The growing rate and the type of corrosion products of aluminium alloy AA 5052 in deionized water at temperature up to 3000C
Description
The process of corrosion concerning the aluminum alloy AA5052 in deionized water at temperatures of 400C, 800C, 900C, 1400C, 2000C and 2800C is studied. The following methods are used: periodic weighting of the test samples; analysis by neutronic activation of the corrosion products dissolved in water; thermogravimetric and thermodiferential analysis; analysis through X-ray diffraction and from metalografic observations of the crystals produced in the corrosion process; an optical microscope using polarized and normal light and a scanning electronic microscope. The activation energies are calculated for the corrosion film formation, and for the dissolution of the corrosion products in the deionized water. (ARHC)

Estuda-se o processo de corrosao da liga de aluminio AA5052 isotermicamente nas temperaturas de 400C, 600C, 800C, 900C, 1400C, 2000C e 2800C, em agua deionizada. Os metodos utilizados para este estudo sao, atraves de pesagens periodicas dos corpos-de-prova, de analises por ativacao neutronica dos produtos da corrosao dissolvidos na agua, de analises termogravimetrica e termodiferential, de analises por difracao de raios-X e de observacoes metalograficas dos cristais produzidos no processo da corrosao, com o auxilio de microscopia otica com luz polarizada e microscopia eletronica de varredura. Calculam-se as energias de ativacao para a corrosao aquosa da liga de aluminio e para a dissolucao dos produtos de corrosao em agua deionizada. (ARHC)Files
