    摘要: The method of metal-thermoplastic resin direct bonding is characterized by comprising a first step for irradiating a surface of the metal material with a pulse laser under an oxidizing atmosphere to form a surface modification region, a second step for causing the thermoplastic resin material to abut against the surface modification region to form a bonding interface, and a third step for heating up the bonding interface by laser irradiation to achieve bonding, the first step including forming metal oxide particle clusters obtained when metal oxide particles having a particle diameter of 5-500 nm to be continuously bonded at the surface modification region, so that the maximum height (Sz) of a surface of the metal oxide particle clusters is 50 nm-3 μm.
