“…Laser treatment is much simpler, efficient, and environmentally friendly than traditional chemical treatment or electrochemical treatment. [25,26,28,32] Therefore, it is, no doubt, a more promising strategy.…”

“…[11,22,23] The technology first scales the metal surface at the nanoscale or the microscale, and then projects the plastic directly onto the metal surface, thereby forming the metal and the plastic into one body. [6,[24][25][26][27] Not only it balances the appearance of metal, but also simplifies the design of product structural components, making the product lighter, thinner, shorter, and smaller. For direct molding bonding, the surface pretreatment of metals is the key to obtaining a high-strength PMH.…”

“…However, treatment methods proposed in previous studies required various hazardous chemical reagents (e.g., acid, hydrazine hydrate, and sodium hydroxide solution). [25,26,28] In today's increasingly environmentally friendly and economical production requirements, it is urgent to find a new surface treatment method to achieve the same purpose.…”

“…For direct molding bonding, the surface pretreatment of metals is the key to obtaining a high‐strength PMH. [ 24–26 ] Li et al prepared a PMH of polyamide/aluminum. [ 24 ] To improve the bonding strength with polymer, the surface of Al alloy was treated by sandblasting using a blasting machine, and the maximum bonding strength of the prepared PMHs was 5.9 MPa.…”

“…[ 25 ] The electrochemical treatment was also used by Kadoya et al to treat the metal. [ 26 ] They prepared a series of PMHs based on polybutylene terephthalate (PBT) and Al alloy, and the maximum bonding strength of PMHs was around 21.0 MPa. In our previous work, [ 28 ] the traditional chemical method was used to pretreat the surface of metals to produce nanopores.…”

The spread of integrated structural elements and parts made from low‐density materials (for example aluminum and polymers) created a need for joining technologies with which these can be joined. Herein, the most important surface preparation methods and joining processes, with which the surface structure of aluminum can be modified and aluminum and polymer structures can be joined, are reviewed. For both topics, a new classification method is introduced: surface preparation methods are grouped based on the method of creating surface structures, whereas joining technologies are grouped according to heat input and structural changes in the polymer material. Herein, “hot” joining technologies (in which so much heat is formed that the polymer material is melted) are reviewed. This grouping category includes techniques based on friction and induction, ultrasonic and laser welding, and some in situ joining technologies. With these, materials with highly different chemical structures and melting temperatures are joined in fast cycles, in a reliable manner. In the coming years, more integrated structures containing aluminum–polymer joints manufactured with fast, automatable joining techniques (such as ultrasonic and laser welding, in compliance with the requirements of Industry 4.0) will be used throughout the industry.

The metal-plastic combination is widely used in frontier fields such as energy storage technology and aerospace. This study proposes two metal surface treatment processes for metal-plastic composite injection molding. The first only involves the chemical treatment, whose interfacial bonding strength reaches 10.24 MPa. In the second, the plasma treatment is added to the chemical treatment process to increase the interface bonding strength to 17.58 MPa. The characterization result shows that the plastic is injected into the undercut microstructures to form a physical bolting force due to the countless microstructures after the metal surface treatment. Through the step-by-step study of the surface treatment process, it is found that hydrochloric acid solution causes a large-scale microstructure to appear on the metal surface, and the undercut nanostructure is obtained through the plasma treatment.
