    2021-3-3 · Sun Jian analyzed the factors that affect the surface quality of silicon nitride ceramics. It has found that between friction depth and speed, the latter factor has a greater impact on friction force and the quality of surface [21, 22]. The frictional wear performance of ceramics is influenced by the nature of materials, the environmental conditions, the pairing friction materials and more.

    Silicon nitride components may be produced in dense form from a powder through the conventional sintering or hot-pressing routes. An interesting and important feature of the material, however, is that lower density (2300–2700 kgm –3) components may be produced directly by the nitridation of compacted silicon powder—the reaction-bonding (or reaction-sintering) route.
