JOINING OF POLYMER AND SURFACE-MODIFIED METAL BY LASER WELDING |
摘要 |
The present invention relates to a method of joining a metal part 1 and a non-liquid polymer part 2. The first step of the method is to attach a primer 4 to a metal surface 3 of the metal part 1. The primer 4 is then polymerized so that the metal surface 3 is at least partly covered with surface immobilized polymer brushes 5. Then the metal surface 3 with the polymer brushes 5 is brought into contact with a polymer surface of the polymer part 2, so that an interface is obtained comprising the metal surface 3, the primer 4, the polymer brushes 5 and the polymer surface. Finally, the interface is heated by use of laser welding until the polymer brushes 5 and a part of the polymer part 2 melt or soften and mix to such an extent that the metal part 1 and the polymer part 2 remain joined after cooling. The welding may e.g. be performed so that so that welding seams are obtained along equidistant lines across the surface. |
