Thermal spray materials, especially various nickel-based, ceramic and tungsten carbide powder coating materials, have great difficulties for mechanical processing due to their high hardness, good thermal stability, uneven organization and uneven surface. At present, the processing methods adopted in China are: Grinding with diamond grinding wheel, but the processing efficiency is low and the cost is high. Grinding with corundum grinding wheel, the processing efficiency is too low, the grinding wheel loss is large, and in many cases, the processing requirements cannot be met.
