Abstract
The utility model relates to a metal plating field specifically discloses a compound plating layer structure of decorative trivalent chromium chromium plating. The utility model discloses a compound plating layer structure of decorative trivalent chromium chromium plating, including metal substrate and plating layer, metal substrate is the 1Cr13 stainless steel, the plating layer does chloride trivalent chromium chromium -plated layer, sulphate trivalent chromium chromium -plated layer that metal substrate plated on the surface in proper order. The utility model discloses plating a surperficial no corrosion product and generating, the corrosion resistance satisfies the technical requirement of cell -phone accessory.
Description
Technical field
The utility model relates to Metal plating field, is specifically related to a kind of composite plating layer structure of ornamental trivalent chromium chrome plating.
Background technology
Highly toxic hexavalent chromium plating is replaced to become the inexorable trend of electroplating industry development with environment-friendlytrivalent trivalent chromium electroplating technology.Trivalent chromium plating comprises muriate and vitriol two individual system, and two kinds of techniques respectively have relative merits.Muriate trivalent chromium chrome plating layer is close to stainless color and luster, and decorative effect is poor, is generally used for mid and low-end products electroplated decorative chromium, sulfate trivalent chromium chromium coating bright color, outward appearance is similar to sexavalent chrome chromium coating, and solidity to corrosion is better, is generally used for mid-to high-end product decorative electroplating.The thickness of muriate trivalent chromium chrome plating layer still can keep light when reaching 0.5 μm, can prepare thicker coating, and sulfate trivalent chromium chromium coating more than 0.2 μm time just easily send out mist, thinner coating can only be prepared.
Some spare and accessory parts of mobile phone need trivalent chromium plating decorative chromium, and general requirement adopts sulfate trivalent chromium chromium plating.The skin of nickel to some has anaphylaxis, therefore, does not generally adopt nickel layer in design, and even metallic matrix also requires not containing nickel element.Adopt the stainless materials such as not nickeliferous 1Cr13 can meet above-mentioned requirements, but the stainless solidity to corrosion of 1Cr13 is poor, needs thicker trivalent chromium chrome plating layer protection could meet the technical requirements of mobile phone spare and accessory parts.Independent employing muriate trivalent chromium chrome plating, its outward appearance and solidity to corrosion all can not be satisfactory, are used alone sulfate trivalent chromium chromium plating, and thickness of coating is difficult to again meet the demands.
Utility model content
In view of this, be necessary for above-mentioned problem, a kind of composite plating layer structure of ornamental trivalent chromium chrome plating is provided.Composite plating layer structure of the present utility model, can meet thickness requirement and the cosmetic requirement of coating simultaneously.
For achieving the above object, the utility model adopts following technical scheme:
The composite plating layer structure of ornamental trivalent chromium chrome plating of the present utility model, comprises metallic matrix and electrolytic coating; Described metallic matrix is 1Cr13 stainless steel; Described electrolytic coating is the muriate trivalent chromium chrome plating layer, the sulfate trivalent chromium chromium coating that plate successively on described metal base surface.
Preferably, the thickness of described muriate trivalent chromium chrome plating layer is 0.3 ~ 0.5 μm.
Preferably, the thickness of described sulfate trivalent chromium chromium coating is 0.1 ~ 0.2 μm.
The beneficial effects of the utility model are:
The composite plating layer structure of the ornamental trivalent chromium chrome plating that the utility model provides, Direct Electroplating muriate trivalent chromium chrome plating layer on 1Cr13 stainless steel base, and then plate sulfate trivalent chromium chromium coating, the corrosion-free product in the new plating piece surface of this practicality generates, and solidity to corrosion meets the technical requirements of Cellphone Accessories.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the composite plating layer structure of the ornamental trivalent chromium chrome plating of the utility model.
Embodiment
Describe the utility model in detail below in conjunction with accompanying drawing and specific embodiment, be used for explaining the utility model in this illustrative examples of the present utility model and explanation, but not as to restriction of the present utility model.
Embodiment 1:
As shown in Figure 1, a kind of composite plating layer structure of ornamental trivalent chromium chrome plating, comprises 1Cr13 stainless steel base 1, electroplates the muriate trivalent chromium chrome plating layer 2 on 1Cr13 stainless steel base 1 and sulfate trivalent chromium chromium coating 3 successively.
Described muriate trivalent chromium chrome plating layer 2 adopts the Trich-6561 muriate trivalent chromium chrome plating technique of Guangzhou Chao Bang Chemical Co., Ltd. to prepare, and thickness of coating is 0.3 ~ 0.4 μm.
Described sulfate trivalent chromium chromium coating adopts the Trich-9551 trivalent chromium sulfate plating process preparation of Guangzhou Chao Bang Chemical Co., Ltd., and thickness of coating is 0.1 ~ 0.2 μm.
The present embodiment is divided into following steps in concrete operations:
Step 1, pre-treatment: operation process 1Cr13 stainless steel base 1 being carried out successively to " the sulfuric acid catholyte activation → washing of alkali electroless oil removing → washing → alkaline anode electrolysis oil removing → washing → pickling → washing → 10% ".
Step 2, muriate trivalent chromium chrome plating layer 2:1Cr13 stainless steel base 1 carry out Direct Electroplating muriate trivalent chromium chrome plating layer 2 after pre-treatment.
Step 3, sulfate trivalent chromium chromium coating 3: muriate trivalent chromium chrome plating layer 2 washes rear Direct Electroplating sulfate trivalent chromium chromium coating 3, then washes, dry, inspection, packaging.
Production test proves, stainless steel base, after the step 1 described in the present embodiment processes, directly can carry out trivalent chromium chrome plating.Electroplate identical to the activating mechanism of stainless steel base with impact nickel during trivalent chromium chrome plating solutions.Plating piece prepared by the present embodiment carries out neutral salt spray test 76h according to GB/T10125 – 1997 " artificial atmosphere corrosion test salt-fog test ", and the corrosion-free product in plating piece surface generates, and solidity to corrosion meets the technical requirements of Cellphone Accessories.Type composite deposite had both overcome the not high shortcoming of muriate trivalent chromium chrome plating layer visual appearance, overcame again the shortcoming of sulfate trivalent chromium chromium coating thickness deficiency.
The above embodiment only have expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
Claims (3)
