超硬プレート

超硬プレート 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.

超硬プレートとは？

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.

Types of Carbide Plates

Here’s a detailed table showcasing the different types of carbide plates based on their composition, intended application, and unique properties.

Raw Materials and Composition of 超硬プレート

Main Ingredients

1. 炭化タングステン（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. 粒の大きさ： The finer the grain, the harder and more wear-resistant the plate.

製造工程の流れ 超硬プレート

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

1. パウダーの調製：
   Tungsten carbide powder is mixed with binders (like cobalt) to create a uniform mixture.
2. プレスする：
   The mixture is pressed into the desired shape under high pressure.
3. 焼結：
   The pressed plate is heated at extremely high temperatures in a sintering furnace. This fuses the particles and increases the material’s density.
4. 仕上げ：
   The plate is ground and polished to meet precise specifications.
5. 品質管理：
   Every plate undergoes rigorous testing to ensure it meets hardness, toughness, and wear-resistance standards.
