Description
The present invention relates to clock and watch with adorning part outward.
In prior art, as the outer dress part of clock and watch, for example clock and watch are with the method for surface finish of shell, and general to adopt in the occasion that is processed into white, at background be that brass or stainless surface impose Ni coating, and the method that further imposes Pd coating thereon; Impose the method for Au alloy layer being processed on the occasion of gold, the Ni coating, thereby obtain surface gloss processing effect separately on the surface of brass background.
Yet in recent years for as casing for clock and watch and the watchband of clock and watch with outer dress part, people begin to like to have the well-worn stainless steel colored or golden the sort of sensation of the outmoded sensation of pseudo-classic style.And to make it to produce such sensation by electroplating with surface-treated, past almost is impossibility, thereby, generally adopt and carry out uneven honing on the casing for clock and watch surface, and impose Ni coating thereon, impose Pd coating or Au alloy layer more thereon, so as to showing pseudo-classic style as prime coat.
But, when adopting this method, the honing lines can appear in the surface, and can not produce the sort of because of going up the scar sensation that stainless steel or gold had such, that slightly dark dull colour is transferred with old arbitrarily drawing.In addition, once imagination was carried out the gimmick that honing is handled after being used in end plating, but can eliminate prime coat simply because of handling through honing, so that thickness of coating must be made is common more than 2 times, otherwise can not get effect, also had the high problem of cost for this reason.
Inventors of the present invention study hardy for solving these the problems of the prior art, and the result has successfully obtained to give the tone of clock and watch with the outmoded sensation of the simple and unsophisticated sentiment of outer dress part, thereby has finished the present invention.
The present invention proposes clock and watch and adorn with part and manufacture method thereof, and want to address the above problem with this with outer.The clock and watch that proposed are with adorning being characterized as with part outward, have on the surface on the matrix of Ni coating and Au coating, the background of aldary or with execute by the zinc of corrosion-resistant coating as the clock and watch of background with adorn outward have on the piece surface Ni coating and thereon by at least a precious metal plating of forming in Pd, Rh, Au, the Au alloy, the coating gross thickness of above-mentioned Ni coating and above-mentioned precious metal plating is 2-5 μ m, and the relative reflectance on film surface is 4-7.
Below, to be elaborated with outer dress part to clock and watch with regard to the clock and watch housing, the present invention is to be purpose with the clock and watch shell that obtains to have broken away from original gloss outmoded sensation processing, that can give pseudo-classic style, reaches by thinking that in the past the plate surface that can not realize this purpose is handled.
The background of casing for clock and watch of the present invention etc. is for the brass or the packfong of the aldary identical with prior art or impose the zinc of corrosion-resistant coating on the surface, impose Ni coating as prime coat, on this layer, make it to form any simple layer or composite bed in Pd coating, Rh coating, Au coating and the Au alloy layer of precious metal plating.The Pd that this occasion adopted, Rh, Au, Au alloy can be in the plating of prior art adopt.
The thickness of coating comprises prime coat and precious metal plating, serves as suitably with 2-5 μ m, even if precious metal plating is not an individual layer, also is necessary in this scope.Outside this scope, can not obtain the tonal effect that the present invention pursues with pseudo-classic style.In addition, its thickness when 2 μ m are following, its corrosion resistance generation problem; Its thickness then produces the problem on the cost again when 5 μ m are above.
For the processing of casing for clock and watch overlay coating, can answer required tone to do all changes.For example, when needing semi-glossy tone white, at the bottom of the brass copy for the record or for reproduction, impose lacklustre Ni coating, and impose glossiness Pd coating thereon; When needs gold look, on lacklustre Ni coating, impose glossiness Au alloy layer; Perhaps, the matt Ni coating in preceding note imposes glossiness Au alloy layer; Superpose on the matt Ni coating of note before also can be used on and electroplate and glossiness Au alloy layer with glossiness Pd.The method that various combinations are arranged in a word might not make all become matt plating.Matt Ni described herein electroplates, and is meant that polishing material that use will cooperate is limited to the occasion of normally used electrobath about half.And glossy Pd plating, glossy Au alloy plating etc. are meant the occasion of the electrobath that has used common generation gloss.
As polishing material, can exemplify to having=C-SO
2Benzoic sulfimide, 1,5 naphthalene disulfonate, 1,3 of structure, polishing materials such as 6 naphthalene trisulfonic acid sodium reach coumarin, 2-butine, 2-butine-1, secondary polishing materials such as 4-glycol, ethylene cyanohydrin, thio urea, quinoline, pyridine.
Among the present invention, in the tarnish of using Pd, Rh, Au, Au alloy electroplates, be necessary to adopt these polishing materials are adjusted to electrobath in common about 1/2nd the scope.
Crucial part is among the present invention, the full thickness of coating is adjusted in the scope of 2-5 μ m, and the use level of the polishing material by the plus-minus electrobath, make the relative reflectance on film surface remain in the 4-7 scope.The said relative reflectance of the present invention is meant, the surface has the thick gloss Ni coating of 1 μ m that forms with the gloss Ni electrobath described in the embodiment 2, and the copper alloy plate (the no scar in surface) of the thick gloss Pd coating of the 2 μ m that form with the described gloss Pd electrobath of embodiment 1 at this gloss Ni coating surface is as standard jig, with automatic goniophotometer (color technical institute system in the village), to be set at 10 for the normal reflection rate of 60 ° of incident angles of the coating surface of standard jig, then sample is a relative reflectance for the reflectivity of this standard jig.Also promptly, the said relative reflectance of the present invention promptly refers to establish after the normal reflection rate is 10 with standard jig, thereby adorns the numerical value that the angle luminosity curve of 60 ° of reflection of incident light directions of the coating surface of part obtains outward with the clock face that the application's method is handled.Even the clock and watch of prior art with the coating of shell for semi-glossy accent (thing of honing processing) also more than 9, so the scope of relative reflectance 4-7 of the present invention be in the past can't realize.
