Method of manufacturing high-strength pure gold (24 gold) by injection of trace elements and nitrogen

摘要

The present invention can not be used as a pure gold decorative material because the strength (Hv 32) of the conventional pure gold (24K) is too low to be commercialized, even though it has good color and high property value. ), But it is not suitable for large-sized products other than its strength. In order to use it as a pure-gold decorative material, it must have a strength Hv of 100 or more and its strength should not be deteriorated over time. At present, there is little ornameness of pure gold (24K) in Korea, and the products that are sometimes released are only a few large ones, and it is impossible to produce thin or fine precision decorative products because of low strength. In Japan, 24K hardened gold content (24K) and trace elements (Mg, Al, Si, Mn) in a vacuum furnace or a general induction furnace in order to solve the problem that it was difficult to see pure gold (24K) , Fe (Co.), Ni (Cu), Pd (IN) Sn, Sb, Pb, Bi, Be, Ge, Ti. (24K) decorative material having a high strength and a purity of 99.97% or more.
