Research of Copper Alloys-nickel Composites by Laser Direct Writing

摘要

For the purpose of solve seawater pipe's anti-corrosion materials problem and it is all of varieties, this thesis come up with the copper alloys-nickel composites by Laser direct writing and the method's application and equipment, this thesis also recommend the copper alloys-nickel composites' laser chemical vapor deposition, laser induced liquid deposition, and laser cladding prototyping. To avoid laser cause excess damage to the copper alloys-nickel composites, coating a layer of film of heat actuable adhesive on the basal plate, then pave a layer of copper alloys-nickel composites powder, after rolling use laser heat activate adhesive film, copper alloys-nickel composites used for seawater pipe prepared by laser cladding on copper alloys-nickel composites basal plate. On the copper alloys-nickel composites basal plate laser cladding copper alloys-nickel composites used for seawater pipe anti-oxidation copper nickel alloy layer. Research of laser micro-cladding copper alloys-nickel composites' equipment parameter and optimize, use the copper powder and nickle powder make cupronickel and use the thermosetting resin as adhesive system can make copper alloys-nickel composites on the seawater pipe basal plate, the accuracy is 20μm, the minimum width can under 80μm.
