Poly crystalline diamond sintered with Ti coated diamond particles and the manufacturing method thereof

摘要

The present invention relates to a multi-crystal diamond sintered body using titanium coated diamond powder and to a method for manufacturing same. Specifically, the multi-crystal diamond sintered body according to the present invention includes: a carbide layer; and a multi-crystal diamond layer provided on the carbide layer and formed by sintering diamond powder coated with a conductive metal. According to the present invention, processability is improved while maintaining the quality of an existing product, and thus production efficiency of the product itself can be increased and the yield and the reliability of the product can be improved.
