| Research Abstract |
Feasibility of a new hydroforming technique for small diameter (at most 10-mm-outer-diameter) tubing was evaluated. The technique uses the friction between the tubular specimen (8 mm outer-diameter, 0.8 & 0.5mm thick) and the forming die to control the deformation behavior of the specimens made of copper tubing and aluminum tubing. Electroless plating (0.01mm thick) was adopted to change the frictional surface condition of a cross-shaped forming die and a tee-shaped die.
Effect of the surface-plating on the tube deformation weakly appeared in this experimental study. It depended on the forming shape. Besides, it depended on the location of the plating. However, there might have been unclear effect of the contact pressure and plating thickness on the tube deformation.
