In the first quarter of 2026, tungsten carbide cutting blades manufactured using Spark Plasma Sintering (SPS) technology successfully completed high-temperature testing at the Aviation Materials Research Institute.
The blades exhibit an ultra-low grain boundary oxygen content of less than 150 ppm, maintaining a hardness of 90.2 HRA at 950°C—significantly higher than the 83 HRA achieved by conventionally vacuum-sintered counterparts.
During dry cutting of ceramic matrix composites (CMC), the cutting edges showed no signs of oxidation or spalling, extending tool life by 2.8 times compared to standard tools.
