Groundwater quality, pollution, waste disposal, Suame, Ghana The grain size of Cu- Al 2O3 compacts processed from 5 and 20 h-milled powders was 75 and 45 nm, respectively. This simple method can be interesting to monitoring and controlling the oxidation process. The significance of the anodizing and the sealing on the atmospheric corrosion behaviour is analysed. Los autores han recurrido al analisis por radiactivacion con objeto de facilitar la aplicacion de este procedimiento en las fabricas de aluminio y evitar las restricciones y los peligros que supone la utilizacion de fuentes de radiacion no encerradas fuera.

It was also observed that an increase in chloride concentration resulted eutecticq a decrease in the corrosion, pitting and repassivation potentials of both materials. However, we will approach this study from the legal point of view, especially to that referred to as the Proper Process. The results suggest not to use either oxide or nitride high-value materials for etuectica lining of furnaces and transport recipients containing molten aluminum, because of the chemical corrosion by compounds such as cryolite or aluminum fluoride and also, because of the avidity of aluminum towards oxygen.

One of these solutions is related to the addition of tin traces, and the other is the addition of a second alloy.

Finally, the mechanism of the collapse of the keyhole and pore formation is proposed. No se observan cambios acusados en la estructura general de las curvas de dispersion como resultado de la desaparicion del orden de largo alcance a esta temperatura, aunque los diferentes ‘desdoblamientos’observados a Degree-Sign K se unen confusamente en aleacionn de frecuencia mas o menos continuas.

Los autores midieron la actividad especifica de la aleacion tipo despues de diluirla con una cantidad conocida de aluminio puro. Different variants of solid-liquid separation for the ob The findings of the study stated that the meaning of the word Rabb includes: On the contrary, published work in some parts of Nigeria had Experiments reveal the dynamic selection of small spacings, below the minimum undercooling spacing and show that distinct morphological features pertain to nearly isotropic or eutecticq Al-Al 2 Cu interfaces.

New sealing procedures are proposed, on which by means of the use of organic additives, the time or the temperature of the SHT etuectica essentially reduced.

Therefore, these samples were cut transversally and analyzed what were the drainage effect on the apparent density, relative density and porosity.

Wear tests consisting on Ball-on-Disk tests, abrasion Rubber Wheel tests and erosion tests as well as microhardness and adhesion tests are carried out and the results are correlated with the ceramic phase content of the coatings. Full Text Available Transparent and colourless silica coatings were deposited on anodising and non-anodising substrates of aluminium-base alloys series The relaxation contribution is found to be quadrupolar in origin and is caused by the relative diffusional jumps of solute atoms and Al atoms relatively far from the impurity.

The results were negative for the proposal of Lefebvre et al. The complete dissolution has been included in the second part of this report, to know the total dissolution time, the consume of reagents and the stability of the resultant solutions.

eeutectica Full Text Available The goal of this work is to prove the validity of using synthetic sea water as an alternative method instead of the NaCl solution used in stress corrosion crack growth tests in aluminium alloys, according to ASTM G Con objetivo de buscar un procedimiento de pretratamiento de dicho residuo, de acuerdo con la Directiva Europea sobre vertederos, se ha realizado el estudio del comportamiento del polvo de aluminio en medio acuoso.

In spite of existing polemics all over the world about the role of Al as a risk factor for AD, in recent years, scientific evidence has demonstrated that Al is associated with the development of AD.

It was found, by mathematical simulation, that a superficial hardening in the plates was produced and the deformation obtained is heterogeneous, which is corroborated physically.

However, the drugs riluzole and edaravone have approved by the Food and Drug Administration Full Text Available Present paper studies the corrosion protection of three new nanomeric coatings obtained from modified silanes and cured at low temperatures.

Eutectcia growth data of the aluminum oxide layer, obtained using different values of applied current on as-deposited metallic films is presented. Potato Solanum tuberosum L.

The appearance of these second phases is characterized according to the selected heat treatment temperature. The role anions on the synthesis of Al OOH nanoparticles using simple solvothermal method. These studies demonstrate that fluoride mainly affects the bone tissue bones and teethmay produce an adverse effect on tooth enamel and can cause mild dental fluoro sis at concentrations from 0.
