Improvement of hot galvanizing by nickel under layer

الملخص EN

Zn–Ni alloy based coatings have high corrosion resistance, good adherence and unique physical as well as mechanical properties.

In the present work, nickel was dispersed in the under layer of hot dip zinc coating (Galvanizing).

Showed substantial improvement in physical as well as galvanic performance.

The presence of nickel in the under layer was found to result in good adherence, less porosity and better hardness .The presence of nickel decreases the thickness of the coating and enhances the corrosion resistance character.
