Latest Patents

One of Ji-Young Byun's latest patents is a "Method and apparatus for plasma ion implantation of solid element." This invention discloses an apparatus and method that enable plasma ion implantation of a solid element. The process involves placing a sample on a sample stage within a vacuum chamber, which is maintained in a vacuum state. Gas is supplied to the chamber, and a first pulsed DC power is applied to a magnetron sputtering source to generate plasma ions of a solid element. The plasma ions are then implanted onto the surface of the sample. The first power is a pulse DC power capable of applying high power momentarily while maintaining low average power. Additionally, a second power may be supplied to the sample stage, which is a high negative voltage pulse that accelerates the plasma ions towards the sample. This process is synchronized with the pulse DC power for the magnetron sputtering source. Furthermore, inductively coupled plasma can be generated in the vacuum chamber via an antenna to increase the ionization rate of the solid element and lower the operational pressure of the magnetron sputtering source.

Another notable patent is the "Method for manufacturing Fe-Si alloy powders." This invention relates to a method for producing Fe-Si alloy powder. The process includes providing a mixture of AlO powder, an active agent powder, Si powder, and Fe powder. The mixture is heated to a temperature between 700°C and 1200°C in a hydrogen atmosphere. Following this, a Fe-containing material is magnetically separated from the mixture, and the Fe-Si alloy powder is obtained by soaking the Fe-containing material in an alkali solution. During the heating process, the Si powder is deposited on the surface of the Fe powder and diffuses into it.
