A method for a pressure tight joining of a metallic steering gear housing with a plastic housing cover

摘要

A method for a pressure tight joining of a metallic steering gear housing (1) with a plastic housing cover (2), wherein the metallic steering-gear housing (1) a metallic contact region (3), and the plastic housing cover (2) a plastic contact region (4), wherein the joining connection via the contact regions (3) and (4) is at least by the steps of:- Modification of the surface of the metallic contact area (3) and / or of the plastic contact region (4) by means of a plasma treatment method for achieving a cohesive adhesion after manufacture of the joining connection;- Arrangement of the plastic housing cover (2) in or on the metallic steering-gear housing (1), so that the metallic contact region (3) to the plastic contact region (4), wherein the plastic material of the plastic housing cover (2) has a fixed state of matter;- Introduction of an amount of heat in the plastic material of the plastic housing cover (2), wherein this by the introduction of the amount of heat at least in the region of the plastic contact region (4) is converted into a plasticized state of matter;- Application of a contact force between the metallic steering-gear housing (1) and the plastic housing cover (2) for successively pressing of the plastic contact region (4) on the metallic contact region (3);- Generation of a connection between the material of the metallic contact region (3) and then="16" Plastic contact region (4) by means of the modification of the or of the contact regions (3) and / or (4) and- Solidification of the plastic material of the plastic housing cover (2) by means of the end of the introduction of heat, and, by means of the integral connection of a pressure-tight joining connection between the metallic steering-gear housing (1) and the plastic housing cover (2) is formed.
