摘要

Polycrystalline grits (polygrits) have been used widely in industry as abrasives. Due to their higher impact strength and the friable nature, polygrits are more endurable and more efficient than monocrystal grits (monogrits) in material removal applications. For example, polygrits of alumina may last longer and cut faster than monogrits. Similarly, polygrits of cubic boron nitride is a superior superabrasive than monogrits of the same.Although diamond superabrasives have been indispensable for constructional sawing applications and industrial grinding applications, there has no polygrits of diamond that are commercially available. In this research, we used a novel technology to sinter micron diamond fines to form polygrits of diamond. The characterization demonstrated that polygrits of diamond can be tough to withstand impact. But due to the presence of micro grains, the grit can sharpen itself without dulling by shedding the worn grains. This paper revealed many examples of using diamond polygrits.
