Overview of Spherical Tungsten Carbide-Cobalt Powder

Spherical tungsten carbide-cobalt powder is a composite material made up of karbid wolframu (WC) and a binder, typically kobalt (Co). The material is created through rozprašování processes, which result in sférické částice. This spherical shape is particularly important because it enhances the powder’s průtočnost, takže je ideální pro aditivní výroba, tepelné stříkání, a prášková metalurgie.

Tungsten carbide is known for its tvrdost, while cobalt adds tvárnost a houževnatost, making the composite highly resistant to wear, corrosion, and high temperatures. This combination of properties makes spherical WC-Co powder a go-to material for cutting tools, wear-resistant coatings, and other high-stress applications.

Key Benefits of Spherical Tungsten Carbide-Cobalt Powder:

• Extrémní tvrdost: Tungsten carbide is among the hardest materials known, ranking close to diamonds on the Mohs scale.
• Odolnost proti opotřebení: The material’s hardness translates to excellent wear resistance, increasing the longevity of components.
• Tepelná stabilita: WC-Co can withstand high temperatures without losing its mechanical properties, making it ideal for extreme environments.
• Tekutost: The spherical shape of the powder enhances its flow characteristics, crucial for 3D printing and other powder-based processes.
• Nárazová houževnatost: Cobalt adds toughness to the composite, preventing it from becoming brittle under impact or stress.

Types, Composition, and Properties of Spherical Tungsten Carbide-Cobalt Powder

Existuje několik typů spherical tungsten carbide-cobalt powders, each tailored for specific applications. The ratio of tungsten carbide to cobalt can vary, and this ratio directly influences the properties of the powder, such as hardness, toughness, and wear resistance. The most common compositions are WC-6Co, WC-12Co, a WC-17Co, where the percentage indicates the amount of cobalt in the mix.

Zde je přehled nejčastějších typů spherical tungsten carbide-cobalt powders a jejich klíčové vlastnosti:

Proč záleží na složení:

Bilance karbid wolframu a kobalt significantly impacts the material’s performance. A higher cobalt content (such as in WC-17Co) increases the toughness but slightly reduces the hardness, making it more suitable for impact-prone environments like mining or oil drilling. On the other hand, a lower cobalt content (like WC-6Co) results in higher hardness, ideal for cutting tools where wear resistance is paramount.
