Influence of uniaxial deformation on the corrosion performance of pre-coated packaging steel

A bulk and localised electrochemical assessment of epoxy-phenolic coating degradation

“…Under-film water accumulation can occur significantly at substrate discontinuities produced during the electrodeposition and the coil rolling process [51,52]. Grain boundaries impurities, micro-cracks, metal oxide pores and Lüders bands formations are all reasons for insufficient polymer bonding [53,54]. The presence of Cl -at such regions can cause metal oxide dissolution [55].…”

Influence of uniaxial deformation on surface morphology and corrosion performance of chromium-based coatings for packaging steel

“…J o u r n a l P r e -p r o o f coating steels to resist corrosion initiation [9][10][11][12][13][14]. A corrosion mechanism associated with this coating matrix is cathodic disbondment.…”

“…This corrosive response to a defect in the polymer coating will determine how long the contents of a can remain preserved [9]. Deformation has been shown to reduce the corrosion performance of ECCS [9,10]. Scanning Kelvin probe (SKP) investigations have been investigated for Cr3 + based electrolyte coatings and ECCS [1,2].…”

Electrodeposition of mixed chromium metal-carbide-oxide coatings from a trivalent chromium-formate electrolyte without a buffering agent

“…Chromium coatings are widely used for many different applications, including Electrolytic Chromium Coated Steel (ECCS) for packaging applications [1][2][3]. ECCS consists of a thin gauge low carbon steel substrate with a very thin coating comprising a base layer of chromium metal (50-150 mg m -2 ) and a top layer of chromium oxide (7-35 mg m -2 ).…”
