ABSTRACT:
Disclosed are a process for laminating a functionally gradient material and a laminating apparatus for the same. The process therefor includes a suspending step and a functionally gradient material laminating step. In the functionally gradient material laminating step, solid-liquid separation is carried out to a suspension while varying the mixing rates of the suspension particles contained therein continuously or in a multi-staged stepwise manner. Therefore, the functionally gradient material layer thus laminated offers a composition gradient varying continuously or in a multi-staged stepwise manner in the thicknesswise direction thereof in a superior continuity, and the composition fluctuates less in the planewise direction thereof. In addition, the process and the laminating apparatus have obviated the atomizing and the spraying which adversely affect a working environment.
