Tungsten carbide products are typically manufactured using a powder metallurgy process, which involves the following steps:
1. Powder preparation: Tungsten carbide powder and metallic binder powder (typically cobalt or nickel) are mixed together to form a homogeneous mixture.
2. Compacting: The mixed powders are then compacted under high pressure to form a green compact with the desired shape and dimensions.
3. Sintering: The green compact is then heated in a furnace under controlled conditions of temperature and atmosphere. During this process, the metallic binder melts and diffuses into the tungsten carbide particles, forming a dense, solid material with high strength and hardness.
4. Finishing: The sintered part may then undergo additional finishing operations such as grinding, machining, polishing or coating to achieve the desired surface finish and dimensions.
The exact manufacturing process may vary depending on the specific product and application, but these are the general steps involved in producing tungsten carbide products.
