采用微弧氧化方法對(duì)醫(yī)用鈦合金表面進(jìn)行改性,利用X射線衍射分析(XRD)、掃描電鏡(SEM)對(duì)微弧氧化膜層的表面形貌和化學(xué)成分進(jìn)行分析,通過(guò)小振幅往復(fù)摩擦磨損試驗(yàn)測(cè)量膜層的耐磨損性能。
醫(yī)用鈦合金的微弧氧化膜層組織及其磨損性能Microstructure and its wear property of micro-arc oxidation?coating on biomedical titanium alloy采用微弧氧化方法對(duì)醫(yī)用鈦合金表面進(jìn)行改性,利用X射線衍射分析(XRD)、掃描電鏡(SEM)對(duì)微弧氧化膜層的表面形貌和化學(xué)成分進(jìn)行分析,通過(guò)小振幅往復(fù)摩擦磨損試驗(yàn)測(cè)量膜層的耐磨損性能。結(jié)果表明:鈦合金經(jīng)過(guò)微弧氧化表面處理后,所得膜層存在不同尺寸的放電微孔,氧化膜內(nèi)層相對(duì)外層較為致密;膜層主要由大量金紅石型TiO2相、非晶相SiO2及少量銳鈦礦型TiO2相組成;與基體相比,微弧氧化膜層的初期摩擦因數(shù)從0.7降低至0.1,耐磨性提高。
The coating prepared by micro-arc oxidation (MAO) on biomedical titanium alloy was investigated. The surface morphology and chemical composition of MAO coating were analyzed by X-ray diffractometry and scanning electron microscopy (SEM). The anti-wear property of the coating was measured through small amplitude oscillatory reciprocating friction and wear test. The results show that the MAO coating has some micropores with different dimensions and the inner layer of the coating is denser compared with the outer layer. The composition of the coating comprises majority of rutile TiO2?and amorphous phase SiO2. A fraction of the composition is anatase TiO2. The preliminary friction coefficient of the coating decreases from 0.7 to 0.1. The micro-arc oxidation treatment improves the anti-wear property of the titanium alloy.
