Summary: | To make a composite article comprising a copper element (12) and an adhesive material (6) adhesively bonded to a surface thereof, the surface of the copper element is provided with a microstructure comprising knife-shaped elongate projections (14) whose opposite flanks are at an average angle of less than 60 DEG to each other. The microstructure may include rod-shaped projections much smaller than said knife-shaped projections projecting outwardly from the surface of said knife-shaped projections. The knife-shaped projections may be formed by electroless plating and the rod-shaped projections by oxidation and optionally reduction. Bonding strength is improved. |
