Fig.1 Consumption of diamond 2 Diamond cutting tool materials and preparation technology 2.1 Diamond cutting tool materials According to the preparation methods of diamond, diamond cutting tool materials can be divided into natural diamond, synthetic single crystal diamond, and synthetic polycrystalline diamond (PCD) and chemical vapor deposition (CVD) diamond.
With the continuous development of science and technology, preparation techniques of diamond material have become increasingly sophisticated.
Synthetic diamond of large single crystal and nanometer diamond films are two new materials.
Nanometer diamond simultaneously has properties of nanometer materials and diamond materials, and as a tool coating material, it can improve efficiency and extend tool life.

The study on TiAl alloy powders with different density by low temperature diffusion synthesis Jun Wang, Huiping Shao *, Zhimeng Guo School of materials science and engineering, University of Science and Technology Beijing, Beijing 100083, China Corresponding author, E-mail: shaohp@ustb.edu.cn Keywords: TiAl alloy powders; intermetallic compounds; diffusion reaction; low temperature; high vacuum Abstract.
This process of forming alloy materials has the advantage that the raw materials are elemental powders or alloy powders, therefore it is easy to fabricate near-net-shaped TiAl alloy products through shaped and sintered.
For example, low density powders for porous materials and high density powders for compacting materials [12].
(3) It can provide an economical method to prepare the starting materials for porous materials.
