Possibilities of Affecting the Corrosion-Inhibition Efficiency of the Coatings by Means of the Zinc Powder Particle Sizes and Shapes

摘要

The paper deals with morphology and physicochemical aspects of zinc powder concerning the properties of coatings. The sizes or, sooner, the size zinc powder particle distribution manifest themselves especially in the mode of arrangement and affecting the electrochemical mechanism of action in the coating. The lamellar and isometric particle shapes affect by the pigmentation mode and height especially the barrier action and physicomechanical properties of the coating.
