【摘要】：采用在Ringer模擬體液靜態(tài)體外浸泡的方法,研究工業(yè)純鈦試片經(jīng)過一定時間的浸泡后的失重和表面形貌的變化。采用等通道徑角擠壓(ECAP)方法處理工業(yè)純鈦并與粗晶純鈦進行對比,對ECAP處理的TA9和粗晶TA9也做了對比。結(jié)果表明:純鈦在400℃ECAP處理后的微觀組織形成具有明顯方向性的板條狀組織,ECAP純鈦表面沉積的Na Cl晶體數(shù)量大于粗晶Ti,TA9也表現(xiàn)出相似結(jié)果。純鈦的腐蝕機制是一種受到電偶腐蝕控制的均勻腐蝕,細(xì)晶組織導(dǎo)致電偶的數(shù)量增加。
[Abstract]:The weight loss and surface morphology of the commercial pure titanium specimen after immersion for a certain time were studied by the method of static immersion in Ringer simulated body fluid in vitro. The industrial pure titanium was treated by equal channel angular extrusion (ECAP) and compared with coarse pure titanium. The TA9 and TA9 treated by ECAP were also compared. The results show that the microstructures of pure titanium treated at 400 鈩，
