Detailed description of the invention
Unless otherwise indicated, the term used in the present invention in the specification and in the claims has following definitions.
Embodiment
Further detailed description is done to the present invention with reference to specific embodiment, but embodiments of the present invention are not limited to
This.The technology not being described further, can refer to ability conventional technical means and is implemented.
The error range of temperature is within ± 5 DEG C in following embodiments.Optical coating process uses UNIVAC E-Beam
2050 electron beam evaporation deposition machines (E-beam Evaporator).
Embodiment 1:Jewellery top layer electricity gold
When jewellery top layer electrodeposited coating is Gold plated Layer, electricity gold processing detailed process:
(i)Surface polishes, to remove the sand hole of workpiece surface, file trace.
Surface polishing is operated according to this area conventional steps, it may include fried color polishing, sanding and polishing kit
Workpiece surface is polished, the surface for making workpiece coarse becomes smooth glossy, timely and effectively to be repaired;Paraffin removal,
Repair, the fault of workpiece, defect, damage etc. are made up;Gluing(Oil);Sandblasting;Oiling(Nail polish);Removing glue, most
Electrobrightening afterwards.
(ii)Ultrasonic cleaning;Ultrasonic degreasing is the mechanical force using supersonic oscillations, makes to produce number in degreasant solution
Minute bubbles in terms of ten thousand, these minute bubbles produce strong impact power, the oil for attaching material surface when forming growth and closure
Fat, dirt depart from rapidly, so as to accelerate skimming processes, make degreasing more thorough, complex-shaped for handling, and have micropore, blind hole, narrow
Seam and degreasing require high material more effective.Using distilled water as cleaning solvent in supersonic cleaning machine, paraffin removal can be properly added
The auxiliary cleaning agents such as water.
(iii)Electrochemical degreasing, jewellery are hung on the cathode of alkaline electrolyte, are acted on using polarization of electrode when being electrolysed
The surface tension of solution interface is reduced, the bubble hydrogen and oxygen bubbles separated out on electrode, has oil lamella strong tear effect
With the mechanical agitation to solution, so that promoting oil film promptly to come off from material surface is changed into tiny oil droplet, add
Speed, strengthen oil removal process, and then obtains and almost thoroughly remove clean good deoiling effect.
By verification experimental verification, general electrolysis water temperature range is at 45 DEG C~50 DEG C, 9 V of voltage, more than 45 seconds time, clearly
Wash that effect is preferable, under particular case can root Ju clean surface degree difference, it is appropriate to adjust voltage and extend electrolysis time.Electrolysis
The time that product afterwards need to rinse is about 8 minutes~10 minutes.It is the indispensable part of electroplating technology to be rinsed with water,
The purity level of washing quality and water has for the quality index such as the stability and the appearance of electroplated product of electroplating technology, corrosion resistance
Great influence, rinsing should be thorough.
(iv)Pickling, ornaments can generate one layer of thin oxide film through oil removing, washing rear surface, can influence coating and parent metal
Bond strength, therefore, to be activated before plating, be activated usually using dilute sulfuric acid, material surface is produced slight erosion,
Expose the crystalline structure of metal, to ensure coating and base material bond strength, activating solution is generally all diluter, will not destroy material surface
Finish, it is activated after jewellery must wash again, electroplated again after clean.
Electricity gold is activated using 5% dilute sulfuric acid aqueous solution in the present embodiment, is soaked 3 seconds~5 seconds, the head crossed after pickling
Decorations are clean using distilled water flushing.
(v)Electric gold, in temperature range at 45 DEG C~50 DEG C, voltage is the V of 2.5 V~2.8 in electric Jinsui River, 20 seconds time~
45 seconds.
The collocation method in electric Jinsui River, is allocated or is directly bought the electricity gold prepared according to the quality of the layer gold to be plated
Water.Such as the electric Jinsui River of Europe Memec 24K gold is used in the present embodiment.
The results show, in the same circumstances, the temperature in Jinsui River can influence jewellery surface gold plate during electricity gold
Color, temperature is relatively low, then color is shinny, conversely, temperature drift, then color is partially white.Therefore, color adaptation that can be as needed is electric
Pressure and time, such as:When gold-plated again, the electricity gold time can suitably shorten, such as the secondary electric golden electricity golden time was at 20 seconds or so.
(vi)Using pure water or distilled water, clean up and dry up, that is, obtain the gold-plated jewellery in top layer.
Overlay coating processing technology in the present invention is suitable for coating as common Plating Ornaments such as gold, silver, rhodiums, this sentences plating
Exemplified by layer gold, treatment technique is verified using the sample prepared by embodiment 1 as experimental products.
