“…This enhances the use of energy and materials and minimizes the impact of businesses on the natural environment by reducing the volume of waste to be recycled and utilized. In order to increase productivity and reduce costs in magnesium wheel production, Dewei Technology and Dingxin Magnesium have built a production line for a one-step forming process, in which the billet is heated once, and only one set of dies is used to form the wheel forging [70]. Other promising magnesium wheel-forming technologies include backward extrusion, which is low-waste and enables the energy required to manufacture the semi-finished product to be reduced.…”

This article provides a detailed review of the types of magnesium wheels available in the industry and the current methods of the wheels’ production. The past several years have seen a significant development of magnesium-based lightweight alloys employed as a structural material for modern light vehicles. Magnesium alloys are characterized by their low density while maintaining good mechanical properties. The use of these alloys in the industry enables vehicles’ weight reduction while increasing their technical parameters. The first part of the article presents the unique properties of magnesium alloys that determine the application of this material for lightweight vehicle wheels. The advantages of using magnesium wheels over aluminum wheels are also presented. Next, a classification of the types of magnesium wheels was made in regard to their construction, applications, and manufacturing methods. At present, magnesium wheels by construction can be classified according to their geometry as single parts or assembled parts. In reference to geometry, wheels can have different shapes: classic, multi-spoke, with holes, or with frames. Depending on the geometry used, magnesium wheels can have different parameters, such as their mounting hole spacing, wheel diameters, or rim width. Considering the applications in various industries, main distinctions can be made between magnesium wheels for automobiles, motorcycles, bicycles, and wheelchairs. Magnesium wheels can also be categorized in regards to the manufacturing methods: casting, machining, forging, and hybrid manufacturing. The second part of the article focuses on the analysis of magnesium alloy wheel-manufacturing technologies used in the industry and developed by research centers. This article discusses these manufacturing technologies in detail and indicates prospective directions for further development.

“…Although the above methods can obtain connecting rods with high dimensional accuracy and qualified mechanical properties, these methods have some shortcomings as follows. The forging force for the hot-forging process is large, requiring special large equipment and high equipment costs [27]. The die-casting process is prone to shrinkage porosity, shrinkage cavity, insufficient filling, and other defects within the connecting rod.…”

As an important piece of equipment for hydrogen energy application, the hydrogen internal combustion engine is helpful for the realization of zero carbon emissions, where the aluminum connecting rod is one of the key core components. A semi-solid forging forming process for the 7075 aluminum alloy connecting rod is proposed in this work. The influence of process parameters, such as the forging ratio, sustaining temperature, and duration time, on the microstructures of the semi-solid blank is experimentally investigated. The macroscopic morphology, metallographic structure, and physical properties of the connecting-rod parts are analyzed. Reasonable process parameters for preparing the semi-solid blank are obtained from the experimental results. Under the reasonable parameters, the average grain size is 41.48~42.57 μm, and the average shape factor is 0.80~0.81. The yield strength and tensile strength improvement ratio of the connecting rod produced by the proposed process are 47.07% and 20.89%, respectively.

Due to a number of unique properties, magnesium and its alloys are attractive for use in mechanical engineering, medicine, aviation, the automotive industry, etc. Unfortunately, the widespread use of these materials is limited by their low corrosion resistance. Traditional surface modification techniques have struggled to simultaneously enhance both the mechanical durability and corrosion resistance of magnesium‐based materials. Herein, a method synergistically combining the advantages of arc spraying, laser processing, and hydrophobization is developed. This finely tuned combination results in the production of an aluminum coating with superhydrophobic properties formed on top of magnesium alloy that has very high mechanical and chemical resistance. The results presented in this article demonstrate that such coatings preserve a constant contact angle exceeding 165° during a year of laboratory storage, withstand long‐lasting humid and salt fog atmosphere, demonstrate corrosion current lower than 3 × 10−8 A cm−2 during 120 days of its continuous contact with chloride‐containing corrosive environments, and preserve the superhydrophobic state after sand abrasion test. The corrosion inhibition mechanisms of the designed coating are discussed. The developed innovative approach addresses a critical challenge in enhancing the corrosion resistance of magnesium‐based materials, paving the way for their broader application across various industrial sectors.
