The Technology Development Forum of Superhard Material was held on October 27th -28th 2009 by superhard material sub-association of CMTBA. There are 25 experts and scholars to deliver the speech on the industrial economic situation and technology research. The essays cover industrial development, superabrasives and relevant material, superhard products and application, raw material, testing equipments, management, research, etc. The essays reflect the technology level of superhard material industry.

In the afternoon of 27th, the first half of technology forum presided over by Professor Wang Qinsheng who is the vice-director of superhard material sub-association expert committee.

Speech topic:Economic development situation of superhard material industry in 2008               Speaker: Li Zhihong

Abstract:

This article analyzed economic development situation of superhard material industry influenced by economic crisis. The key economic indicator declined by large margin, but product structure improved remarkably. The economy swayed at high levels.

Speech topic:Pre-alloyed powder technology and the development of Fe based Pre-alloyed powder      

Speaker: Fang Xiaohu

Abstract:

Pre-alloyed powder is one of the most important advanced technologies of making diamond tool. This article analyzes the characteristics and application of pre-alloyed powder at home and abroad and introduces the new development of Fe based and alloy powder preparation.

Speech topic: Diamond metal composite: heated through interface of computer chips          Speaker: Fan zhizhong

Abstract:

The article talked about not only design concept of diamond metal radiation fin but provided many testing results and suggested how to avoid temperature abuse of CPU.

In the afternoon of 27th the second half of technology forum presided over by Sun Yuchao

Speech topic: Research progress of boron-based superhard material             Speaker: Kou Zili

Abstract:

The synthetic and design of superhard material is the popular topic in the material science research field. In recent years, with the development of design theory of superhard material, people can find the material that is harder than diamond through experiments and theory.

Speech topic: The improvement of PCD/PCBN used in cutting process            

Speaker: Jiang Rongchao

Abstract:

This article gave a brief introduction to the development of PCD/PCBN, described its quality and characteristics, and discussed how to improve its quality and performance.

Speech topic: SPS sintered diamond and super-composites of ceramics              Speaker: Wang Mingzhi

In the morning of 28th the technology forum presided over by Liu Mingyao.

Speech topic: Raman spectrum of different kinds of CBN crystal             Speaker: Lu Zhanling

Speech topic: Analysis of diamond film’s industrial application              Speaker: Wang Guangzu

Abstract:

This article presented few examples that showed the function and status of CVD diamond film in the modern science and technology. It is only the beginning of industrial application of CVD diamond film. There are a lot of mystery to explore, find and mater. At the same time, this article pointed out that the solutions of a few technical problems were unsatisfactory. But the application of CVD diamond film expanded widely.
