Aluminium Coating on Iron

Performance of Tannin/Glycerol-Chromate Hybrid Conversion Coating on Aluminium

A smart hybrid conversion coating has been developed. Modifications of coating solutions with poly-hydroxyl organic materials to reduce the usual mud cracking pattern characteristics of chromate conversion coatings (CCCs) and improve its ability to release inhibitors to corroding sites have been achieved. The smart functionalised chromate conversion coating (SFCCC), developed on aluminium subst...

Sustainable Aluminium and Iron Production

Aluminium and iron/steel are truly sustainable materials. As a result the global metallurgical industry strives to produce products, which contribute to the global effort by reducing resource use, recycling and reusing materials where possible, and to help create the economic and supply frameworks needed to do this. Aluminium is a material that is infinitely recyclable and remarkably plentiful....

Oxidation Proof Silicate Surface Coating On Iron Sulfides

THE RELATIONSHIP BETWEEN ALUMINIUM TOXICITY AND IRON METABOLISM IN RATS

The relationship between aluminium toxicity and iron metabolism was studied. Male rats were exposed to aluminium by daily intraperitoneal injection of 40pmolelkg body weight. After 45 days, aluminium intoxified rats had a significant loweredserum ferritin (55%), iron (42%), TIBC (25%) and hemoglobin(31%). At thesame time the serum ceruloplasmin level was elevated by 60%. This result shows t...

Microstructure and interfaces of a reaction coating on aluminium alloys by laser processing

This paper reports an approach to coat a ceramic layer on aluminium alloys by means of chemical reaction. The reaction product of Al,0, layer of 100 pm in thickness has been formed using a powder mixture of silicon oxide and aluminium by laser processing. It turns out that the large amount of heat from the exothermic reaction has a predominate effects on the formation of the oxide layer. Furthe...
