Introduction
Powder metallurgy (PM) is a relatively new material forming technique that can be used to produce friction products. PM is the process of blending fine powdered materials, compressing them into a desired shape, and then heating the compressed material in a controlled atmosphere to bond the material. Compared to traditional friction products, the use of PM offers a number of advantages, including higher yield rates, better functionality, and increased durability.
Overview of PM friction products
PM friction products are made by first blending together various powdered materials and additives, such as steel, graphite, and molybdenum disulfide. These materials are then compressed into a desired shape or form and precisely machined by a variety of processes, including machining with an EDM Lathe. This process creates components of precise sizes, shapes, and tolerances that are then heat treated to increase strength and hardness.
The heat treatment process involves subjecting the component to temperatures of up to 2000°F (1093°C). The heat treatment process is typically done in a vacuum furnace to prevent oxidation and other chemical reactions from occurring that could affect the properties of the component.
Advantages of using PM friction products
1-Yield Rates: PM friction products offer higher yield rates than traditional friction products. This is because the compaction of the component is much more precise than with traditional methods, allowing more precise parts to be produced with less downtime and reduced costs.
2-Functionality: PM friction products also offer increases in functionality and performance. This is because the components are specifically designed and machined to match the exact specifications and requirements of the application. This allows for an increase in efficiency and overall life of the product.
3-Durability: PM friction products also offer increases in durability. Because the components are heat treated in a vacuum, surface contaminants are reduced and the components have a better bond. This leads to improved durability and a longer life.
Conclusion
Overall, PM friction products provide a number of advantages over traditional friction products, including higher yield rates, better functionality, and increased durability. PM friction products are a great choice for applications that demand precision, performance, and long-lifetime components.
