Creative embodiment is also disclosed in the specification of present patent application and the accompanying drawing.Also can limit by the alternate manner beyond the mode that limits in the follow-up claim inventive content of present patent application.Inventive content also can be comprised of several independently inventions, if especially according to clear and definite or implicit subtask or in view of the advantage that obtains or sets of advantages close examination the present invention.Because inventive concept set forth independently, some restrictions that comprise in the follow-up claim may be unnecessary.In the scope of basic inventive concept set forth, the feature of different embodiments of the invention can be applied to other embodiment.
In a kind of preferred structure, relate to the method for the cover of making electronic installation, cover comprises the substrate that is made of stainless steel, at least a portion of the section's section that is made of stainless steel is coated with the NCVM coating.
In one embodiment, the NCVM coating directly is arranged on the stainless steel.
In one embodiment, make color layers at stainless steel, and described color layers is coated with the NCVM coating.
In one embodiment, make color layers by PVD (physical vapour deposition (PVD)) method.In one embodiment, with comprising the WR4 such as Substance Substance WR
Figure BDA0000087811700000022
Raw material make the NCVM coating.
In one embodiment, the substrate that is made of stainless steel extends at cover fully, and the outer surface of substrate is coated with the NCVM coating.
Description of drawings
Some embodiments of the present invention have been described in the accompanying drawings in further detail, wherein:
Fig. 1 is the diagrammatic view of exemplary cap parts;
Fig. 2 is the schematic side-view of the cross section of exemplary cap parts; With
Fig. 3 is the diagram of illustrative methods of making the cover of electronic installation.
In the accompanying drawings, be simplified for more shown embodiment of purpose clearly.In the accompanying drawings, represent similar parts with identical Reference numeral.
Embodiment
Fig. 1 is the diagrammatic view of exemplary cap parts, and Fig. 2 is the schematic side-view of the cross section of exemplary cap parts, and Fig. 3 is the diagram of illustrative methods of making the cover of electronic installation.
Cover 1 can be the part of mobile phone, some other portable or fixed communication devices (it has the part radio function at least, such as communicator) or some other portable electron device (such as palmtop PC, portable computer, game console or controller, the transcriber that is used for the sense of hearing and/or visual material, pulse counter, code reader, razor, be used for measuring reflector and/or receiver or the analog of purpose).
Cover 1 comprises the substrate 2 that is made of stainless steel.
Substrate 2 can consist of the supporting structure of cover 1.Substrate 2 can be the structure that consists of the full depth of the cover 1 except thin NCVM coating 3.Alternatively, substrate 2 can be the one deck in the hierarchy that is constituted to small part cover 1.
Here, substrate 2 extends across cover 1 fully.According to another embodiment, substrate 2 is only in one section extension of cover 1.
Cover 1 can comprise and is not to be made of but the element and the parts that are made of other material stainless steel.Described other material can be for example metal, metal alloy, plastics or composite material.
Substrate 2 is coated with NCVM coating 3, the coating of namely making by NCVM technique.NCVM represents non-conducting vacuum plating (Non Conductive Vacuum Metallization).This represents a kind of process of surface treatment, makes thin (thickness range is generally 0.05 μ m to 0.1 μ m) coating at substrate in this technique.NCVM technique itself is well-known and therefore is not described in detail herein.
NCVM coating 3 directly is arranged on the stainless steel.Therefore do not need precoated shet.Preferably, the outer surface of substrate 2 is coated with NCVM coating 3.The outer surface here represents to be positioned at the surface in cover 1 outside.In another embodiment, two of substrate 2 surfaces all are coated with NCVM coating 3.The surface of substrate 2 can partially or completely be coated with coating.NCVM technique can utilize a large amount of raw material to prepare the NCVM coating.
According to an embodiment, raw material comprise or are the Substance WR that is produced by Merck Chemicals (Merck chemical industry) fully
