Obtained using diamond special physical and chemical effects

From the research point of view, to study the process and the use of diamond diamond products  Diamond blade  special physical and chemical effects in the majority, and is focused on the saw blades, drill bits and diamond thick film, thin film production technology direction, followed by diamond production technology and equipment  grinding wheel , the production of raw and auxiliary materials of diamond and diamond sorting of research purification process research, which shows more concentrated field of study, is conducive to a breakthrough success in a  cutting tools  area. From the point of view of patent applications before 1995, the number of enterprises to apply for patents has increased, peaked in 1995 and then declined slightly, but the annual volume of applications is relatively stable from one side reflects the country's diamond industry matures.
