Abstract
The invention discloses a method for adopting amorphous alloy to inlay jewels. Block amorphous alloy with the temperature larger than 30 DEG C in an undercooling liquid phase region and a thermoplastic or blow molding process are adopted in inlaying process. Compared with a traditional inlaying process of gold and platinum and the like, the block amorphous alloy is good in plasticity, reduces possible damage to the jewels in process, can be formed by one-time plastic forming, is simple and convenient to operate and short in used time. The amorphous alloy material has extremely high corrosion resistance and can maintain metallic luster in a long term. The optimized block amorphous alloy is mainly Au-based and Pt-based or Pd-based, and the metals belong to precious metals, are high in price and conform to noble properties of the jewels. Simultaneously, the metals have extremely good agreeableness with jewel materials such as Au and Pt in ordinary states, and accordingly an inlaying structure is also connected with a jewel metal base body extremely simply.
Description
Technical field
The present invention relates to a kind ofly adopt block amorphous alloy material thermoplastic shaping or blow molding to plate the fixedly method of jewel.
Background technology
Plate is that a kind of metal that utilizes wraps the cameo incrustation technique that the jewel periphery is inlayed.Compare with other mosaic technologies such as tooth edge, track edge, nail edge, angle edge etc., its characteristics are that seal is large, and fastness is strong.Owing to plate and reduced the brilliance that jewel partly sees through, so be not suitable for jewel transparent and that particle is less, so generally adopt that to plate the jewel particle of inlaying large and abundant, can give the generous sensation of steady noble quality, be suitable for wearing of man and ripe Ms.Plating to be divided into has the limit to plate with boundless to plate, and wherein having the limit to plate is the mode that plates that metal edges parcel is arranged around jewel, boundless plate then be around jewel without the mosaic mode on ring-type limit, be mainly used in inlaying granule jewel or secondary stone.Plate the size of metal edges scope according to parcel and can also be divided into entirely and plate, partly plate with tooth and plate, tooth Bao Ze is called again " cornerite edge " or " horse-eye edge " mainly for the horse-eye jewel.
Present stage, the noble metal used of set jewelry was soft such as gold, platinum, adopted these noble metals as plating material jewel to be plated, and may cause the jewellery noble metal to plate structure and be out of shape in use even cause that jewel comes off.Solution to this problem generally is to add the alloy that alloying component is gained in strength or adopted other higher-strength in noble metal, and such as the 18K gold, 925 silver medals perhaps adopt common metal surface gold-plated.But can cause new problem when increasing jewellery metal part intensity, as because strength increase needs larger squeeze pressure when plating damascene process, but because many jewels all are fragile materials and have blind crack, the improper jewel cracking that very easily causes of the control of squeeze pressure damages when inlaying, and the too high case hardness of metal also may stay cut at some softer jewels when inlaying, and causes heavy losses.Therefore seek a kind of new material, have larger plasticity man-hour plating to add, have higher intensity after the cooling, assurance that just can satisfactory to both parties neat U.S. plates the operability of technique and plates the steadiness of structure.
Summary of the invention
The object of the present invention is to provide the gemmy method of a kind of employing block amorphous alloy bag, its material characteristics is for to have thermoplastic shaping or blow molding ability in supercooling liquid phase region, has high strength, high rigidity, the advantage such as corrosion-resistant after the cooling.
The principle of the invention is: have superplasticity in the supercooling liquid phase region width Delta T x=Tx-Tg scope of non-crystaline amorphous metal Tx between its glass transformation temperature Tg and crystallization temperature, only need the thermoplastic shaping that very little squeeze pressure just can be as plastics, perhaps blow molding.Block amorphous alloy (glassy metal) refers generally to the non-crystaline amorphous metal Δ Tx of supercooling liquid phase region wider width〉30 ℃, utilize these characteristics of block amorphous alloy, maintain the temperature in the supercooling liquid phase region scope that (Tg ~ connection is connected a thermoplastic of structure (or blowing) moulding with the jewellery body Tx) jewellery body, the jewels such as ring necklace to be plated structure, jewel collet.Have the characteristics such as the high strength that surmounts ordinary metallic material, high rigidity, corrosion resistance after simultaneously non-crystaline amorphous metal is cooled under the normal temperature, this has guaranteed that jewel plates the long-lasting of the steadiness of structure and metallic luster.
The technical solution that realizes the object of the invention is: the gemmy method of a kind of employing block amorphous alloy bag may further comprise the steps:
It is 70 ℃＜Tg＜400 ℃, supercooling liquid phase region width Delta T x that step 1. is selected glass transformation temperature〉30 ℃ block amorphous alloy material;
Step 2. is put into mould with jewel and block amorphous alloy, adopts thermoplastic shaping technique or blow moulding process that above-mentioned amorphous alloy material compacting is formed and plates structure.
The preferred Au of block amorphous alloy material described in the step 1 is basic, Pd is basic or Pt is basic.
Block amorphous alloy described in the step 1 can adopt melt supercooled method, copper mold casting method, water quenching or mechanical alloying method preparation.
The temperature of the thermoplastic shaping described in the step 2 or blow moulding process is controlled in the supercooling liquid phase region scope, and namely between glass transformation temperature Tg and the crystallization temperature Tx, thermoplastic extrusion pressure is controlled at 0.05-10MPa, and blowing air pressure is controlled at 50kPa.
The present invention plates material with existing jewellery and technique is compared, and its remarkable advantage is:
1. plate and add thermoplastic (blowing) moulding process that adopts lower temperature man-hour, block amorphous alloy is better with traditional material phase specific plastics such as gold, platinum in the critical cooling rate, has reduced to add may damage jewel in man-hour;
The jewellery body shape, plate structure, jewel collet with the jewellery body connection be connected all can a plastic forming, easy and simple to handle, the time spent is shorter;
3. block amorphous alloy is cooled to the characteristics that have high strength, high rigidity after the room temperature, and the jewel fastness is strong, and retention significantly improves;
4. amorphous alloy material has very strong corrosion resistance, can keep for a long time metallic luster;
From tradition mix improve noble metal intensity different be that the price of block amorphous alloy own is higher, adopts the amorphous alloy material of precious metal-based putting forward the high-intensity value that guarantees simultaneously jewellery.
