Tīmeklis2014. gada 6. jūn. · It signifies that Fe-Zn flash-coated GA steel sheet is easy to weld and has better weldability compared to bare GA steel sheet. The reduction of welding current (0.5 kA) for Fe-Zn flash-coated GA steel sheet can be explained by the similar observation reported by Hu et al. (Ref 28) on different Fe contents in GA coating. TīmeklisZinc plating is an economical sacrificial coating to protect parts from corrosion. Post-plate treatments, such as chromates and sealers, can offer additional protection.
