Embodiment 1
[0028] A zirconium-based amorphous alloy is provided. In this embodiment, a Zr-Cu-Ni-Al-Sn alloy is used as a base material, and aluminum metal powder is provided.
[0029] A surface treatment method for amorphous alloys, comprising the following steps:
[0030] Step 1, cold spraying: spray a layer of aluminum metal layer on the surface of Zr-Cu-Ni-Al-Sn alloy by cold spraying method to obtain a semi-finished product; The gas accelerates the aluminum metal powder to 750m / s, so that the aluminum metal powder passes through the focusing-diverging nozzle for cold spraying and injects the surface of the Zr-Cu-Ni-Al-Sn alloy along the axial direction to form a uniform and dense Aluminum metal layer; in the present embodiment, the porosity of the aluminum metal layer is 0.5%, and the thickness of the aluminum metal layer is 50 μm;
[0031] Step 2, anodizing treatment: anodize the aluminum metal layer in the semi-finished product obtained in step 1 to form an aluminum oxide film on ...
Embodiment 2
[0034] A zirconium-based amorphous alloy is provided. In this embodiment, a Zr-Cu-Ni-Al-Nb alloy is used as a base material, and aluminum alloy 6061 powder is provided.
[0035] A surface treatment method for amorphous alloys, comprising the following steps:
[0036] Step 1, cold spraying: on the surface of the Zr-Cu-Ni-Al-Nb series alloy, spray one layer of aluminum alloy layer by cold spraying method to obtain a semi-finished product; the specific method is: with a pressure of 450 psi The gas accelerates the aluminum alloy powder to 800m / s, so that the aluminum alloy powder passes through the focusing-diverging nozzle for cold spraying and injects the surface of the Zr-Cu-Ni-Al-Nb alloy along the axial direction to form a uniform and dense Aluminum alloy layer; in the present embodiment, the porosity of the aluminum alloy layer is 1%, and the thickness of the aluminum alloy layer is 65 μm;
[0037] Step 2, anodizing treatment: anodize the aluminum alloy layer in the semi-fi...
Embodiment 3
[0040] A zirconium-based amorphous alloy is provided. In this embodiment, a Zr-Cu-Ni-Al-Nb alloy is used as a base material, and aluminum alloy 6063 powder is provided.
[0041] A surface treatment method for amorphous alloys, comprising the following steps:
[0042] Step 1, cold spraying: on the surface of the Zr-Cu-Ni-Al-Nb series alloy, spray a layer of aluminum alloy layer by cold spraying method to obtain a semi-finished product; the specific method is: the pressure is 400 psi The gas accelerates the aluminum alloy powder to 650m / s, so that the aluminum alloy powder passes through the focusing-diverging nozzle for cold spraying and injects the surface of the Zr-Cu-Ni-Al-Nb alloy along the axial direction to form a uniform and dense Aluminum alloy layer; in the present embodiment, the porosity of the aluminum alloy layer is 0.9%, and the thickness of the aluminum alloy layer is 80 μm;
[0043] Step 2, anodizing treatment: anodize the aluminum alloy layer in the semi-finis...
