摘要：

Calcium carbonate scale deposition from its sludge on aluminium metal surface was studied and compared with copper. Ethylenediamminetetraacetic acid (EDTA) was used as a scale inhibitor and the experiments were carried out at 60 and 100 °C. The samples were characterised by XRD, FTIR and SEM techniques. The study revealed that the deposition of scale on the substrate is not only influenced by the chelating agent and temperature but also depends on the type of metal. This phenomenon of metal-induced polymorphic stabilisation and morphological changes has so far been not reported and the possible mechanism is discussed. © 2016 Informa UK Limited, trading as Taylor & Francis Group.
