On the influence of silicon on the growth of the alloy layer during hot dip aluminizing

The reactions between a low alloyed steel and a pure as well as a 2% Si containing Al melt were studied at 780 and 792 deg C, respectively. The velocity of the Fe enrichment was the same for both cases, whereas the alloy layer growth was much faster in the case of the pure Al melt. After hot dip alu...

Description
Summary:The reactions between a low alloyed steel and a pure as well as a 2% Si containing Al melt were studied at 780 and 792 deg C, respectively. The velocity of the Fe enrichment was the same for both cases, whereas the alloy layer growth was much faster in the case of the pure Al melt. After hot dip aluminizing in the 2% Si containing Al melt, Si was found to be incorporated in the alloy layer. From that it is clear that Si acts on the solid state side, when reducing the alloy layer thickness during hot dip aluminizing. 14 ref.--AA
