Methods for pretreating metallic substrate surfaces

Abstract

Method (100) for accelerating a curing process of a thermally conductive adhesive on a metallic substrate, in particular a battery module lid or base, comprising the steps: providing (102) a metallic substrate, laser-based pretreatment (104) of a substrate surface for cleaning and / or structuring, heating (106) the substrate surface by the laser-based pretreatment, applying (108) a thermally conductive adhesive to the laser-pretreated substrate surface, pressing (110) a thermally conductive adhesive with a counterpart, curing (112) the thermally conductive adhesive using the heat introduced by the laser-based pretreatment.
