Metal powder injection apparatus based on plasma magnetic field impels

The utility model discloses a metal powder injection apparatus based on plasma magnetic field impels. Including feed arrangement, permanent magnet, silicon steel sheet, protective sheath and electrode, it has the gas that is used for producing plasma to be equipped with the meticulous metal powder of process grinding among the feed arrangement and to be full of, feed arrangement's exit linkage to the injection channel by the protective sheath surrounded, the both sides that are located injection channel all are equipped with the electrode, and it is regional to form the internal electric field between the electrode of both sides, the permanent magnet clamp is between upper and lower silicon steel sheet to the parcel is outside the protective sheath, and it is regional to form the external magnetic field, and the electrode produces inside strong electric field, and the protective sheath lies in between the internal electric field region of the external magnetic field region that comprises permanent magnet and silicon steel sheet and electrode production. The utility model discloses can fast, effectively produce plasma to wrapping up by plasma that the metal powder temperature that erupts is high, fast, purity is high, can be applied to fields such as metal cutting, non - metal bonding of the same race, surface coating widely.
