Abstract: Disclosed is a method of producing a rare earth permanent magnet, comprising: obtaining a NdFeB sintered magnet; applying a mixed powder including a Zn-containing metal and a metal compound containing Tb or Dy onto a surface of the sintered magnet; and heat-treating the sintered magnet having the mixed powder applied on its surface.

Abstract: A magnesium oil pan prevents noise and vibration by attaching reinforcement members to portions that are weak in strength and are vulnerable to vibration. The magnesium oil pan includes a flange formed on an upper surface of the oil pan so as to be coupled with the cylinder block, a lower oil pan coupler formed on a lower surface of the oil pan so as to protrude downwards, and a bracket formed on a lateral surface of the oil pan so as to be coupled with a chain cover of the engine. The lower oil pan coupler includes a main reinforcement rib on an inner side of the oil pan which continuously runs between opposite inner walls of the lower oil pan coupler and protrudes downwards. Thus, the magnesium oil pan is made lightweight, improves noise-proof performance, and is hardly damaged by external impacts.

Abstract: The present invention is directed, in general, to an apparatus for recycling magnesium alloy scrap. In particular, an apparatus for recycling magnesium alloy scrap includes a melting furnace formed with a tapping part, having a first filter for removing impurities present in molten scrap, and capable of being tilted toward the tapping part; a first cleaning furnace disposed on a side of the melting furnace, having a gas injecting part for injecting an inert gas in the molten metal and capturing and removing impurities present in the molten metal, and capable of being tilted; a second cleaning furnace disposed on a side of the first cleaning furnace, and having a pump to tap a predetermined amount of the molten metal supplied from the first cleaning furnace and a second filter to remove impurities in pumped molten metal; and an ingot forming furnace disposed on a side of the second cleaning furnace, and configured to form an ingot using the predetermined molten metal supplied from the second cleaning furnace.
