GALVANIZED STEEL SHEET HAVING EXCELLENT COATABILITY, COATING ADHESION, AND SPOT WELDABILITY, AND METHOD FOR MANUFACTURING SAME

摘要

The present invention relates to a galvanized steel sheet, and more particularly, provides a galvanized steel sheet and a method for manufacturing same which can prevent the delamination of a coating film by forming an alloy phase between the steel substrate and the coating film, thereby improving not only coatability and coating adhesion but also spot weldability by increasing the service life of a spot welding electrode.
