The novel process, the ball impact process, in which balls are accelerated and impacted repeatedly to activate mechanochemical effect efficiently were developed and the fabrication of DLC coatings was tried. In addition, to optimize process conditions, the numerical simulation model was developed on the basis of the discrete element method. Owing to the limitation of operation load for the experimental apparatus, synthesis of DLC could not be confirmed in the experimental conditions conducted ; however, it was estimated by the simulations that the maximum contact stress given can increase up to more than tripled by increases in both the vibration amplitude and frequency.

提出了球冲击的新工艺，即通过对球的多次加速冲击来有效地激活机械力化学效应，并尝试了类金刚石涂层的制备。此外，为了优化工艺条件，在离散单元法的基础上建立了数值模拟模型。由于实验装置工作载荷的限制，在所进行的实验条件下不能确定DLC的合成；然而，通过模拟估计，所给出的最大接触应力可以随着振动幅度和频率的增加而增加两倍以上。
