Problems solved by technology

However, there are difficulties in the preparation technology of a single nanocrystalline material, which often cannot meet the needs of practical applications. Many studies have combined nanoparticles and other materials into nanocomposites. Advantages, with special properties
A gear is a mechanical element with teeth on the rim that can continuously mesh to transmit motion and power. It is a mechanical part with teeth that can mesh with each other. It needs good wear resistance and toughness, but the cast steel material commonly used for gears has low hardness. Poor wear resistance, serious wear and tear, not conducive to popularization and use
