Abstract

The surface morphology of aluminum-silicon coated press hardening steel with different heating time was studied by scanning electron microscopy, and the AS150 and AS60 coatings were also compared. The results show that the dendrite phase can be formed when AS150 is heated for 3min, and the granular Al-Fe alloy grains can be formed when AS60 is heated for 2min. Both of these rough surface structures can provide good corrosion resistance after painting. Also, the surface morphology of the precoating was firstly found shows a significant influence on the surface morphology of aluminum-silicon coated press hardened steel part.
