Abstract
The present invention relates to a kind of gold-plating process that is applicable to Watchcase and jewellery etc.The present invention utilizes special high energy art breading, atoms such as hard element chromium, copper are embedded in the structure of gold, thereby the variation that changes its structure reaches superhard purpose, compare with conventional craft of gilding, keep under identical performance and the life-span condition, can save drain of gold amount 40%～60%, and keep the galvanized color of proof gold.According to user's requirement, plate the face gold layer of different color and lusters at last.
Description
The present invention relates to a kind of gold-plating process that is applicable to Watchcase and jewellery surface.
At present, many gold-plated products are arranged on the market, generally all there is such or such deficiency, domestic manufacturer takes conservative plating method for wrist-watch appearance component and jewellery are gold-plated always, electroplate with proof gold or the above karat gold of 14K, cost an arm and a leg owing to making cost to descend with the gold amount, common citizen is not dared to inquire expensive goods is forbidding; Though in those, the low grade products price is lower, its life-span is short unsatisfactory again and do not reach requirement.
Therefore, task of the present invention is in order to adapt to the needs of domestic market, to overcome the deficiencies in the prior art, obtaining planting product both inexpensive and that the life-span is long.
The present invention is achieved by following method: take a kind of special gold-plating process: promptly at watchcase, on the bright nickel layer on the surface of jewellery earlier plating one deck Gold Content lower and anticorrosive with wear resistance preferably Wimet make bottom, and then good 23K master's gold layer 1 μ of plating wear resistance, and utilize a kind of high energy technology, hard element chromium, atoms such as copper are embedded in the structure of gold, thereby the variation that changes its structure reaches superhard purpose, compare with conventional craft of gilding, keep under identical performance and the life-span condition, can save drain of gold amount 40%～60%, and keep the galvanized color of proof gold.According to user's requirement, plate the face gold layer of different color and lusters at last.
Fig. 1 of the present invention by top layer substrate 11, bright nickel layer 12, special alloy layer 13, contain Cr, Cu element layer 14, main gold layer 15 and face gold layer 16 and form.Bright nickel layer 12 of the present invention is 2～4 μ; Special alloy layer 13 is 2～4 μ; Contain Cr, Cu element layer 14 is 0.1～0.5 μ; Main gold layer 15 is 0.5 ± 20% to contain the wear-resisting gold of gold 99%; Face gold layer 16 is 0.05～0.1 μ.
The present invention realizes by the schema of Fig. 2: at first needs gold-plated watchcase or jewellery are made ultrasonic cleaning, put on the shelf then by the blank check, again through chemical deoiling and degreasing, the secondary washing, the nickel recovery is dodged in activation washing again, the secondary washing, and the first gold medal layer is that plating one deck Gold Content is lower and anticorrosive fine good with wear resistance earlier on bright nickel layer, the color and luster Wimet of very similar karat gold is again made bottom, and hard gold layer is made up of Au, Cu, Zu, Pb.Through surface treatment, utilize special high energy technology, atoms such as hard element Cr, Cu are embedded in the structure of gold, its structure is changed, reach superhard purpose.At last according to user's needs can topped 14K, 18K, 24K color and luster extexine.Characteristics of the present invention, the over-all properties that keeps conventional craft of gilding, and measure than pure gold-plated saving 60% with gold, electroplate saving 40% than karat gold, with conventional craft of gilding plating man, woman's watchcase is an example, 10 watchcases of average every gram gold plating, to plate 1,000,000 calculating year, conventional craft of gilding needs 100 kilograms of gold, and adopts processing method of the present invention only to need 40 kilograms of gold, can save 60 kilograms of gold, moreover the annual watchcase that need be gold-plated in the whole nation, jewellery run far deeper than 1,000,000, if visible processing method large-scale popularization of the present invention is used, can save the gold resource of a large amount of preciousnesses every year, for the user cuts down expenses, capture the domestic market.
Claims (2)
