| description | The invention relates to a preparation method of a platinum-ruthenium-gallium alloy for platinum jewelry, which comprises the following steps: (1) sequentially carrying out vacuum melting and casting on platinum, ruthenium and gallium raw materials to obtain a cast ingot; (2) the cast ingot obtained in the step (1) is subjected to homogenization treatment, hot forging and cold rolling in sequence, and the platinum ruthenium gallium alloy is obtained; the single-pass deformation of cold rolling is less than or equal to 8%. The prepared platinum-ruthenium-gallium alloy is high in hardness, white in color and luster, bright in surface, free of tool sticking during turning and suitable for preparation of platinum jewelry.
本发明涉及一种用于铂金首饰的铂钌镓合金的制备方法，所述制备方法包括以下步骤：(1)将铂、钌和镓原料依次进行真空熔炼和浇铸，得到铸锭；(2)将步骤(1)所述铸锭依次进行均匀化处理、热锻和冷轧，得到铂钌镓合金；所述冷轧的单道次变形量≤8％。本发明制得的铂钌镓合金硬度大、色泽白、表面光亮、车削不粘刀，适用于铂金首饰的制备。 |
