Plaque de carbure

Plaques en carbure are essential components in a variety of industries, including manufacturing, mining, and metalworking. Known for their exceptional hardness, wear resistance, and durability, carbide plates are the go-to solution for applications requiring strength and longevity. But what makes them so special? Let’s break down everything you need to know about carbide plates, from their composition to their applications and even how to select the right one for your needs.

Qu'est-ce qu'une plaque de carbure ?

Carbide plates, also known as tungsten carbide plates, are made from a composite material primarily consisting of tungsten carbide (WC) and a metallic binder, typically cobalt or nickel. These plates boast incredible properties, including extreme hardness and high wear resistance, making them ideal for heavy-duty applications.

Think of a carbide plate as a shield that stands up to the harshest conditions—whether it’s high heat, intense friction, or corrosive environments.

Raw Materials and Composition of Plaques de carbure

Main Ingredients

1. Carbure de tungstène (WC) : This is the star ingredient. Known for its unparalleled hardness (second only to diamond), tungsten carbide forms the base of these plates.
2. Binders: Common binders include:

• Cobalt: Offers toughness and impact resistance.
• Nickel: Adds corrosion resistance, especially for applications in chemical environments.

1. Taille des grains : The finer the grain, the harder and more wear-resistant the plate.

Déroulement du processus de production Plaques de carbure

Ever wondered how carbide plates are made? Here’s the simplified production process:

1. Préparation de la poudre :
   Tungsten carbide powder is mixed with binders (like cobalt) to create a uniform mixture.
2. Pressage :
   The mixture is pressed into the desired shape under high pressure.
3. Frittage :
   The pressed plate is heated at extremely high temperatures in a sintering furnace. This fuses the particles and increases the material’s density.
4. Finition :
   The plate is ground and polished to meet precise specifications.
5. Contrôle de la qualité :
   Every plate undergoes rigorous testing to ensure it meets hardness, toughness, and wear-resistance standards.
