THE CORROSION-ELECTROCHEMICAL BEHAVIOR OF ALUMINIUM IN MELTING OF CARBONATES OF THE ALKALI METALS, CONTAINING THE ADDITIVES OF SUBSTANCES OF THE DIFFERENT CHEMICAL NATURE

Investigated has been the interaction of aluminium, grade A99 with melt of carbonates of lithium, natrium, kalium (40:30:30% mol), containing the activators and passivators of corrosion. Shown have been the variations of the corrosion properties, electrochemical behavior of aluminium in the presence of the additives. The composition, structure and morphology of the layers on aluminium have been investigated. The mathematical evaluation of the different aspects of initiation of the corrosion affections have been made. The kinetics of the local corrosion has been investigated. The laws in the variation of the character and the mechanism of corrosion have been established, the classification of the additives by its action on the corrosion process on activators and passivators has been performedAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
