Sticking-up Behaviors and Surface Friction of IF Electrogalvanized Sheet Steel in Forming

X-ray diffraction (XRD), ball-disc friction and wearing machine and draw-bead test were introduced to investigat the strcusture and workability of IF sheet steel electrogalvanized deposits prepared from sulphate solution system. It was shown that the picking-up of the zinc coating on die strengthened with the increasing of friction factor which was originally affected by the coating’s structure. Duing forming, (00X) planes (X=2, 4) preferential orientation of zinc deposits increased, which resulted in enhancing the coating’s friction behaviors. Therefore, the forming mechanism of electrogalvedzed deposit was demonstrated that both friction and the stricking-up behaviors of the coating are intensified simultaneously and affect each other.
