Abstract: In this research plasma nitriding of pure aluminium and effect of iron elemental alloy on the formation and growth of aluminium nitride was investigated. Also corrosion properties of formed AlN were investigated. After preparation, the samples were plasma nitrided at 550oC, for 6, 9 and 12 h and a gas mixture of 25%H2-75%N2. The microstructure and phases analysis were investigated usi...

Contamination of Pansky Pond, in March 2013, with 119 mg/l aluminium, and 87 mg/l iron by acidic (pH 3.17) inflow from a nearby quarry caused fish die-off, while exhibiting symptoms of suffocation. Transformation of soluble forms of aluminium and iron into insoluble forms occurred on fish gill where the content of aluminium and iron was 100-fold and 12-fold, respectively, that found in control ...

After initial commissioning of the charge state breeder for radioactive ions at the TRIUMF/ISAC facility further tests on the performance of the system have been done., One of the major problems found was the high background of stable ions from the ECR source. The main source of those is the residual gas and sputtered material from the plasma chamber wall and from the surrounding electrodes. Al...

Impurities enter the electrolyte mainly from the consumable carbon anode and aluminium oxide. Important impurity elements are iron, silicon, phosphorus and sulfur. Metallic impurities such as iron and silicon tend to codeposit at the cathode, while dissolved phosphorus and sulfur species also affect the current efficiency for aluminium production. In modern industrial cells more impurities end ...

Work-related asthma has been documented in workers employed in the primary aluminium industry and in the production of aluminium salts. The role of aluminium in the development of occupational asthma has, however, never been convincingly substantiated. We investigated a subject who experienced asthmatic reactions related to manual metal arc welding on aluminium. Challenge exposure to aluminium ...

electrochemically generated iron can remove most contaminants present in water and wast water, by precipitation, adsorption, electrostatic interaction, and complex formation (generally called electrocoagulation-ec). in the present paper, pretreatment of brackish water having high total hardness (th), alkalinity (a),  and cl¯ ions, is studied by application of a dc-electrical current ot the iron...

In this study, removal of methylene blue by electro-coagulation method using aluminum and iron electrodes was investigated. The influence of the operating parameters such as contact time, current density, anode type, inter-electrodes distance, initial and final pH and energy consumption rate was determined. Dye removal was increased with increases in solution pH, current density and c...

OBJECTIVE To evaluate acceptability, compliance and attitude towards the use of iron pots compared with aluminium pots, for cooking in a community that traditionally did not use iron pots. DESIGN Randomised trial. SETTING Two rural Malawian villages. SUBJECTS Fifty-two households received iron pots and 61 aluminium pots. RESULTS Pot characteristics were assessed by a questionnaire after...

In acid soils, soluble inorganic phosphorus is fixed by aluminium and iron. To overcome this problem, acid soils are limed to fix aluminium and iron but this practice is not economical. The practice is also not environmentally friendly. This study was conducted to improve phosphorus availability using organic amendments (biochar and compost produced from chicken litter and pineapple leaves, res...
