氧化鋁陶瓷燒結(jié)冷卻之后,并不代表著產(chǎn)品加工的結(jié)束,有些產(chǎn)品還達(dá)不到應(yīng)用要求,所以,還需要對其進(jìn)行加工處理,如修正尺寸、拋光等。
用比氧化鋁還要硬的金剛石、碳化硅等由粗到細(xì)逐級進(jìn)行研磨;采用Al2O3 微粉或金剛石磨膏進(jìn)行研磨拋光;采用激光加工以及超聲波加工研磨及拋光;需要用施釉的方法(適合對表面光滑度要求很高的產(chǎn)品);
用離子注入法對材料表面進(jìn)行加工,離子注入陶瓷是對現(xiàn)有增韌機理的補充, 是對制備好的陶瓷產(chǎn)品的深加工。例如:用鎳離子對陶瓷產(chǎn)品進(jìn)行鎳粒子注入處理后,機械強度、韌性會大大增強。
對氧化鋁陶瓷的拋光處理方法都是為了增加氧化鋁陶瓷產(chǎn)品表面的致密性,使陶瓷表面更加致密光滑,這不僅僅是為了美觀,更大大提高了氧化鋁陶瓷使用性能。(圖/文tujian.net.cn)
