Superhard materials and their products mainly include diamond, cubic boron nitride, PCD, PCBN, superhard abrasive tools with high hardness, high wear resistance characteristics of a large class of materials, widely used in machining cutting, grinding, polishing processes. By using X-ray diffractometer, the types of abrasives in abrasives can be judged, the binders and various additives in abrasives can be qualitatively and quantitatively analyzed, and the lattice parameters and crystal sizes can also be obtained.
The above is the XRD pattern of a superhard abrasive. Through analysis, it can be determined that the abrasive is diamond, the binder is several different phases of copper-tin alloy, and there is a small amount of corundum abrasive as auxiliary abrasive. In addition, combined with other analytical means, the accurate content of various phases can be further determined, and then the necessary technical support is provided in the determination of the abrasive formula and subsequent formula adjustment, which helps to improve product quality and the efficiency of new product development.
