人体血液与不同成分及表面粗糙度钛合金的润湿性

Wettability of Human Blood on Titanium Alloy Surface with Different Compositions and Roughnesses

摘要: 采用JY-82接触角测定仪测试了不同红细胞压积(HCT)的人体血液与TA2、TC4、TLM三种钛合金在不同表面粗糙度下的接触角θ,研究了人体血液对钛合金表面的润湿性.结果表明:试验条件下,合金的表面越粗糙,血液与其的润湿性越好;随血液HCT的增大,其与合金的润湿性变差,血液与TLM钛合金的润湿性最好,与TC4合金的次之,与TA2合金的最差.

Abstract: The contact angle (θ)of different HCT bloods on three titanium alloys (TA2,TC4,TLM)surfaces which had different roughnesses was studied using JY-82 contact angle meter.The wettability of the human blood on the titanium alloy surface was investigated.The results show that the rougher the alloy surface,the better the wettability of the blood on the surface under the test conditions.The bigger the blood′s HCT,the worse the wettability on the alloy surface.The wettability of the blood on the TLM alloy was the best,the TA2 titanium alloy was the worst,and the TC4 alloy was moderate.
