Title: Innovations of Takeshi Sakuma in Aluminum and Metal Casting
Introduction
Takeshi Sakuma is a notable inventor based in Tokyo, Japan. He has made significant contributions to the fields of aluminum sintering and metal casting. With a total of 3 patents to his name, his work has advanced the technology used in these processes.
Latest Patents
One of Sakuma's latest patents is a process for producing aluminum sintering. This innovative method involves maintaining a rare gas atmosphere inside a sintering furnace while heating a compact of aluminum particles or aluminum alloy particles, along with a magnesium source. The process reduces the pressure inside the furnace while further heating, which sublimates magnesium nitrogen to generate Mg₃N₂. This generated compound then interacts with Al₂O₃ on the surface of the compact, facilitating the reduction of Al₂O₃. As a result, the heating and sintering occur at a temperature lower than the melting point of aluminum. This method enhances the bonding strength of aluminum alloy particles and improves the yield point, strength, and elongation of aluminum sinterings.
Another significant patent by Sakuma is a process for casting a fiber-reinforced metal body. This process involves placing a shaped fibrous article made of a reinforcing fiber into a cavity in a casting mold. Molten metal is then filled into the shaped fibrous article to solidify it. The process includes pouring the molten metal into the cavity from the lower portion while venting gas through a small opening in the upper portion of the cavity. The gas vent passage is then closed, allowing the molten metal to completely solidify under higher pressure.
