preparation example Construction

[0041] The present invention provides the preparation method of above-mentioned multi-element copper alloy, comprises the following steps:

[0042] (1) Melting electrolytic copper, then adding Ni, CuFe master alloy and CuMn master alloy to carry out the first mixed smelting to obtain a pre-mixed melt;

[0043](2) sequentially adding Zn, Sn, phosphorus copper deoxidizer, refining agent, La or high La mixed rare earth to the premixed melt for the second mixed smelting to obtain a mixed melt;

[0044] (3) The mixed melt is subjected to heat preservation and standing, heating treatment, slag removal and casting out of the furnace in sequence to obtain a multi-element copper alloy.

[0045] The invention melts the electrolytic copper, then adds Ni, CuFe master alloy and CuMn master alloy to carry out the first mixing and smelting to obtain the premixed melt. In the present invention, it is preferable to add electrolytic copper and cover charcoal in the furnace to isolate oxygen; i...

Embodiment 1

[0059] According to the mass percentage of each component of the alloy in Table 1, the multi-element copper alloy is prepared, and the specific preparation method is as follows:

Abstract

The invention provides a multi-element copper alloy, a preparation method thereof and an application in additive manufacturing, belonging to the technical field of additive manufacturing alloy materials. The multi-element copper alloy provided by the invention comprises the following components in mass percent: Sn6.1-11.1%; Zn0.01-1.1%; La or high-La mixed rare earth 0.015-0.2%; Fe0.01-0.3%; Ni0.01~1.0%; P0.01~0.2%; Mn0.01~0.2%; Si0.002~0.015%; Al0.002~0.02%; the balance is Cu. In the present invention, by controlling the mass percentage content of each component in the alloy, the obtained multi-element copper alloy has excellent mechanical properties, corrosion resistance and wear resistance, and can print complex structures, high strength, Parts with good wear resistance, corrosion resistance and high temperature resistance.

Description

technical field [0001] The invention relates to the technical field of additive manufacturing alloy materials, in particular to a multi-element copper alloy, its preparation method and its application in additive manufacturing. Background technique [0002] Additive Manufacturing (AM), commonly known as 3D printing, is a process of extruding, sintering, melting, light-curing, spraying and other methods to process special metal materials, non-metal materials and medical biomaterials one by one through software and numerical control system. A manufacturing technique that builds up layers to create a physical object. Compared with the traditional processing mode of raw material removal-cutting and assembly, additive manufacturing is a "bottom-up" manufacturing method through material accumulation. The manufacture of complex structural parts realized becomes possible. [0003] At present, new copper alloy materials suitable for the additive manufacturing (3D printing) process ...
