AI Technical Summary
Traditional high-temperature and high-pressure methods for preparing superhard composite materials suffer from limitations such as mold constraints, difficulty in realizing complex structures, high residual stress, and low production efficiency, making it difficult to meet the rapid production needs of customized products.
A high-performance superhard composite material is prepared by using an extrusion additive manufacturing method, which involves mixing a binder phase, superhard raw material powder and organic polymer to prepare feed particles, followed by extrusion, debinding and sintering and high-temperature and high-pressure full densification.
It enables the forming of complex shapes of ultra-hard composite materials at lower temperatures, reducing residual stress, improving production efficiency, and making it suitable for the development of small-batch new products.
