Abstract
The present invention relates to clock and watch with adorning part outward.
The present invention proposes clock and watch adorns with part and manufacture method thereof with outer, the clock and watch that proposed are with adorning being characterized as with part outward, have on as the same alloy of background or Ni coating of executing on the corrosion-resistant coating of zinc and the coating that has noble metal a kind of in Pd, Rh, Au, the Au alloy at least thereon, holostrome is thick to be that 2-5 μ m, relative reflectance are 4-7.The clock and watch that are processed into method of the present invention are adorned part outward and are had simple and unsophisticated natural, graceful and poised generous style.
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, general employing is that brass or stainless surface impose Ni coating in the occasion that is processed into white, at background, and further impose the method for 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 carry out on the casing for clock and watch surface uneven honing, and impose thereon Ni coating as prime coat,, impose Pd coating or Au alloy layer more thereon, so as to showing pseudo-classic style.
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 to solve 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 as the same alloy of background or Ni coating of executing on the corrosion-resistant coating of zinc and the coating that has noble metal a kind of in Pd, Rh, Au, the Au alloy at least thereon, golden bed thickness is that 2-5 μ m, relative reflectance are 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 same alloy 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 by this scope.Outside this scope, can not obtain the tonal effect that the present invention pursues with pseudo-classic style.
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, on 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 of preceding note impose glossiness Au alloy layer, also can be used on before on the matt Ni coating of note stack 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
2The benzoic sulfimide, 1 of structure, 5 naphthalene disulfonates, 1,3, 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.
In 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 described relative reflectance of this occasion is meant and adopts automatic goniophotometer (color technical institute system in the village) from the numerical value for the angle luminosity curve gained of the normal reflection direction of 60 ° of incident lights of coating surface, 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.
Fig. 1 represents coating of the present invention, reaches the angle luminosity curve of the Pd coating surface of art methods with automatic goniophotometer (GP-1R) mensuration, and A, B, C are respectively the curve of present embodiment 1,2,3, and D is the curve of art methods.Hence one can see that, and product rough surface of the present invention shows a kind of semilustrous feeling of high class that has.
According to the present invention, remain in the scope of 4-7 by relative reflectance with coating film surface, thus obtained to see through each coating light surface preparation that interfere mutually, prior art the casing for clock and watch of generous simple and unsophisticated style that can't obtain, that have feeling of high class, natural, graceful and poised.
Below exemplify embodiments of the invention, but the present invention is not so limited.
