Plasma cladding technology began to be applied in industrial settings in the 1960s. It utilizes the tungsten electrode of a welding torch as the negative electrode and the substrate as the positive electrode, generating plasma between them to produce heat.

The preparation of WC88%-12%Co powder, a tungsten carbide-based thermal spray powder, involves several key steps to ensure the desired properties and particle size distribution. This powder is widely used in various applications due to its excellent hardness, wear resistance, and thermal stability. Below is a detailed description of the preparation process.
