The chromium oxynitride (Cr(N,O)) obtained by substitutional solid solution of oxygen into the chromium nitride (CrN) in which it is used as a tool coating mainly, the hardness is significantly improved regardless of covalent bonding also decrease has been found. In this study, we studied for manufacturing chromium magnesium oxynitride ((Cr, Mg) (N, O))ceramics as the creation of a new hard ceramic tool materials using the above properties.The results of this study, (Cr,Mg)(N,O) powders have been successfully synthesized through the mechanical alloying under nitrogen atmosphere. In addition, We have also succeeded the preparation (Cr,Mg)(N,O) ceramics of substantially single phase. Furthermore, We have shown that (Cr,Mg)(N,O) ceramics has a high hardness above HV2000.

通过将氧置换固溶到氮化铬(CrN)中而得到的氮氧化铬(Cr(N,O))，主要用作工具涂层，发现无论共价键合如何降低，硬度都显着提高。 。 在这项研究中，我们研究了利用上述特性来制造铬镁氮氧化物（（Cr，Mg）（N，O））陶瓷作为新型硬质陶瓷刀具材料。这项研究的结果，（Cr，Mg）在氮气气氛下通过机械合金化成功合成了(N,O)粉末。 此外，我们还成功制备了基本单相的(Cr，Mg)(N，O)陶瓷。此外，我们还表明(Cr,Mg)(N,O)陶瓷具有HV2000以上的高硬度。
