When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
The technical scheme provided by the embodiment of the disclosure relates to a surface treatment process of metal or alloy, in particular to a surface treatment process of active metal and alloy thereof which are easy to oxidize, such as magnesium alloy or aluminum alloy. In the related art, in order to ensure the aesthetic appearance of the mobile phone exterior part, the mobile phone exterior part processed from metal such as aluminum alloy is subjected to polishing treatment and anodic oxidation treatment. However, during the period from the end of the polishing treatment to the start of the anodic oxidation treatment, the aluminum alloy is stored in the industrial pure water, and since a certain potential difference exists between the doped metals such as copper, manganese, zinc and the like in the aluminum alloy and the metal aluminum, and the industrial pure water inevitably contains some impurity ions which can serve as an electrolyte, a micro-battery system is formed in the aluminum alloy, and further, the formation of corrosion pits, i.e., pits, is caused by electrochemical reaction. After the anodic oxidation treatment, pockmarks appear on the surface of the mobile phone appearance piece, and the higher the surface smoothness of the mobile phone appearance piece is, the more serious the pockmarks are.
Based on this, the technical scheme provided by the embodiment of the present disclosure forms a protective film on the surface of the alloy body after polishing treatment to inhibit the alloy body from micro-battery corrosion, cleans the protective film when the alloy body needs to be anodized, and then anodizes the cleaned alloy body to form a desired oxide film on the surface of the alloy body. Therefore, the protective film can block the contact of external corrosive substances and the alloy body, so that the micro-battery corrosion formed in the alloy body can be effectively prevented in the time period from the polishing treatment to the anodic oxidation treatment, the formation of corrosion pits, namely pockmarks, is avoided, and the appearance texture of the alloy body is ensured. Furthermore, the obvious reduction of the number of the corrosion pits can also ensure the continuity and the integrity of the oxide film formed by anodic oxidation treatment, and because the oxide film not only can improve the surface hardness of the alloy body, but also can prevent the further oxidation of the alloy body, the technical scheme can also improve the wear resistance and the corrosion resistance of the alloy body.
Fig. 1 illustrates a flowchart of a surface treatment method provided by an embodiment of the present disclosure. The surface treatment method can be applied to the surface treatment of terminal appearance parts such as mobile phone metal outer frames. As can be seen from fig. 1, the surface treatment method specifically includes the following steps S101 to S103:
s101, polishing the surface of the alloy body.
The alloy body is an alloy member made of an alloy material of an active metal such as an aluminum alloy or a magnesium alloy, and particularly is a metal outer frame of an appearance member such as a mobile phone. The polishing treatment refers to a treatment process of polishing and grinding the surface of the alloy body to improve the surface glossiness of the alloy body, and the polishing treatment can specifically adopt an oil polishing mode or a wax polishing mode, and the disclosure does not limit the polishing treatment.
And S102, forming a protective film on the surface of the polished alloy body, wherein the protective film is used for inhibiting the micro-battery corrosion of the alloy body.
The protective film is a thin film formed on the surface of the alloy body and capable of inhibiting corrosion of the alloy body, and may be formed by coating or soaking, and the embodiment of the present disclosure is not limited thereto.
S103, cleaning the protective film on the surface of the alloy body, and carrying out anodic oxidation treatment on the cleaned alloy body to form an oxide film on the surface of the alloy body.
The anodic oxidation treatment is an electrochemical oxidation treatment performed on the alloy body in a specific electrolyte environment, and as a result of the treatment, a metal oxide thin film is formed on the surface of the alloy body, and the oxide thin film can increase the surface hardness of the alloy body and prevent further oxidation.
Based on this, the surface treatment method provided by the embodiment of the disclosure is to form a protective film on the surface of the alloy body after polishing treatment to inhibit the alloy body from micro-battery corrosion, clean the protective film when the alloy body needs to be anodized, and then perform anodization treatment on the cleaned alloy body to form a required oxide film on the surface of the alloy body. Therefore, the protective film can block the contact of external corrosive substances and the alloy body, so that the micro-battery corrosion formed in the alloy body can be effectively prevented in the time period from the polishing treatment to the anodic oxidation treatment, the formation of corrosion pits, namely pockmarks, is avoided, and the appearance texture of the alloy body is ensured. Furthermore, the obvious reduction of the number of the corrosion pits can also ensure the continuity and the integrity of the oxide film formed by anodic oxidation treatment, and because the oxide film not only can improve the surface hardness of the alloy body, but also can prevent the further oxidation of the alloy body, the technical scheme can also improve the wear resistance and the corrosion resistance of the alloy body.
In this example embodiment, the alloy body includes a magnesium alloy body or an aluminum alloy body, but is not limited thereto. Wherein, the aluminum alloy body can comprise any one of high-strength aluminum alloys such as a copper aluminum alloy body, a manganese aluminum alloy body, a zinc aluminum alloy body and the like; similarly, the magnesium alloy body may include any one of high-strength magnesium alloys such as a copper magnesium alloy body, a manganese magnesium alloy body, and a zinc magnesium alloy body. It should be understood that the embodiments of the present disclosure are not limited to the constituent elements in the alloy body, and any active metal or alloy that is suitable for the end-use appearance member and is easily oxidized is within the protection scope of the present disclosure.
Optionally, in this embodiment, a specific method for performing polishing treatment on the surface of the alloy body includes: and carrying out mechanical chemical polishing treatment on the surface of the alloy body so as to enable the surface roughness Ra of the alloy body to reach at least 3.2, for example, to reach 0.8-3.2, wherein when the roughness Ra reaches 0.8, the alloy surface can obtain a highlight effect. From this, it is found that the lower the value of the surface roughness Ra, the more easily the surface of the alloy body becomes a bright mirror surface effect. Of course, in this embodiment, the surface of the alloy body may be subjected to a common polishing process, and the polished surface of the alloy body may be further subjected to a sand blasting process to form a frosted surface. For example, when the surface of the alloy body is polished, a polishing solution containing miraculone 310(CIMTECH 310) can be used to ensure the lubricity, cooling property and the like of the polishing process, wherein the volume ratio of the miraculone 310 is 4-20%. It should be noted that: mirakelon 310 is a metal working fluid manufactured by CIMCOOL (new america). Because the common polishing solution can be used as an electrolyte to form a micro-battery system with two metals with different potentials in the alloy body, the defects of pockmarks and the like on the surface of the alloy body can be caused by electrochemical reaction in the polishing process of the alloy body, and the embodiment can form a protective film on the surface of the alloy body by adding the milakron 310 into the common polishing solution, thereby playing the role of preventing the alloy body from being oxidized, changing the properties of the polishing solution, damaging the forming condition of the micro-battery system and achieving the effect of preventing the pockmarks. It should be noted that: in this embodiment, edible oil containing oily organic matter, such as peanut oil or rapeseed oil, may be added to the polishing liquid, and the addition is not particularly limited as long as the polishing effect of the surface of the alloy body can be improved.
Alternatively, a method for forming a protective film on the surface of the alloy body after polishing treatment in the embodiment may include: and soaking the polished alloy body in a target solution containing an anti-corrosion agent to form a protective film on the surface of the alloy body. For example, the target solution may be a solution containing melagatran 310, wherein the volume percentage of melagatran 310 may be set to greater than or equal to 50%. It should be noted that: the step of forming the protective film on the surface of the alloy body needs to be performed as soon as possible after the polishing process is finished, so as to prevent the alloy body from being exposed to air to form pits. Therefore, in the period from the end of the polishing treatment to the start of the anodic oxidation treatment, the alloy body is kept in the target solution containing the milnacron 310, so that the effect of isolating the external environment is achieved on the alloy body, and the defects of pockmarks and the like caused by electrochemical reaction are avoided.
Optionally, another method for forming a protective film on the surface of the alloy body after polishing in this embodiment includes: and soaking the polished alloy body in an organic solution containing oily organic matters to form a protective film on the surface of the alloy body. For example, the organic solution may be an organic solution containing an edible oil such as rapeseed oil or peanut oil, wherein the volume percentage of the edible oil may be determined according to actual needs. It should be noted that: the step of forming the protective film on the surface of the alloy body needs to be performed as soon as possible after the polishing process is finished, so as to prevent the alloy body from being exposed to air to form pits. In this way, the alloy body is kept in the organic solution containing the oily organic matter in the period from the finishing of the polishing treatment to the beginning of the anodic oxidation treatment, so that the alloy body can be isolated from the external environment, and defects such as pits and the like caused by electrochemical reaction are avoided.
Optionally, in this embodiment, the specific method for cleaning the protective film on the surface of the alloy body and performing anodic oxidation treatment on the cleaned alloy body includes: and cleaning the alloy body coated with the protective film by using pure water or alkalescent water, and then carrying out anodic oxidation treatment on the cleaned alloy body. For example, the electrolyte for the anodic oxidation treatment can be a sulfuric acid solution, the anode can be an alloy body, the cathode can be a lead rod or a carbon rod, and after the electrochemical oxidation treatment, an oxide film can be formed on the surface of the alloy body, and the hardness of the oxide film is higher than that of the alloy body, so that the alloy body can be protected to a certain extent, and further oxidation of the alloy body can be prevented.
The surface treatment method provided in this embodiment is described in detail below by taking a mobile phone case made of copper-aluminum alloy as an example. Specifically, the outer frame of the machined copper-aluminum alloy can be cleaned, for example, by degreasing, alkali washing and acid washing; then, polishing liquid containing Miraberon 310 is used for carrying out mechanical chemical polishing treatment on the cleaned copper-aluminum alloy outer frame so as to improve the surface glossiness of the copper-aluminum alloy outer frame, wherein the volume percentage of the Miraberon 310 is 10%, the polishing liquid can ensure the lubricity and the cooling property in the polishing process, and the corrosion of the polishing liquid to the inside of the copper-aluminum alloy can be weakened by adding the Miraberon 310, so that a micro-battery system cannot be formed between doped metal copper and metal aluminum in the copper-aluminum alloy, and the formation of pockmarks is avoided; then, the polished copper-aluminum alloy outer frame can be soaked in a target solution containing a Miracolon 310 so as to form a protective film on the surface of the copper-aluminum alloy outer frame, wherein the volume percentage of the Miracolon 310 is 80 percent, and the protective film can prevent external corrosive substances from contacting with the copper-aluminum alloy, so that pocking marks caused by the corrosion of a micro battery can be avoided; and then, the copper-aluminum alloy outer frame covered with the protective film can be cleaned by using weak alkaline water, and the cleaned copper-aluminum alloy outer frame is subjected to anodic oxidation treatment, so that an aluminum oxide film can be formed on the surface of the copper-aluminum alloy outer frame, the aluminum oxide film can be used as a hard protective film of the copper-aluminum alloy outer frame, and meanwhile, the copper-aluminum alloy can be prevented from being further oxidized, so that the wear resistance and the corrosion resistance of the copper-aluminum alloy outer frame can be improved. In the related art, in order to reduce the probability of forming pockmarks, the polished aluminum alloy needs to be soaked in industrial pure water with the conductivity of less than 1%, and meanwhile, the aluminum alloy needs to be subjected to anodic oxidation treatment within 2 hours. However, considering that industrial pure water inevitably contains some impurity ions, and chlorine ions and the like in the air are dissolved in industrial pure water, the time control of the field production is not so precise, and thus the formation condition of the pits is easily formed in the actual production. In the embodiment, the polished alloy part is stored by adopting the target solution containing the milarone 310 instead of industrial pure water, so that the limitation of the waiting time of anodic oxidation treatment can be broken through, the defect rate is remarkably reduced from 27% to below 3%, and a feasible path is provided for realizing a high-light anodic oxidation film of the high-strength aluminum alloy.
Based on the above process, as shown in fig. 2, the surface treatment method provided by the embodiment of the present disclosure may further include the following steps S104 to S105:
and S104, coloring the alloy body after the anodic oxidation treatment.
The coloring technique of the alloy anodic oxide film can be divided into chemical coloring and electrolytic coloring, and the essence of the electrolytic coloring is electrochemical treatment, which can be performed simultaneously with the anodic oxidation treatment or after the anodic oxidation treatment. The oxide film on the surface of the alloy body can obtain good decorative effect after coloring treatment, and also has good corrosion resistance and wear resistance.
And S105, carrying out hole sealing treatment on the colored alloy body.
The sealing treatment is to seal the micropores in the colored oxide film so that the surface of the oxide film becomes uniform and dense. The hole sealing treatment in this embodiment may adopt any one of hydrated hole sealing, inorganic salt solution hole sealing, and transparent organic coating hole sealing, and details about a specific implementation process of the hole sealing treatment are not repeated in this embodiment.
Based on the surface treatment method, the embodiment of the disclosure also provides a terminal appearance piece, and the terminal appearance piece can be subjected to surface treatment by adopting the surface treatment method, so that the defects of pockmarks and the like on the surface of the appearance piece are avoided, and the beauty, the wear resistance and the corrosion resistance of the terminal appearance piece are ensured.
Other embodiments of the disclosure will be apparent to those skilled in the art from consideration of the specification and practice of the disclosure disclosed herein. This application is intended to cover any variations, uses, or adaptations of the disclosure following, in general, the principles of the disclosure and including such departures from the present disclosure as come within known or customary practice within the art to which the disclosure pertains.
