Passivation and Chemical Conversion Combined Multi-Elements Coating on Low Sn-Coated Steel for Corrosion Protection

In this work, the tinplate with 0.5 g·m −2 tin coating mass was prepared in order to improve the economic benefit for food packaging field. We studied this low Sn-coated steel surface state and developed a process combined Mo-Mn-Al-P coating based on its special structure. By Taguchi techniques opti...

Description
Summary:In this work, the tinplate with 0.5 g·m −2 tin coating mass was prepared in order to improve the economic benefit for food packaging field. We studied this low Sn-coated steel surface state and developed a process combined Mo-Mn-Al-P coating based on its special structure. By Taguchi techniques optimization, this chromium-free multi-elements coating has excellent corrosion resistance and adhesion with organic coatings, would be a hopefully replacing traditional chromate passivation treatment on tinplate with low tin coating mass.
