How does powder metallurgy gear ring break through the limit of wear resistance?

Powder metallurgy technology is a process method for manufacturing parts by pressing and sintering metal powder. Compared with traditional casting, forging and machining, powder metallurgy technology has the advantages of high material utilization, low manufacturing cost, superior performance, high dimensional accuracy and the ability to manufacture complex shapes. These advantages make powder metallurgy gear ring widely used in transmission systems, engine components and auxiliary systems.
The manufacturing process of powder metallurgy gear ring includes powder preparation, pressing and forming, sintering treatment and subsequent finishing and surface treatment. In the powder preparation stage, it is necessary to select suitable metal powder and consider the influence of its particle size, shape and distribution on the performance of the final product. In the pressing and forming stage, high-precision molds and strict process parameter control are used to ensure the close bonding and uniform distribution of powder particles. Sintering treatment is a key step in the powder metallurgy process, which determines the density and performance of the final product. By accurately controlling the sintering temperature, time and atmosphere and other conditions, a gear ring with good wear resistance can be obtained.
In terms of quality control, the manufacturing process of powder metallurgy gear ring needs to strictly follow international standards such as ISO to ensure that every link from raw materials to finished products meets quality requirements. In addition, advanced testing equipment and technical means are used to strictly inspect and test the finished products to ensure that their tooth shape and dimensional accuracy meet the design requirements.
The wear resistance of powder metallurgy gear ring is affected by many factors, including material composition and structure, manufacturing process, processing and surface treatment, working environment and use conditions. The alloy elements and crystal structure in the material composition have a direct impact on the wear resistance, while the steps of pressing, sintering and heat treatment in the manufacturing process determine the density and organizational structure of the material. In addition, finishing and surface treatment can further improve the surface quality and wear resistance of the gear ring. In terms of working environment and use conditions, factors such as temperature, lubrication conditions, load and speed will also affect the wear resistance.
