通过原位合成反应，在氨气中用等离子辅助球磨(NH3-P球磨)制备了纳米金属氮化物和氢化物粉末。气固反应是在氨气恒压下短时间等离子体球磨镁和钛引发的，10 h后，两种体系的产物分别为纳米晶的Mg_3N_2和TiN、TiH_2。在钛粉的NH3-P球磨过程中，球磨初期生成TiH_2和TiN，然后TiH_2在进一步球磨时与N自由基反应分解，转变为TiN相。反之，C球磨10 h后，NH_3与Mg/Ti之间没有发生化学反应。放电等离子体活化分解氨气，活化了粉末表面，与高能球磨的机械效应共同促进了气固反应。
Nanocrystalline metal nitride and hydride powders were prepared using plasma-assisted ball milling in ammonia gas (NH3-P-milling) via an in situ synthesis reaction. The gas–solid reactions were triggered by a short duration of plasma milling of Mg and Ti under a constant pressure of ammonia gas, and the products in the two systems were nanocrystalline Mg3N2and TiN, TiH2after 10 h, respectively. During the NH3-P-milling of Ti powder, TiH2and TiN were formed during the initial stages of milling, and then, the TiH2decomposed during further milling upon reaction with N radicals, transforming into the TiN phase. In contrast, no chemical reaction occurred between NH3and Mg/Ti after 10 h of C-milling. The discharge plasma activated and decomposed the ammonia gas and activated the surface of the powders, which, together with the mechanical effect of high-energy ball milling, accelerated the gas–solid reactions.
