    摘要:

    采用尿素溶液對(duì)一種低模量近b型鈦合金（Ti-25Nb-3Zr-2Sn-3Mo, 或 TLM合金）進(jìn)行不同溫度的水熱處理。采用SEM、XRD、XPS、壓入法和接觸角測(cè)試分析了TLM合金處理后的表面結(jié)構(gòu)、化學(xué)成分、附著性和親水性。在105和120 ℃水熱處理后，合金表面形成了鈦酸銨的納米片薄膜；而150 ℃水熱處理后形成了納米顆粒薄膜，由銳鈦礦TiO2和Nb2O5組成。隨后的400 ℃退火熱處理使銨鹽分解和二氧化鈦結(jié)晶。生成的氧化物薄膜具有良好的附著性。復(fù)合處理增強(qiáng)了TLM合金的親水性，這有利于改善其生物相容性。

    Abstract:

    A low modulus near b type titanium alloy (Ti-25Nb-3Zr-2Sn-3Mo, or TLM alloy) was subjected to hydrothermal treatments with a urea solution at different temperatures followed by heat treatment. The surface structure, the chemical composition, adhesion and hydrophilicity of the treated TLM alloy were investigated by SEM, XRD, XPS, Rockwell-C indentation test and contact angle measurement. The results show that nanosheet films of ammonium titanate can be formed at 105 and 120 °C, while the nanoparticle film of anatase TiO2 containing Nb2O5 is formed at 150 °C on the alloy surface. The subsequent annealing heat treatment at 400 °C can decompose the ammonium salts and crystallize titania. The obtained oxide films have a good adhesion. The duplex treatment has enhanced the hydrophilicity of the TLM alloy, and it would be good for its biocompatibility.
