Abstract: Red rust staining of Al/Zn coated steel strip in “acid rain” or “polluted” environments can be minimised by forming the coating as an Al—Zn—Si—Mg alloy coating with an OT:SDAS ratio greater than a value of 0.5:1, where OT is the overlay thickness on a surface of the strip and SDAS is the measure of the secondary dendrite arm spacing for the Al-rich alpha phase dendrites in the coating. Red rust staining in “acid rain” or “polluted” environments and corrosion at cut edges in marine environments can be minimised in Al—Zn—Si—Mg alloy coatings on steel strip by selection of the composition (principally Mg and Si) and solidification control (principally by cooling rate) and forming Mg2Si phase particles of a particular morphology in interdendritic channels.

Abstract: The present disclosure is directed to methods for preparing nanoparticle monolayers on a sub-phase by controlling the spreading rate of the nanoparticles. The nanoparticles are first prepared in a nanoparticle solution at a predetermined concentration with a solvent. The sub-phase solution is prepared to have a density and viscosity compatible with the desired spreading rate. Additives, such as glycerol, are used to alter the density of the sub-phase solution. A volume of nanoparticle solution is deposited on the surface of the sub-phase solution and allowed to spread in a controlled manner on the unconstrained surface, forming a uniform nanoparticle monolayer. A substrate is then placed in contact with the nanoparticle monolayer to form a uniform nanoparticle coating on the surface of the substrate.
