New energy automobiles are an important industry that will make up an increasing proportion of future developments. The performance of its core component, forgings, will impact the safety and economy of vehicles. This article explores the factors affecting the performance of forgings for new energy vehicles from the perspectives of national policies and actual production, with specific examples.
From the perspective of national policies, the Chinese government has established regulations on the performance of forgings for new energy vehicles. For example, “Forged Aluminum Alloy Parts for New Energy Vehicles” (GB/T 32237-2015) specifies the mechanical performance testing methods, hydrogen embrittlement tests, stress corrosion tests, magnetic particle inspections, and peeling tests of forgings. “Technical Exchange and Application of New Materials Processing for Automobiles” points out that the main indicators of the performance of forgings for new energy vehicles include mechanical properties, plastic deformation capacity, microstructure, hardness, and corrosion resistance. Therefore, government standards and industry regulations have been established concerning the material selection, production process, and testing methods of forgings to ensure their performance and reliability.
In actual production, there are many complex factors affecting the performance of forgings for new energy vehicles, with the most prominent being material quality. Different materials used in forgings for new energy vehicles have different performance characteristics and economic costs. For example, aluminum alloy forgings have the characteristics of low density and strong corrosion resistance, but their wear resistance and tensile strength are relatively poor. In contrast, titanium alloy forgings have the advantages of low density, high strength, and good corrosion resistance, but they have higher production costs. Therefore, in actual production, it is necessary to make reasonable choices based on specific situations and strengthen the monitoring of material quality.
Secondly, the manufacturing process can also affect forging performance. Different manufacturing processes may result in different porosity and defect rates, which directly affect the strength and toughness of forgings. Therefore, in actual production, it is necessary to optimize the manufacturing process, adopt advanced CNC equipment and intelligent production lines, and reduce defect rates and waste.
Overall, the performance of forgings for new energy vehicles is affected by multiple factors, and government regulation and continuous innovation and improvement in actual production are required to truly ensure the safety and economy of new energy vehicles.
