Comparison of thermal stability of synthetic and milled diamonds with grain size of 400 mesh;

High power transverse flow CO2 laser was used to scan the brazing alloy and diamond grits.

In this thesis, CO_2 laser sintering experiments of bronze-Ti and bronze-Co-Ni powder with diamond grits have been done, aiming for exploring the new technique of manufacturing peculiar-shaped diamond tools and new synthetic material.

Compressive strength and the surface form and structure of the uncoated and coated diamond particles are measured and analyzed by a compressive strength meter and a metallograph, respectively.

Quality control technique of the artificial diamond particles also attracts many people s interests.

The influence of many factors, such as the size and arrangement of hot filaments, the temperature field of substrate and the distribution of small diamond abrasive particles on the growth rate and quality of homoepitaxial single crystal diamonds were analyzed.
