Integrated manufacturing of REciclable multi-material COmposites for the TRANSport sector

An anti-corrosion and anti-fouling composite treatment method for the surface of an additive manufacturing metal part, comprising: 1, preparing a metal part base by using a selective laser melting method; 2, performing shot blasting treatment on the surface of the metal part base to obtain a defect hardened layer; 3, obtaining an ion intermixed layer by means of magnetron sputtering high-energy bombardment pretreatment; and 4, finally, depositing a nano-composite multi-layer nitride coating by means of a magnetron sputtering method, wherein the internal structure of the nano-composite multi-layer nitride coating comprises an elemental metal bonding layer, a nitrogen element transition layer, a nano multilayer containing a main alloy element, and a nano-composite top layer containing an active metal. By means of the composite treatment method for performing shot blasting strengthening treatment on the surface of the additive manufacturing metal part and depositing the coating by means of the magnetron sputtering method, a film-based system having good comprehensive mechanical properties is constructed; in the coating, the main alloy element improves the strength and the corrosion resistance, and the active metal element enhances antibacterial and anti-fouling properties, thereby achieving long-term corrosion prevention and pollution prevention; and the method has a broad application prospect in the field of marine transportation metal part manufacturing and surface protection.
