Embodiment 1
[0024] Embodiment 1: A kind of powder core wire material and preparation method thereof for the preparation of Al-Ni-Zr-Cr amorphous coating by high-velocity arc spraying technology
[0025] First roll a 10×0.4 (width 10mm, thickness 0.4mm) pure aluminum strip into a U shape, and then according to the mass percentage of powder core wire: 16% Ni, 8% Zr, 8% Cr, weigh For re-batching, put the obtained powder into the powder mixer and mix it for half an hour, then add it to the U-shaped aluminum tape tank, the filling rate is 32%, and then close the U-shaped aluminum tape tank to make the powder cover it, and finally pass multiple times. After the drawing wire is reduced to a diameter of 2.0mm, it is wound into a disc shape, and after being measured and packaged, it becomes a product that can be shipped.

Embodiment 2
[0028] Embodiment 2: A kind of powder core wire material and preparation method thereof for the preparation of Al-Ni-Zr-Cr amorphous coating by high-velocity arc spraying technology
[0029] First roll a 10×0.4 (width 10mm, thickness 0.4mm) pure aluminum strip into a U shape, and then weigh the ingredients according to the mass percentage of the powder core wire material powder core: 24% Ni, 12% Zr, and put Put the powder into the powder mixing machine and mix it for half an hour, then put it into the U-shaped aluminum tape groove, the filling rate is 36%, then close the U-shaped aluminum tape groove to coat the powder, and finally reduce the diameter by multi-channel wire drawing After reaching a diameter of 2.0 mm, it is wound into a disc shape, and after being measured and packaged, it becomes a product that can be shipped.
[0030] Taking the powder core wire material prepared in Example 2 as material, the spraying process parameters used to prepare the amorphous coating b...
Embodiment 3
[0032] Embodiment 3: A kind of powder core wire material and preparation method thereof for the preparation of Al-Ni-Zr-Cr amorphous coating by high-velocity arc spraying technology
[0033] First roll a 10×0.4 (width 10mm, thickness 0.4mm) pure aluminum strip into a U shape, and then according to the mass percentage of powder core wire: 20% Ni, 14% Zr, 6% Cr, weigh For re-batching, put the obtained powder into the powder mixer and mix for half an hour, then add it to the U-shaped aluminum tape groove, the filling rate is 40%, then close the U-shaped aluminum tape groove to coat the powder, and finally After the drawing wire is reduced to a diameter of 2.0mm, it is wound into a disc shape, and after being measured and packaged, it becomes a product that can be shipped.
[0034] With the powder core wire material prepared in Example 3 as material, the spraying process parameters used for preparing the amorphous coating by high-speed arc spraying technology are: spraying current...
