Only 22% of the weight of iron and 66% of the weight of aluminum is accounted for by magnesium. In addition, magnesium alloy possesses the highest relative strength, and its specific stiffness is comparable to that of aluminum alloy and steel, which is significantly greater than that of engineering plastics. Magnesium alloy can be cast into a wide variety of shapes and sizes.
Even though the effect on weight loss is significantly improved, the rate at which magnesium alloys are being produced has slowed down. The corrosion of magnesium alloys, the development of low-cost and high-performance magnesium alloys, the connection of magnesium alloys with dissimilar materials, the high rejection rate of magnesium alloy die-casting parts, and the poor deformation and processing of magnesium alloys are currently the difficulties that are restricting the mass application of magnesium alloys.. However, it should be noted that early design and process optimization can already reduce costs by working closely with automobile manufacturers. This is something that has been brought to people's attention.
Despite the fact that there are still some issues that need to be resolved, the application prospect of magnesium alloys in the field of automotive manufacturing is still promising. The Technical Roadmap for Energy Saving and New Energy Vehicles sets the target consumption of magnesium alloy in bicycles in 2030 at 45 kg. This number was determined based on the roadmap. There is no online cnc machining service limit to the potential. In the not too distant future, magnesium alloy will be widely used in the production of steering supports and seat frames.
One of the most promising developments in the realm of lightweight materials for automobiles is magnesium alloy.
Recently, there has been an increase in demand for a process known as electroplating, which gives the surface of magnesium alloys a metallic appearance. In the present day, the electroplating method or the vacuum evaporation method will typically first adsorb Pd catalyst onto the coating film, and then they will perform electroless plating, etc. The primary reason for this is that galvanic corrosion is quite likely to take place, and the film that is precipitated during the electrolysis process covers the magnesium substrate. This, in turn, makes corrosion more likely to advance. The first method is known as the Dow method, and the second method is known as the Sakata method. Both require a number of different pretreatments, and the treatment solution can contain dangerous chemicals like chromate, fluoride, and cyanide. Additionally, there are issues with the adhesion and corrosion resistance of the electroplating film.
The conductive anodic oxide film has the capability of being energized, and it also has the capability of being directly electroplated as a base for electroplating. A film with superior resistance to corrosion and adhesion can be obtained through the use of a straightforward process. This part of the article explains the process of electroplating pretreatment of anodized film with electrical conductivity, which is entirely unique in comparison to processes used in the past. It does not make use of any potentially hazardous components, such as chromium hexavalent, and it does not require any complicated pretreatment. The method is making strides toward becoming more applicable in real life. The most recent developments in the surface treatment of magnesium alloys, as well as custom cnc milling some new phosphate-based anodizing treatments and some application examples, are discussed in this article.
The demand for applications that are primarily utilized in the housings of portable electronic instruments is gradually growing and is driving the gradual increase in the demand for magnesium alloys. In addition, as a lightweight material, its application is anticipated to increase significantly in the field of transportation machines, where it is anticipated that its use will also increase significantly. Shenzhen Huiwen Zhizao Technology Co. , Ltd. The anodizing treatment that is discussed in this article satisfies all environmental protection standards and possesses unprecedented levels of corrosion resistance as well as film conductivity. Additionally, the treatment does not involve the utilization of any harmful substances or heavy metals such as chromium. An important technological advancement that will increase the demand for magnesium alloys. In this way, the chemical reaction of the electrochemical reaction will easily cause defects in the defect parts of the material that has many defects. This will have an effect on the online cnc machining service corrosion resistance and conductivity of the material. Photos taken by a scanning electron microscope (SEM) of the surface and cross-section of the newly developed conductive anodic oxide film are displayed in Figure 7. The conductivity of the film can be attributed to the fact that the oxide film is predominantly made up of MgO and that a composite oxide film that has been doped with phosphorus and aluminum is formed.
The surface resistance value can vary depending on the grade, but it typically has a low value in the range of 0. 1 to 0. 6 online milling service ohms. Because this treatment does not make use of potentially harmful substances like fluorine compounds or heavy metals like chromium or manganese, it is considered to be an effective treatment method for the protection of the environment. The fact that the film has a glassy appearance is indicated by the HaloPattern that is produced by the selected area diffraction pattern of the film, and the XRD test does not reveal any diffraction peaks that are produced by the film itself. As a result of this, it is reasonable to assume that conductivity is closely related, not only to the chemical composition that constitutes the film, but also to the structure of the film itself.
