PLASMA-AIDED MANUFACTURING METHOD FOR OXIDE-DISPERSION-STRENGTHENED PLATINUM MATERIAL

摘要

The present invention relates to a plasma-aided manufacturing method for an oxide-dispersion-strengthened platinum material in which a platinum alloy powder and an oxide are finely dispersed, and has been devised to overcome disadvantages of not only complex manufacturing processes and high manufacturing costs but also lengthy manufacturing times required for manufacturing a platinum alloy powder and an oxide-dispersion-strengthened platinum material according the conventional wet and dry methods. To that end, the purpose of the present invention is to produce an oxide-dispersion-strengthened platinum material in which fine oxide particles are dispersed by manufacturing a platinum alloy ingot by adding, to the platinum, an alloying element for a desired composition; manufacturing a platinum alloy powder by using an environment-friendly plasma method; manufacturing a molding of a predetermined shape from the manufactured platinum alloy powder and applying a high-temperature oxidative thermal treatment to the molding; improving the density of the molding through a high-temperature pressure sintering; and applying hot and cold working to the molding.
