Metal forgings play a key role in the support and transmission of various mechanical equipment, and its performance and quality have an important impact on the operation of the entire equipment. In recent years, with the continuous development of science and technology, many new materials and processing technologies have been applied to the production of metal forgings, greatly improving their performance and quality. This paper will introduce some new materials and processing technologies applied in metal forgings, and analyze their improvement of metal forgings performance.
The application of new materials
Powder metallurgy
Powder metallurgy is a common technique for manufacturing metal parts by sintering and forming metal powders to obtain parts with the desired shape and properties. Powder metallurgy is widely used in the manufacture of metal forgings, especially in the manufacture of high-strength, high-wear parts with significant advantages. Through powder metallurgy technology, metal forgings with complex structure and high precision can be produced to meet the requirements of various complex working conditions.
Fusion welding
Fusion welding is a method of joining two or more metal joints by heating them to a molten state and then cooling them to solidify. Fusion welding is often used in the manufacturing of metal forgings to connect metal materials of different materials and thicknesses to achieve high quality and efficient production. Through melting welding technology, metal forgings of different materials can be reliably connected to achieve excellent mechanical properties and stability.
Laser processing
Laser processing is a technology that uses high energy laser beam to cut, weld, punch and other processing materials. Laser machining has the advantages of high efficiency, high precision and low damage in the manufacture of metal forgings. Through laser processing technology, high precision drilling, cutting and welding can be achieved on the metal forgings to meet the design requirements of various complex shapes and structures.
Second, the improvement of performance of new materials
Increase strength
The application of new materials has significantly improved the strength of metal forgings. For example, metal forgings produced by powder metallurgy technology have higher strength and hardness due to the high purity and complete crystallization of the metal powder. At the same time, parts manufactured by powder metallurgy also have better isotropy and can better withstand complex stresses.
Increase plasticity and toughness
The addition of new materials also improves the plasticity and toughness of metal forgings. For example, the application of high-strength aluminum alloy and titanium alloy makes the metal forgings maintain high strength at the same time, but also has good plasticity and toughness, and can better adapt to the dynamic load and impact load working environment.
Improved wear resistance
Wear resistance is one of the important properties of metal forgings, which directly affects the service life of equipment. The emergence of new materials has greatly improved the wear resistance of metal forgings. For example, metal forgings made of high carbon steel, alloy steel and other materials have higher wear resistance and corrosion resistance, and can maintain stable performance in harsh working environments.
Enhanced fatigue resistance
Fatigue failure is one of the common failure forms of metal forgings, which has a serious impact on the normal operation of equipment. The application of new materials helps to enhance the fatigue resistance of metal forgings. For example, by optimizing the composition and organizational structure of the material, it can make the metal forgings have better fatigue resistance and extend the service life of the equipment.
Third, market prospects
With the continuous development of science and technology, the application of new materials and processing technology in the manufacturing of metal forgings will be more extensive. In the future, hardware forgings with high performance, high precision and high efficiency will be more and more favored by the market. In terms of new materials, the development of powder metallurgy, melting welding, laser processing and other technologies will continue to promote the performance of metal forgings; In the market, the continuous development of the machinery manufacturing industry and the continuous improvement of equipment performance will bring a broader development space for hardware forgings.
In short, the emergence of new materials and the progress of processing technology have brought unprecedented development opportunities for hardware forgings. Only by constantly exploring, innovating and applying new technologies and materials can we continuously improve the performance and quality of hardware forgings and meet the increasing market demand.
