Why Powder Metal (PM) is good for the gears manufacturer?
Synchronizer gears, oil pump gears, and engine gears are examples of where the auto industry has switched from wrought steel to powder steel as a cost-effective alternative to machined gears in larger series. When designing PM gears, especially power transmission gears in PM, it becomes increasingly important to understand how to optimize the gear flanks as well as the gear body. The next step will be power transmission gears.The gear flanks on PM gears are softer than steel gear flanks, so they can’t work at their optimal potential when crowned according to a model for wrought steel gear flanks. That’s why it’s important to optimize the material in the gear body to take advantage of the power of powdered metal. In this paper you’ll learn about implications of crowning PM gears both axially and radially, as well as gear body design possibilities. You’ll also find out more about the damping properties of steels.

The Advantages of Powdered Metal?
1.Material powder metallurgy can produce refractory metals, compounds, pseudo-alloys, and porous materials.
2.Powder metallurgy doesn’t require mechanical processing to produce the final size, so it saves metal and reduces costs. This method is less wasteful than general processing methods, where up to 80% of the metal can be lost.
3.The powder metallurgy process does not melt the material during material production, so impurities brought by other substances will not mix. Sintering is carried out in a vacuum and in a chemically reducing atmosphere, preventing oxidation and contamination. Therefore, the product purity is quite high.
4.Powder metallurgy can ensure the correct composition and uniform proportioning of materials.
5.With powder metallurgy, a large number of uniform shapes can be produced, such as gears and other products, greatly reducing production costs.

Why is powder metallurgy used for gears?
Additionally, PM allows for the use of a wide range of materials, including steel, stainless steel, brass, bronze, and others, enabling gear manufacturers to create components with specific properties such as strength, wear resistance, and corrosion resistance.Another reason why PM is preferred for gears is that it can significantly reduce material waste compared to traditional machining methods. This is due to the increased ability of PM to create net or near-net-shaped parts, meaning that much less material is discarded during production.
Additionally, PM has excellent repeatability, which allows for consistent quality and performance in the final product.Overall, PM is an ideal process for making gears that require high precision, strength, and durability while also minimizing waste and enabling the use of a wide range of materials.
What is powder metallurgy process for gear manufacturing?
Powder Metallurgy (PM) is a process used for gear manufacturing that involves the following steps:
- Powder Production: Raw materials are first sourced to produce metal powders that match the desired end-product properties. These powders may be made through various processes, including atomization, mechanical alloying, or electrolysis.
- Blending: The metal powders are blended with binders and lubricants to create a mixture. The binder helps hold the powder together during the compacting stage, while the lubricant reduces friction and prevents sticking during the compacting process.
- Compacting: The blended mixture is then compacted into a pre-determined shape using high pressure in a die. This creates a “green” part with a specific shape but without the necessary strength.
- Sintering: The “green” part is placed in a furnace and heated at a high temperature, typically between 1120°C and 1250°C, causing the metal particles to fuse together. This results in a final product with the desired strength, density, and microstructure.
- Finishing: The finished product may require additional operations such as milling, drilling, or grinding to achieve the final shape, size, and surface finish.Using PM to manufacture gears offers many advantages, including the ability to produce complex shapes, high precision, and excellent material utilization. Additionally, PM gear manufacturing can be highly efficient and cost-effective.

Why is powdered steel better?
Secondly, powdered steel can be sintered at lower temperatures, resulting in less distortion and a finer grain structure than traditional steel. This makes it easier to machine and enhances mechanical properties.
Lastly, powdered steel allows for the incorporation of alloying elements, such as vanadium, molybdenum, and cobalt, which are difficult or impossible to incorporate into traditional steel. These elements can further improve the properties of the steel, making it more durable and resistant to corrosion.
What is the strength of powdered metal?
Powdered metal is a material made by compacting and sintering metal powders to form solid parts. The strength of powdered metal can vary depending on factors such as the composition of the metal powder used, the sintering conditions, and any secondary processing that is done to the part.
In general, powdered metal parts can have excellent strength properties due to the uniformity of their composition. This is because the metal powders used in the process are thoroughly mixed before being compacted, so the resulting part has a homogeneous structure with no defects or inconsistencies that could weaken it.
Additionally, the sintering process used to fuse the metal particles together can result in grain structures that are smaller and more uniform than those found in conventionally cast or forged parts. This can enhance the strength and toughness of the part, as well as its resistance to wear and fatigue.Overall, the strength of powdered metal parts can be tailored to meet the specific requirements of a given application through careful selection of the metal powder composition and processing parameters.
