New Technology for Tungsten Carbide Nozzle Reducing abrasion III

Recently, so many successes of high performance ceramics research provide new thinking for new nozzle developing. The new high-performance ceramic mostly apply submicron and nano powders, whiskers, fibers, chips, so that the grains and grain boundaries in combination between them have reached the nanometer level, and can be sintered at a lower temperature to achieve high density and high strength. In terms of sintering temperature, the products has lower 400 ° C sintering temperature than coarse-grained material and can withstand bending deformation without cracks at 180℃ sintering temperature.

In addition, some easy solution, immiscible components on the nanoscale composite can form a new composite material, which can improve the performance of hardness, toughness and wear resistance and other properties to a certain extent. When these techniques are widely in grinding compound nozzle, it will make a progress in jet flow nozzle and get a new breakthrough.
