Atomized materials for powder metallurgy
Powder metallurgy (PM) is a well-known technology in metallurgy and materials science, which is used for making metal and alloy parts from powdered forms. This process entails the combination of powders of suitable size and composition, shaping by using press-forging, sintering and surface treatment. This manufacturing method can produce a wide range of materials and components, with excellent properties and close tolerances. In powder metallurgy, atomized powders are used for a variety of components, including gears, bearings and parts for automotive, aerospace and medical industries.
Atomized powder is a rapidly solidified powder that has been produced in a form of small particles by melting and atomization. Atomic forces act on the surface of the liquid droplets, causing the liquid droplets to break down into smaller particles, which then solidify into powder form. The process is carried out with the help of a gas or gas-vapor mixture. The size of the powder particles depends on the atomization conditions and the properties of the material being atomized.
Atomized powder is used in industries such as powder metallurgy, injection moulding and surface coating. In powder metallurgy, atomized powder is used for the production of ferrous and non-ferrous parts. It helps to produce components with high precision and uniformity, with good dimensional accuracy. The atomized powder is mixed with a binding agent and formed into the desired shape using press-forging, sintering and surface treatment. The resulting components have excellent properties due to their uniform structure.
Atomized powder is also used in injection moulding to create a finished product from a pre-determined design. The powder is heated, sprayed onto a mould to form a shape and then allowed to cool. In surface coating, atomized powder is used to cover the surface of an object to improve its wear resistance, corrosion resistance, hardness and heat resistance.
Atomized powders are used in a variety of industries due to their advantageous properties and cost-effectiveness. Atomized powders offer high purity and uniformity, fine particle size distribution and low porosity. They also provide improved mechanical characteristics such as wear resistance and fatigue strength. In addition, atomized powders are also cost-effective since they require less energy to produce and are lighter to transport.
Atomized powders offer a wide range of properties and capabilities, allowing various industries to create the best components and materials. As the demand for atomized powder materials increases and innovation continues to develop, atomized materials will become a reliable and cost-effective solution for many industries and manufacturers.
