Correlation between the wear resistance, and the scratch resistance, for nanocomposite coatings
(Elsevier, 2011)
The nanoscratch test, used in this study, quantitatively characterizes the scratch behaviour of coatings. Some of the obtained parameters are plastic and elastic deformation, critical load to start the scratch, chipping ...
Hardness and Young's modulus distributions in atmospheric plasmas prayed WC–Co coatings using nanoindentation
(Elsevier, 2011-05-25)
A statistical indentation analysis of WC–Co coatings obtained by atmospheric plasma spray (APS) with two secondary plasma gases, H2 and He, was investigated using an instrumented indentation technique with the aim of ...
Quantifying road dust resuspension in urban environment by Multilinear Engine: A comparison with PMF2
(Elsevier, 2009)
Atmospheric PM pollution from traffic comprises not only direct emissions but also non-exhaust emissions because resuspension of road dust that can produce high human exposure to heavy metals, metalloids, and mineral matter. ...
Simple estimates of vehicle-induced resuspension rates
(Elsevier, 2011-10)
Road dust emissions are considered to be a major source of airborne particulate matter (PM). This is particularly true for industrial environments, where there are high resuspensionrates of deposited dust. The calculation ...
Electrokinetic and rheological properties of highly concentrated kaolin dispersions: Influence of particle volume fraction and dispersant concentration
(Elsevier, 2010)
An industrial kaolin was selected and characterised. Different dispersions were prepared with solids volume fractions between φ{symbol} = 0.20 and φ{symbol} = 0.47 in the presence of sodium silicate (between X<sub>s</sub> ...
Non-destructive measurement of bulk density distribution in large-sized ceramic tiles
(Elsevier, 2010)
An apparatus has been designed, built, and patented that is able, non-destructively, to determine bulk density distribution in large-sized ceramic tiles. The proposed method, based on the X-ray absorption technique, provides ...
A procedure to evaluate the resistance to biological colonization as a characteristic for product quality of ceramic roofing tiles
(Elsevier, 2011)
Ceramic roofing tiles suffer deterioration through time due to environmental exposure. Biological colonization affects the appearance and integrity of building materials, such as roofing tiles. The resistance to biocolonization ...
Use of coatings to minimise acid emissions during ceramic tile firing.
(© 2011 Elsevier, 2011-06)
The manufacture of traditional ceramic products (ceramic tiles, roof tiles, and bricks) is often associated with the emission of F, Cl, and S compounds during the firing stage. According to the literature, fluorine emissions ...
Microstructure and photocatalytic activity of suspension plasma sprayed TiO2 coatings on steel and glass substrates
(Elsevier, 2011-10-25)
In this study, TiO2 coatings were deposited by suspension plasma spraying (SPS) from a commercial TiO2 nanoparticle suspension on two different substrates: a standard stainless steel and a Pyrex glass. Coatings were sprayed ...
Study of the rheological behaviour of monomodal quartz particle beds under stress: a model for the shear yield functions of powders
(Elsevier, 2011-09-15)
A model is proposed that describes the yield locus of powders. The model is based on the adhesive contact of elastic spheres theory developed by Johnson, Kendall, and Roberts (JKR model). The proposed model improves the ...
