TC4 鈦合金棒在(zai)(zai)生產中，由于所用材質與工(gong)藝的差別(bie)，對部分TC4、TC11鈦(tai)棒(bang)來(lai)說，我們常(chang)需進(jin)行表面外理(li)(li)。我們作(zuo)為(wei)鈦(tai)合金(jin)棒(bang)專(zhuan)業供應(ying)商，在(zai)(zai)多年的實際生產中，為(wei)大(da)家整理(li)(li)了以下物理(li)(li)拋光(guang)方法，適宜(yi)于鈦(tai)棒(bang)與鈦(tai)制(zhi)品的表面拋光(guang)。
1、細研磨
即采用常規的各類(lei)金剛砂橡皮輪對鈦(tai)及含(han)鈦(tai)合金鑄(zhu)件(jian)表(biao)面(mian)進(jin)行研磨。研磨時(shi)需注意(yi)的問題仍然是勿使鑄(zhu)件(jian)產熱，不能造成(cheng)鑄(zhu)件(jian)表(biao)面(mian)的研磨傷，并使整(zheng)個表(biao)面(mian)達(da)到平整(zheng)光滑。
2、桶研磨(mo)法
所謂桶(tong)(tong)研(yan)(yan)(yan)(yan)磨(mo)法是將被(bei)加工(gong)鑄(zhu)件(jian)(jian)(jian)、研(yan)(yan)(yan)(yan)磨(mo)料、水及添加劑放入桶(tong)(tong)式研(yan)(yan)(yan)(yan)磨(mo)槽內(nei)，研(yan)(yan)(yan)(yan)磨(mo)桶(tong)(tong)產(chan)生(sheng)旋(xuan)轉和振動，使研(yan)(yan)(yan)(yan)磨(mo)料的(de)(de)(de)(de)混合物和被(bei)加工(gong)鑄(zhu)件(jian)(jian)(jian)之(zhi)間產(chan)生(sheng)摩擦，將鑄(zhu)件(jian)(jian)(jian)表面研(yan)(yan)(yan)(yan)磨(mo)光滑(hua)，平整。其特點(dian)是不(bu)產(chan)生(sheng)粉塵污染，勞(lao)動強度(du)低，不(bu)會發(fa)生(sheng)常規研(yan)(yan)(yan)(yan)磨(mo)過(guo)程中的(de)(de)(de)(de)產(chan)熱現(xian)象。目前(qian)，日本已有(you)商(shang)品(pin)化的(de)(de)(de)(de)桶(tong)(tong)研(yan)(yan)(yan)(yan)磨(mo)機及用于對鈦及含鈦合金鑄(zhu)件(jian)(jian)(jian)、其它金屬鑄(zhu)件(jian)(jian)(jian)及塑料等(deng)研(yan)(yan)(yan)(yan)磨(mo)用的(de)(de)(de)(de)研(yan)(yan)(yan)(yan)磨(mo)料出售(shou)，經(jing)過(guo)試驗證(zheng)實，pk系列(lie)磨(mo)料的(de)(de)(de)(de)研(yan)(yan)(yan)(yan)磨(mo)效率(lv)為(wei)最(zui)高(gao)，但表面的(de)(de)(de)(de)粗糙率(lv)也是最(zui)高(gao)。SA和B系列(lie)研(yan)(yan)(yan)(yan)磨(mo)料的(de)(de)(de)(de)研(yan)(yan)(yan)(yan)磨(mo)效率(lv)雖(sui)不(bu)如PK，但被(bei)研(yan)(yan)(yan)(yan)磨(mo)后的(de)(de)(de)(de)鈦鑄(zhu)件(jian)(jian)(jian)表面平滑(hua)度(du)為(wei)最(zui)高(gao)。目前(qian)，第四軍醫大學(xue)已研(yan)(yan)(yan)(yan)制成功了國(guo)內(nei)第一臺牙科(ke)用桶(tong)(tong)式研(yan)(yan)(yan)(yan)磨(mo)機。
3、機械(xie)拋光(guang)法
使用(yong)不(bu)同規格的(de)軟(ruan)布(bu)輪或黑(hei)毛刷，蘸以鈦(tai)及含(han)鈦(tai)合金(jin)(jin)專用(yong)拋(pao)(pao)(pao)光(guang)(guang)(guang)(guang)(guang)(guang)膏(gao)對鈦(tai)及鈦(tai)合金(jin)(jin)表面(mian)拋(pao)(pao)(pao)光(guang)(guang)(guang)(guang)(guang)(guang)的(de)方(fang)(fang)法。在對鈦(tai)鑄件(jian)進(jin)行拋(pao)(pao)(pao)光(guang)(guang)(guang)(guang)(guang)(guang)時，必(bi)須做(zuo)到完(wan)(wan)全(quan)清楚鑄件(jian)表面(mian)污染層及未發生新的(de)研磨硬化(hua)層，否則將無法達到理(li)想(xiang)的(de)拋(pao)(pao)(pao)光(guang)(guang)(guang)(guang)(guang)(guang)效果(guo)。拋(pao)(pao)(pao)光(guang)(guang)(guang)(guang)(guang)(guang)時仍采用(yong)高轉速、輕(qing)壓(ya)力的(de)方(fang)(fang)式(shi)。有人(ren)曾試(shi)驗(yan)過使用(yong)綠(lv)拋(pao)(pao)(pao)光(guang)(guang)(guang)(guang)(guang)(guang)膏(gao)對鈦(tai)及含(han)鈦(tai)合金(jin)(jin)鑄件(jian)進(jin)行拋(pao)(pao)(pao)光(guang)(guang)(guang)(guang)(guang)(guang)，取得了較(jiao)為理(li)想(xiang)的(de)拋(pao)(pao)(pao)光(guang)(guang)(guang)(guang)(guang)(guang)效果(guo)。經拋(pao)(pao)(pao)光(guang)(guang)(guang)(guang)(guang)(guang)后的(de)鈦(tai)及含(han)鈦(tai)合金(jin)(jin)鑄件(jian)不(bu)能立即進(jin)入水洗，一(yi)定要是表面(mian)氧化(hua)膜完(wan)(wan)全(quan)成(cheng)形(xing)后方(fang)(fang)可進(jin)行水洗，否則其表面(mian)會產生變暗的(de)現象(xiang)。
