Effect of electroplating current density on adhesion and peeling properties of 2×0.30HT steel cord
To study effect of electroplating copper process on adhesion and peeling properties of steel cord.Based on diame-ter 1.80 mm steel wire,electroplated steel wires were produced under different average current densities,uneven current current density distributions and different outermost current density.Electroplated steel wire was drawn and twisted into 2 × 0.30HT steel cord with same machine tool and same process,investigate adhesive and peel properties of steel cord under three factors.Results show that average current density of electroplating copper,uneven distribution of current density,and variations in outermost current density within certain range have little effect on adhesion and peeling properties of steel cord.However,as average current density of electroplating increases to 17.07 A/dm2,density of coating deteriorates,leading to stripping properties of steel cord decrease.Meanwhile,compared to outermost current density setting of steel wire,high current density value in first anode frame is more likely to cause poor peeling properties of steel cord.
