最近,美国Harvard大学与通用电气公司超硬材料部的研究人员联合开发出一种氮化碳陶瓷新材料,称之为C_3N_4材料.这种陶瓷新材料是采用合成法合成出来的硬度极高的材料(其硬度等于或超过金刚石材料的硬度).目前正在进行各方面的实验,证实其稳定性.据称,如果这种材料的硬度在实践中保持稳定的话,它将成为一种人造金刚石材料的替代物,可广泛用作磨削工具材料和切削工具的涂层材料.从目前的研究进展而言,这种材料的研究还在实验阶段,有关具体的性能尚待进一步研究和实验.这种新型材料的结构与氮化硅(Si_3N_4)材料相似,用碳原子替代了硅原子,但又与TiCN材料毫不相关.从事这项材料研究的科技人员深信,只要继续努力,这种材料必将合成为机加工用的一种新型工具涂层材料.
Recently, the United States Harvard University and General Electric Company superhard materials department researchers jointly developed a new carbon nitride ceramic material, called C_3N_4 material.This new ceramic material is synthesized using the synthesis of very high hardness Material whose hardness equals or exceeds the hardness of the diamond material, various experiments are under way to confirm its stability, and it is said that if the hardness of the material is stable in practice it will become a synthetic diamond material Can be widely used as a coating material for grinding tool materials and cutting tools, and from the current research progress, the research on this material is still in the experimental phase and further research and experiments are required for the specific properties. The new material has a structure similar to that of silicon nitride (Si_3N_4), replacing carbon atoms with silicon atoms, but not with TiCN materials.Scientists engaged in the research of this material are convinced that as long as they continue their efforts, this material A new tool coating material for machining will be synthesized.
