Manufacturing of segments for cutting blades by powder metallurgy

Diamond cutting discs for construction materials with incorporated dry lubricant will be developed. The lubricant is expected to reduce friction and consequently improve the cutting performance and decrease the power consumption. The segments will be produced by uniaxial compaction of metal powder, diamond, and lubricant mixtures, followed by high temperature sintering. Dry lubricants with different composition, morphology, size, and volume fraction will be employed. The performance of the discs made with the segments will be assessed by cutting tests.
