Embodiment 1
[0035] The amorphous alloy whose composition is Zr55Al10Cu30Ni5 is melted and cast into a metal mold by die-casting equipment to obtain a flat amorphous alloy plate with a size of 1.5mm×80mm×200mm, and the surface is ground and cleaned to obtain a clean and bright On the surface of the alloy, the critical size of the Zr55Al10Cu30Ni5 amorphous alloy is calibrated by XRD, and the critical size is 6mm; the crystallization volume ratio of the amorphous alloy is tested by XRD, and determined by the method of metallographic observation, and the metallographic observation method is the above-mentioned The flat plate of amorphous alloy is corroded in the corrosive solution. Since the amorphous phase has high corrosion resistance, the crystal phase structure is easily corroded by the corrosive solution and turns black. By measuring the size of the corroded area and the uncorroded area on the surface of the flat plate Ratio, to determine the content of the amorphous phase, the corrosion ...
Embodiment 2
[0038] The amorphous alloy whose composition is Zr55Al10Cu20Ni15 is melted and cast into a metal mold by die-casting equipment to obtain an amorphous alloy flat plate with a size of 1.5mm×80mm×200mm, and the surface is ground and cleaned to obtain a clean and bright On the surface of the alloy, the critical size of the Zr55Al10Cu20Ni15 amorphous alloy is calibrated by XRD, and the critical size is 1 mm; the crystallization volume ratio of the amorphous alloy is determined by XRD and supplemented by metallographic observation. The metallographic observation method is the same as that in Examples 1, the corrosion solution is 10%HF+40%HNO3+50%H2O (volume ratio), and the amorphous phase content is determined to be 60%.
[0039] Then, the prepared amorphous plate was used as an amorphous target, pasted on a water-cooled copper target and placed in a coating chamber for vacuum ion sputtering coating, the target was fixed, and the vacuum chamber was closed to vacuumize to 8×10 -3 Pa,...
