The experimental study on CO2 laser sintering of diamond fine powder compact

In order to improve diamond fine powder sinter's mechanical property,using the present laser technique,high power transverse CO2 laser is used to sinter diamond fine powder compact to study the integrating capability in the sinter between diamond fine powder and metallic powder,microstructure and the forming mechanism of microstructure in the different laser technical parameters.The results show that the fine sintering will be gained in the reasonable laser technical parameter,which can improve densenses and wear resistance,inaugurate a new technique of manufacture diamond tools.
