Embodiment Construction

[0034] The present invention is described in detail below in conjunction with accompanying drawing as follows:

[0035] The present invention uses high-purity metal elements Zr, Cu, Al, Ni and Ti as raw materials to prepare Zr 52.5 Cu 17.9 Ni 14.6 al 10 Ti 5 Metallic glass master alloy, the purity of each batching element is as shown in Table 1:

[0038] The prepared raw material (30g) is put into the copper crucible in the smelting chamber, and the smelting chamber is vacuumed to 10 -3 Pa below and pass through argon for protection. The pure titanium ingots were smelted 2-3 times before the arc smelting samples to further consume the remaining oxygen in the chamber to prevent the oxidation of th...

Abstract

The invention belongs to the research on improving the corrosion resistance of new structural materials, specifically an optimization process for improving the corrosion resistance of ZrCuNiAlTi bulk metallic glass, which is characterized in that: the atomic percentage is Zr 52.5 Cu 17.9 Ni 14.6 al 10 Ti 5 The alloy composition metal glass is used as the substrate, and the best corrosion resistance is achieved by annealing at 593K for 15 minutes. The present invention selects Vit105 bulk metallic glass as the research object, through the T g The following annealing at different temperatures obtains samples in different degrees of relaxation state. Combined with the corrosion performance test in different solutions, the influence of annealing temperature on the corrosion resistance is obtained, and the corrosion resistance of Vit105 bulk metallic glass is optimized, which is helpful for in-depth understanding of bulk metallic glass. And the scientific and rational application of this new type of functional material has high practical value.

Description

technical field [0001] The invention belongs to the research on improving the corrosion resistance of new structural materials, specifically an optimization process for improving the corrosion resistance of ZrCuNiAlTi bulk metallic glass. The main application fields are surface protection of future naval ships, key equipment of coastal power plants, and surgical operations. Scalpels, artificial bones, electromagnetically stimulated in vivo biosensing materials, artificial teeth, and springs for precision instruments, lightweight casings for automobiles, high-speed rail vehicles, and aircraft, preparation of high-end sporting goods, and transformer cores require good self- Sharp armor-piercing materials, etc. Background technique [0002] Metallic glass is the so-called amorphous alloy. Because of the disordered arrangement of its own atoms, the internal structure does not have defects such as dislocations, grain boundaries, and stacking faults in crystalline alloys, so it ha...
