Abstract | This paper investigates the in situ tensile cracks propagating behavior of composite coatings on the aluminized steel generated using the plasma electrolytic oxidation (PEO) technique. Cross-sectional micrographs and elemental compositions were investigated by scanning electron microscopy (SEM) equipped with energy dispersive spectroscopy (EDS). The composite coatings were shown to consist of Fe-Al, Al and Al(2)O(3) layers. The cracks propagating behavior was observed in real-time in situ SEM tensile test. In tensile process, the cracks were temporarily stopped when cracks propagated from Fe-Al layer to Al layer. The critical crack opening displacement delta(c) was introduced to quantitatively describe the resistance of the Al layer. There was a functional relation among the thickness ratio t(Al)/t(Al2O3), the delta(c) of composite coatings and tensile cracks' spacing. The delta(c) increased with the increasing of the thickness ratio (t(Al)/t(Al2O3)). The high delta(c) value means high fracture resistance. Therefore, a control of the thickness ratio t(Al)/t(Al2O3) was concerned as a key to improve the toughness and strength of the aluminized steel. (C) 2010 Elsevier B.V. All rights reserved. |
