等(deng)離子(zi)(zi)(zi)體(ti)表(biao)面(mian)處理是指通過(guo)等(deng)離子(zi)(zi)(zi)體(ti)中(zhong)的高能(neng)粒子(zi)(zi)(zi)對材料(liao)表(biao)面(mian)進(jin)行轟(hong)擊，使(shi)表(biao)面(mian)物(wu)質(zhi)(zhi)降解，增加(jia)表(biao)面(mian)粗糙度，若等(deng)離子(zi)(zi)(zi)體(ti)中(zhong)有其他活性(xing)粒子(zi)(zi)(zi)，如氧等(deng)離子(zi)(zi)(zi)，則可與表(biao)面(mian)物(wu)質(zhi)(zhi)發生反應而使(shi)表(biao)面(mian)活化的一(yi)種方法.
