectric generators ... -
Using the multi-response method with desirability functions to optimize the zinc electroplating of steel screws
Zinc electroplating is a coating process controlled by several input process parameters. However, the commonly used input parameters for setting the process of zinc deposition are current density, temperature of the coating ...
