Corrosion Mechanism of Press-Hardened Steel with Aluminum-Silicon Coating in Controlled Atmospheric Conditions
Popis výsledku v původním jazyce
The effect of various atmospheric parameters on the corrosion mechanism ofpress-hardened steel (PHS) coated with Al-Si (AS) was studied. Quantitative models ofthe composition of soluble and stable corrosion products were developed. A high chlorideconcentration led to a localized corrosion due to the presence of cracks in the coating.Increased corrosion resistance of silicon-rich Al8Fe2Si and AlFe at the expense of the Al5Fe2phase with low silicon content was shown. Under low-chloride-deposition conditions,the coating exhibited good corrosion resistance and provided sufficient protection to theunderlying steel. The formation of more local anodes and cathodes under conditions oflower relative humidity led to a reduction in the depth of corrosion pits in the steel substrate.Constant high relative humidity and sulphate deposits on the surface were critical for theacceleration of steel corrosion in coating cracks.
