【目的】非晶态合金是一种新型的金属材料,其长程无序的原子结构导致其具有优异的力学性能,因此,有必要研究利用非晶态合金来提高普通材料性能的具体方案。【方法】通过快速熔体浸润抽拉包覆的方式,把Zr基非晶态合金材料快速包覆于铜线表面。【结果】非晶态合金包覆层可以有效地提高铜线的抗压强度,同时由于包覆层优异的抗腐蚀性,所制备的非晶态合金包覆铜线材料也具有优异的抗腐蚀性能。同时还发现铜线的包覆层厚度随着抽拉速度的增加而减小。随着包覆层厚度的增加,样品的屈服强度也逐步提高,但是不能无限度增加包覆层厚度:由于冷却散热问题,当包覆层厚度超过120μm时,包覆层合金会形成明显的晶化相,晶化后的包覆层不具备非晶态合金的高强度,从而不能提高铜线的力学性能。【结论】非晶态合金包覆层超高的强度和抗腐蚀性可以有效地改善铜线的力学和抗腐蚀性能,从而增强铜线环境耐受力,使之具有更广泛的应用价值。
【Objective】 Amorphous alloy is a new type of metal material. Its long-range disordered atomic structure leads to its excellent mechanical properties. Therefore, it is necessary to study the use of amorphous alloys to improve the performance of common materials. 【Method】 Zr-based amorphous alloy was rapidly coated on the surface of copper wire by rapid melt infiltration drawing and coating. 【Result】 The amorphous alloy coating can effectively improve the compressive strength of copper wire. At the same time, due to the excellent corrosion resistance of the coating, the prepared amorphous alloy coated copper wire material also has excellent corrosion resistance performance. At the same time, it was also found that the thickness of copper claddings decreases with the increase of drawing speed. With the increase of the thickness of the coating, the yield strength of the sample is gradually increased, but the thickness of the coating can not be increased indefinitely: due to the problem of cooling and cooling, when the thickness of the coating exceeds 120 μm, the coating alloy forms obvious crystal Phase, the coating after crystallization does not have the amorphous alloy of high strength, which can not improve the mechanical properties of copper wire. 【Conclusion】 The high strength and corrosion resistance of amorphous alloy coating can effectively improve the mechanical properties and corrosion resistance of copper wire, thus enhancing the environmental resistance of copper wire and making it more widely used.
