And in world wide, all carried out the research work of anti-tarnishing silver alloy aspect, under condition, improve the performance of silver alloy fastness cheaply, but produce little effect, fruitful anti-tarnishing silver alloy goods listing that so far there are no.
July 18 in 2007, Zhong state invention patent application publication number CN100999792A disclosed a kind of anti-tarnishing silver alloy, was that to adopt the multiple alloying elements such as rare earth and zinc, silicon, germanium, tin, indium, brill to carry out multi-element alloyed, silver-colored Ag92.5-93.0%, copper Cu3-5%, zinc Znl-3%, germanium Ge0-0.8%, silicon SiO-0.12%, tin Sn0-1%, indium In0-0.5%, yttrium Y0-0.15%, cerium Ce0-0.15%, lanthanum La0-0.15%, cobalt Co0-0.3%, boron-0.1%, magnesium Mg0-0.01%. Although this formula can improve the tissue of alloy, crystal grain thinning, purifies crystal boundary, improve anti-oxidant metachrosis, but this alloy use a large amount of thuliums such as: germanium, yttrium, cerium, lanthanum and cobalt carry out alloying, and cost is still higher, and simultaneously mechanical performance is not high.
Summary of the invention
For addressing the above problem, the invention provides a kind of preparation technology of anti-oxidant color changed silver alloy, in this technique, adopt ternary alloy three-partalloy liquid to be combined with intermediate aluminium alloy technology, make Alloy Anti oxidation stain good, and can reduce silver alloy fusing point, not only can put forward heavy alloyed mechanical performance and processing characteristics, can also improve alloy quality hard and corrosion-resistant and oxidation.
Technical scheme of the present invention is, a kind of preparation technology of anti-oxidant color changed silver alloy, and concrete manufacturing process comprises the following steps:
1) get the raw materials ready: the components in weight percent that weighs following raw materials according: silver-colored 87%-93%, tin 0.5%-2%, zinc 1-2.2%, vanadium 0.5%-3%, manganese 2%-5%, ruthenium 1.5%-3.5%, indium 0.6%-3.1%;
2) vacuum fusion: by the silver of components by weight percent described above, tin and ruthenium heating and melting in vacuum melting furnace respectively, control temperature 500-1000 DEG C, vacuum 0.001Mpa; Mixing and stirring in vacuum environment afterwards, makes Yin-Xi-ruthenium ternary alloy three-partalloy liquid;
3) get the 10%-20% weight portion of ternary alloy three-partalloy liquid gross mass, the zinc, vanadium, manganese and the indium that in normal pressure, add respectively wherein components by weight percent described above to weigh, control temperature 700-1400 DEG C; Mixing and stirring, insulation;
4) by 3) in the intermediate aluminium alloy of step, add to step 2) in remaining ternary alloy three-partalloy liquid; Control vacuum 0.001Mpa, utilize the waste heat of intermediate aluminium alloy, stir rapidly 10 minutes; Emit final silver alloy liquid, in normal pressure, cooling forming obtains silver alloy piece.
The present invention, by add tin in silver alloy, can reduce silver alloy fusing point; Add zinc and can improve the mobility of alloy, and there is bleaching effect. With the comparison of CN100999792A technology, the present invention does not use germanium, yttrium, cerium, lanthanum and cobalt; Creationary use ruthenium, vanadium and manganese. Wherein hard and the corrosion-resistant and oxidation of the quality of ruthenium, can increase non-oxidizability and the wearability of silver alloy; The interpolation of vanadium not only can be made deoxidier, and can increase silver alloy ductility; The interpolation of manganese can improve the hardness of silver alloy. In preparation technology of the present invention, adopt ternary alloy three-partalloy liquid to be combined with intermediate aluminium alloy technology; Make first to make tin, ruthenium oxygen activity element in lower temperature environment, first form stable ternary alloy three-partalloy; Recycling zinc, vanadium, manganese and phosphide element make part ternary alloy three-partalloy form polynary intermediate aluminium alloy, further improve the plasticity of growth mechanism and the oxide-film of oxide, improve the adhesiveness of oxide-film, reduce the tendency of oxide-film cracking, and suppress the illeffects of sulphur. The comprehensive function of these alloying elements of the present invention makes alloy have good anti-sulphide discoloration and anti-oxidant discoloration. Polynary intermediate aluminium alloy of the present invention only accounts for 1/5th or principle still less of whole aluminium alloy, can play effective solution strengthening effect to all ternary alloy three-partalloy liquid alloys, make it have higher hardness, plasticity of the present invention is good, make it to have good mechanical performance and processing characteristics, silver alloy is improved aspect fastness, and be more widely used.
