KORNIENKO, E.; OSSENBRINK, R.  e  MICHAILOV, V.. Evaluation of corrosion behaviour of organic-coated structured sheet metals. Corros. Prot. Mater. [online]. 2013, vol.32, n.3, pp.82-86. ISSN 2182-6587.

In the present paper the corrosion behaviour of organic-coated structured sheet metals was analysed. These materials are innovative and with three-dimensional geometry. The major advantage of this sheet metal is a higher stiffness in comparison with a smooth sheet. The material was coated by the industrial process of cathodic electrodeposition. The aim of this study is to evaluate the effect of sheet geometry on the corrosion behaviour and the influence of the structuring process on the corrosion properties. For comparison purposes the corrosion resistance of coated smooth sheet metals was determined. The results show that the sheet geometry has no noticeable effect on the corrosion behaviour. The deformation due to the structuring process affects the coating system strongly.
