Abstract
Hot press bounding technique was used to join a polyethylene sheet of 4mm thickness to stainless steel AISI 304L of 1mm thickness. Three different process parameters were used during the joining process: pressure of 4, 6, 8 and 10 bar, processing time of 1.5, 2, 2.5 and 3 min. and temperature of 115, 120, 125 and 130°C. The steel surface was treated with two methods: mechanical (scratch) and electrochemical (electro-polishing) treatment. A shear tensile, microstructure, scanning electron microscope and energy dispersive spectrometry tests were used to examine the joint specimens. The effect of process parameters on the joint properties was analyzed by the Minitab program. The scratched and electro-polished joint specimens exhibited a maximum shear force of 1112 and 1022N respectively. The tested joints were failed by an interfacial shear and necking in the polymer side with a ductile fracture. The joining process was occurred by a mechanical interlocking between the molten polymer and pores of the treated surface of steel specimen. The average thickness of the joining line for the scratched and electro-polished specimens was 5 and 4μm.
