This process can be divided into several basic steps: powder preparation, pressing and forming, sintering, and post-processing. Compared with traditional casting or machining methods, powder metallurgy has the following advantages: 1.
Material savings: Since there is almost no cutting loss in the powder metallurgy process, material waste can be greatly reduced.
2. High surface smoothness: The manufactured gears have a relatively smooth surface, generally reducing the need for subsequent processing.
3. Excellent performance: By adjusting the composition of the powder materials and the manufacturing process, better physical and mechanical properties can be achieved.
4. Suitable for complex shapes: It can produce parts with complex structures, suitable for high-precision gears. Manufacturing process flow of powder metallurgy gears 1. Raw material selection and powder preparation First, selecting the appropriate metal base material is key to manufacturing powder metallurgy gears. Commonly used metal powders mainly include iron-based powders (such as iron and alloy steel) and copper-based powders.
