| Research Abstract |
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.
