High bonding strength of polyphenylene sulfide-aluminum alloy composite structure achieved by constant current anodizing in tartaric acid
Source abstract
Abstract
The high-strength and facile direct joining of metal to polymer has attracted increasing attention in adhesion. The aluminum alloy (Al) specimen was fabricated by constant current anodization and enlarging treatment. The influences of surface energy, porosity, and anodization time on the interface bonding strength of the injection molding polyphenylene sulfide (PPS)–Al composite structures were quantitatively discussed. Results showed that the bonding strength of the joints was significantly affected by the wettability, porosity, thickness, and pore diameter of the anodized aluminum oxide (AAO) films. When the current density and anodization time were 120 A/m 2 and 30 min, the Al surface energy and the bonding strength reached the maximum of 74.8 mN/m and 11.7 MPa. With the enlargement treatment of the AAO film, when the etching duration was 45 min, the bonding strength increased to 25.0 MPa. In general, these results are of great importance to the further design and optimization of the polymer-metal hybrid with reliable interface adhesive strength.
