Abstract

The invention relates to a method for manufacturing a Cu-based alloy cladding layer by adopting infrared laser. The method comprises the following steps that chemical copper plating treatment is performed on the surface of a nano reinforced material serving as a deposition substrate, and then the material is chemically plated with a metal layer with high infrared absorptivity to obtain multi-layer-coated Cu-based alloy powder; a common infrared laser is used as a heat source, and a coaxial powder feeding laser cladding technology is adopted for the multi-layer-coated Cu-based alloy powder, so that the Cu-based alloy cladding layer is prepared. According to the technical scheme, the Cu-based alloy cladding layer is processed and manufactured on the surface of a metal component by adopting infrared laser.

Description

technical field [0001] The invention relates to the field of metal material preparation, in particular to a method for manufacturing a Cu-based alloy cladding layer by using an infrared laser. Background technique [0002] Laser cladding technology - a new material preparation technology that uses high-energy laser beams for additive manufacturing. It uses the focused high-energy laser beam as a heat source to melt the metal powder particles that were originally spread on the surface of the metal substrate or fed coaxially in real time to form a molten pool. After the laser beam is removed, the molten pool solidifies rapidly, forming layers of additively manufactured alloys. Laser cladding technology can prepare materials with special functions on the surface of ordinary substrates: such as alloy layers with higher strength, harder, hard and wear-resistant, more corrosion-resistant, more conductive, etc., to improve the service life of metal components or achieve special u...
