Comparative corrosion behaviour of 55Aluminium–zinc alloy and zinc hot-dip coatings deposited on low carbon steel substrates

The Role of Texture and Microstructure in Optimizing the Corrosion Behaviour of Zinc Hot-dip Coated Steel Sheets

“…In this way, a dynamic and quick Zn consumer process leads to catastrophic results after short exposure periods, at least, from the anticorrosive point of view. 22) Also, other researchers have ascribed the initiation of corrosion to a mechanism of stress corrosion and have discussed that in the case of hotdip galvanizing, when the outer phase of the Zn diffusion coating is delta, due to the mismatch between the thermal © 2008 ISIJ expansion coefficients of the Fe-Zn phases of the coating and the iron substrate, development of tensile residual stresses upon cooling and exposing the coated object to the air can be happened. 23) These stresses are relieved through the formation of cracks inside the Zn coating.…”

Effect of Surface Conditions and Relative Humidity on Hydrogen Permeation Behavior of Zinc Coated Steels during Wet and Dry Corrosion

“…Therefore, hydrogen embrittlement has attracted much attention recently. [6][7][8][9][10][11][12][13][14][15][16] Matano et al 8) reported an evaluation of deformation microstructures and associated lattice defects in SUS 304 and SUS 316 L steels by positron lifetime measurements detecting vacancy-type defects created during tensile straining. Nagao et al 10) investigated the mechanism of fracture surface morphology changes at intergranular and quasi-cleavage in a hydrogen embrittled lath martensitic steel.…”

Development of an Area-selective Technique for Electrochemical Hydrogen Detection with Laser Local Activation

“…Hydrogen embrittlement has, therefore, attracted much attention recently. [3][4][5][6][7][8][9][10][11][12][13][14] Several techniques such as thermal desorption spectroscopy, 15) hydrogen microprint technique, 16) silver decoration method, 17) electrochemical hydrogen detection, 18,19) and tritium autoradiography 20) have been applied to measure or visualize hydrogen in the metals. The hydrogen entry efficiency (ratio of hydrogen permeation current and hydrogen generation current) and hydrogen diffusion coefficient, D H , may depend on grain boundary and segregation at the entry surface.…”
