Description

The goods of golden surface

The present invention is a kind of goods of golden surface, belongs to from coating technique.

At present people have worked out various ion film-plating methods such as so-called physical vapor deposition and chemical vapour deposition, the application of these methods, make on external ornament and goods, be coated with golden TiN, ZrN, the TaN coating becomes possibility.Though yet the coating that makes like this has the color of similar gold, but still there is a big difference for the luxurious tone that natural gold had that the gold color and luster of coating compares, goods chromatic aberration defect for uneven surface is just more obvious, and this gilt can only be used for limited several external ornaments and goods, in order to improve this situation United States Patent (USP) 912,548 at its golden TiN, ZrN, plate the mixture film of one deck TiN and metal on the TaN coating again, its shade deviation is apart from increasing, but the rarer vegetables of rete quality, porosity is higher, and sticking power is relatively poor, and is corrosion-resistant, abrasion resistance properties is also relatively poor, and tone be difficult for to be adjusted, this technological operation inconvenience of getting up, and cost is also higher.

The objective of the invention is provides a kind of goods of golden surface in order to improve above-mentioned deficiency, first rete of this goods is oxide compound, oxynitride, nitrogen carbide, the nitrogen-oxygen carbide of metal or nonmetal silicon, second rete is single transparent metal layer as thin as a wafer, the 3rd layer is gold or au-alloy rete, it promptly has corrosion-resistant, anti abrasive advantage, it is high in uneven surface plated film smooth finish to eliminate TiN again, the shortcoming that quality is fineless and smooth, and the coating tone is near natural gold or alloy tone.

The present invention is the goods of golden surface, form by the coating that heat-stable matrix and three retes on it are formed, first rete is the oxide compound of metals such as the Ti that is connected mutually with heat-stable matrix and nonmetal silicon, oxynitride, nitrogen carbide, nitrogen-oxygen carbide, nitride; Second rete is the transparent single intermediate metal as thin as a wafer that is made of pure metal such as Ni that is connected mutually with first rete, and the tertiary membrane layer is gold or the au-alloy rete that is connected mutually with second rete.These goods also can be made up of the coating that two retes on matrix and its are formed, and first rete is oxide compound, oxynitride, nitrogen carbide, nitrogen-oxygen carbide, the nitride of metal such as the Ti that is connected mutually with matrix and nonmetal silicon; Second rete is gold or the au-alloy rete that is connected mutually with first rete.These goods also can be made up of rete on matrix and its, this rete is the oxide compound of metals such as the Ti that is connected mutually with matrix and nonmetal silicon, oxynitride, nitrogen carbide, nitrogen-oxygen carbide, the mixture of nitride and gold or au-alloy, or one-tenth golden, au-alloy is grouped into, by the outside surface of heat-resisting matrix, can change to absolutely by zero to rete.Coating is ion plating, the sputter plating, and vacuum evaporation coating, plating, chemical plating coating, the base material of goods is made of steel, brass, nickel, silver, aluminium alloy, pottery, plated item or heat stable resin.

The present invention makes bottom membrane with oxide compound, oxynitride, nitrogen carbide, the nitrogen-oxygen carbide of metal or nonmetal silicon, the membrane-coating granules exquisiteness, porosity is low, quality is intensive, corrosion-resistant, the abrasion resistance properties height, color easily changes with the change of thicknesses of layers, color is various, can adapt to the color of various extexines, and selection range is very big, the present invention is second rete with transparent single metal, coating process is simplified greatly, and good with the sticking power of substrate, makes outermost gold and au-alloy rete be easy to lining.

Below the present invention is described in detail.

In example one, the ion film coating machine of packing into after Stainless Steel Watch Case cleaned, coating chamber is evacuated to 6.6 * 10 ^-3Pa charges into argon gas to 2～3Pa, and the volts DS that watchcase is applied 1KV bombards cleaning then.Behind the end of bombardment, continue to vacuumize.Subsequently to coating chamber (3-6) * 10 that fill oxygen ^-1Pa opens evaporation source in the case and makes Ti evaporation ionization, forms plasma body, the Ti ion that is evaporated ionization reacts with the oxygen of sending into, generate rose golden titanium oxide layer on watchcase surface, and then to plate second rete be Ni transparent metal layer as thin as a wafer, vacuum is evacuated to 6.6 * 10 ^-3Charge into Ar gas to 4 * 10 behind the Pa ^-2Pa, open evaporating and ionizing source, make Ni evaporation ionization form plasma body, lining is on TiO, it is the transition layer as thin as a wafer of layer of transparent, this rete only plates a kind of coating process of metal and has simplified the technology of plating the mixture film of TiN and metal in the prior art greatly, and the sticking power enhancing, and helps the lining of tertiary membrane layer gold.After this, again coating chamber is evacuated to 6.6 * 10 ^-3Pa makes golden heating evaporation ionization with evaporation source, and the watchcase that is coated with such coating will present the color that is similar to natural gold, and along with the increase of metal thickness, the tone of gold layer is more and more near pure gold tone.When outermost layer gold layer thickness by 700A(0.07 μ m) when increasing to 1 μ m, plate the also variation thereupon of tone of decorating plating.Even gold wears away prematurely and exposes following coating, but because coating is harder, and being gold tone, any concentrated wear of extexine gold layer is all unimportant.Utilize the thickness that changes coating to reach and change the substrate surface coating color, make it color near surface gold layer.

Example two, Stainless Steel Watch Band is cleaned back ion plating one deck silicon oxynitride, method and example together, different is, and also to charge into its ratio of nitrogen when charging into oxygen be N ₂: O ₂=100: 8, the evaporating and ionizing source of this moment makes Si evaporation ionization, uses ion electroplating method flash layer of transparent metal Ni as thin as a wafer then, uses electrochemical method at Ni surface deposition layer of Au-Ni-Cu alloy at last.The watchband that makes like this, existing luxurious gold tone good wear resistance and erosion resistance are arranged again, and cost is lower.

Example three, Stainless Steel Watch Band is cleaned back ion plating one deck TiCN, this technology is with example one, and what charge into simultaneously to coating chamber in this technology is nitrogen and carbon (acetylene), and its amount is than being N ₂: C=100: 4.Use ion electroplating method flash transparent layer of Ni as thin as a wafer then, use electrochemical method at last at Ni surface deposition one deck gold.

Example four, Stainless Steel Watch Band is cleaned back ion plating one deck nitrogen oxygen titanium carbide, this method and example together after just bombardment vacuumizes, promptly charge into nitrogen to coating chamber simultaneously, and it measures oxygen and carbon (acetylene) than being: N ₂: O ₂: C=100: 3: 5.Use ion electroplating method flash layer of transparent Ni as thin as a wafer then, use electrochemical method at last at Ni surface deposition one deck gold.

Example five, with one through electrochemistry nickel plating or chromed brass watch case, in the ion film coating machine of packing into, to its coating of ion plating one deck ZrO and gold respectively, method is identical with example one.As external ornament, its color and luster and gold are very nearly the same.

In example six, the ion film coating machine of packing into after Stainless Steel Watch Case cleaned, coating chamber is evacuated to 6.6 * 10 ^-3Pa charges into argon gas to 2～3Pa, and the volts DS that watchcase is applied 1KV bombards cleaning then, behind the end of bombardment, continues to vacuumize, subsequently to coating chamber inflated with nitrogen (3～6) * 10 ^-1Pa opens evaporation source in the case and makes Ti and Au evaporation ionization, forms plasma body, and the Ti and the Au ion that are evaporated ionization react with the nitrogen of sending into, and generate the mixture film of rose golden TiN and Au immediately on the watchcase surface.Therefore this method is coated with very easy because of only need be coated with the mixture film of one deck TiN and Au on plating piece.

Base materials all in above-mentioned all examples can be not limited to stainless steel and brass, and other usually also can be as base material of the present invention as the material that outer decorative element adopted as copper alloy, aluminium alloy etc.If for stable on heating consideration, also can select for use pottery and glass to make base material.Use non-metallic material can produce the getable effect of metallic substance equally.

Different times, different region, client is to the hobby difference of color, and this just requires watchcase, and the tone of watchband must change to some extent with client's hobby.As change the thickness of TixOy, ZrxOy, FexNy rete, and the tone and the color and luster that just can change the matrix surface coating become rose gold etc., preparation TixOy, and ZrxOy or FexNy not only can plate out with ion, also can be with sputtering method or chemical Vapor deposition process.
