2納米顆粒或硅酸鈉制備了TC4鈦合金微弧氧化膜。使用XRD、SEM、EDS、電化學工作站和摩擦磨損儀檢測并分析了添加劑對膜層的影響。結(jié)果表明，SiO2納米顆粒和硅酸鈉的添加能夠顯著改善膜層的性能，膜層主要物相為金紅石型和銳鈦礦型TiO2、α-Al2O3、γ-Al2O3、Al2TiO5與SiO2。成膜過程中，SiO2納米顆粒和硅酸鈉的加入能有效增加膜層的厚度與致密度，同時具有優(yōu)異物理性能的SiO2納米顆?？梢灾苯映练e在放電通道處，大大提高了膜層的耐磨性和耐腐蝕性。其中，添加SiO2納米顆粒的膜層具有最優(yōu)異的耐蝕性與耐磨性，腐蝕速率與平均摩擦系數(shù)最低分別為4.095×10-5 mm/a和0.30。;TC4 micro-arc oxidation (MAO) coatings were prepared by adding SiO2 nanoparticles or sodium silicate to the sodium meta-aluminate-based electrolyte. The effect of additives was investigated by XRD, SEM, EDS, electrochemical and wear tests. The results show that additives can considerably accelerate the formation of MAO coatings. The coatings are mostly composed of rutile and anatase TiO2, α-Al2O3, γ-Al2O3, Al2TiO5 and SiO2. Sodium silicate and SiO2 nanoparticles added to the coating can effectively reduce the size of micropores and increase its thickness, whereas SiO2 nanoparticles with superior physical properties can be directly deposited at the discharge channel, significantly increasing the coating's resistance to wear and corrosion. The coating with SiO2 nanoparticles exhibits the best overall performance, with the lowest corrosion rate and average friction coefficient of 4.095×10-5 mm/a and 0.30, respectively."/>
