    摘要:

    采用低溫化學(xué)方法在AZ31B鎂合金表面制備出氟涂層，并研究了涂層的表面特征，氟處理后AZ31B鎂合金在模擬體液中的腐蝕行為。結(jié)果表明，氟涂層均勻致密，與基體結(jié)合良好。經(jīng)氟處理后的AZ31B鎂合金的耐蝕性能有較大提高，其在模擬體液中的降解緩慢，合金浸泡后溶液的pH值保持在7.5~8.8之間，有效降低了合金降解而引起的堿性增強(qiáng)趨勢(shì)。氟涂層在模擬體液中會(huì)逐漸轉(zhuǎn)化為Ca3(PO4)2，新生成的表面膜會(huì)繼續(xù)起到保護(hù)合金基體的作用。

    Abstract:

    Fluoride-coating was prepared on AZ31B magnesium alloy by an immersion treatment in hydrofluoric acid at room temperature, and the surface morphology, composition, corrosion resistance and degradation mechanism of the coated alloy were studied. The results show that the conversion coating is compact with good bonding to the alloy. The corrosion resistance of the fluoride coated AZ31B alloy is obviously improved, and its degradation in simulated body fluid (SBF) is slow. The pH value of the SBF (the coated alloy immersed in) keeps in a range of 7.5 to 8.8, which can effectively reduce the alkalization caused by the biodegradation of the alloy. The fluoride coating gradually transform into Ca3(PO4)2 in SBF, which will continue protect the alloy from the corrosion.
