Embodiment 1
[0028] Preparation of copper wire, boronized iron wire and nitrided iron wire:
[0029] Preparation of copper wire, nitriding iron wire and boronizing iron wire: the diameter is 1mm, and the composition is pure copper;
[0030] Take the iron wire with a diameter of 1mm, composition weight percentage: C is 0.05%, Si is 0.2%, Mn is 0.25%, P<0.02%, S<0.025%, the rest is Fe, and the overall length of the iron wire used is copper wire Twice of that; copper wire and iron wire account for 15% of the volume of the material.
[0031] Boronizing the surface of the above half iron wire and nitriding the other half of the iron wire according to the conventional method respectively form boronizing iron wire and nitrided iron wire; Nitriding iron wire and copper wire have the same length;
[0032] According to the conventional method of cleaning ball production, take one wire each of the above-mentioned copper wire, boronized iron wire and nitrided iron wire to form a spherical mixed thre...
Embodiment 2
[0036] Magnesium alloy material matrix composition by weight percentage: Al is 12%, Co is 0.5%, Si is 6%, Pb is 3%, Sn is 3%, Fe is 2%, Gd is 1%, Pr is 0.03% , and the rest is Mg for batching.
[0037] The copper wire is pure copper; the weight percentage of iron wire components: C is 0.09%, Si is 0.3%, Mn is 0.35%, P<0.02%, S<0.025%, and the rest is Fe. The diameters of the iron wire and the copper wire are both 2mm, and the overall length of the iron wire used is twice that of the copper wire, and the volume percentage of the two kinds of metal wires is controlled to be 35% of the material.
[0038] Boronizing the surface of the above half iron wire and nitriding the other half of the iron wire according to the conventional method respectively form boronizing iron wire and nitrided iron wire; the thickness of the nitriding layer and the boronizing layer is 300 microns; Nitriding iron wire is just suitable with copper wire length; The three kinds of metal wires that the conv...
Embodiment 3
[0041] Magnesium alloy material matrix composition by weight percentage: Al is 11%, Co is 0.4%, Si is 5%, Pb is 2.5%, Sn is 2.5%, Fe is 1.5%, Gd is 0.8%, Pr is 0.02% , and the rest is Mg for batching.
[0042]Boronizing is pure copper. The composition of iron wire is 0.07% C, 0.25% Si, 0.3% Mn, P<0.02%, S <0.025%, and the rest is Fe. Iron wire and copper wire wire diameter are 1.5mm, and the overall length of used iron wire is twice of copper wire, and control two kinds of metal wires to account for the volume percentage of material altogether is 20%.
[0043] Boronizing the surface of the above half iron wire and nitriding the other half of the iron wire according to the conventional method respectively form boronizing iron wire and nitrided iron wire; the thickness of the nitriding layer and the boronizing layer is 250 microns; Nitriding iron wire is just suitable with copper wire length; The three kinds of metal wires that the conventional method that cleaning ball is pro...
