    摘要:

    研究了新型Ti-19Zr-10Nb-1Fe合金的電化學(xué)腐蝕、磨損和腐蝕磨損行為。電化學(xué)腐蝕測(cè)試結(jié)果表明，在本研究實(shí)驗(yàn)條件下，Ti-19Zr-10Nb-1Fe合金的耐腐蝕性能優(yōu)于Ti-6Al-4V合金。與靜態(tài)電化學(xué)腐蝕相比，由于磨損加速腐蝕，在腐蝕磨損過程中Ti-19Zr-10Nb-1Fe合金的耐腐蝕性能明顯降低。不論是否存在電化學(xué)腐蝕，Ti-19Zr-10Nb-1Fe合金的磨損體積隨著加載載荷的增加而增加。由于電化學(xué)腐蝕的加速作用，Ti-19Zr-10Nb-1Fe合金磨損體積要大于無電化學(xué)腐蝕條件下的磨損體積。Wa/Wc結(jié)果遠(yuǎn)大于10，這說明在腐蝕磨損過程中機(jī)械磨損造成的材料流失遠(yuǎn)大于電化學(xué)腐蝕造成的材料流失。通過SEM觀察Ti-19Zr-10Nb-1Fe合金腐蝕磨損后的磨損形貌可知，在腐蝕磨損過程中磨損占據(jù)主導(dǎo)作用。綜合上述結(jié)果表明，Ti-19Zr-10Nb-1Fe合金在腐蝕磨損過程中，腐蝕加速磨損，磨損加速腐蝕。

    Abstract:

    The electrochemical corrosion, wear, and tribocorrosion behavior of the novel Ti-19Zr-10Nb-1Fe alloy were investigated. The electrochemical corrosion analysis results show that the corrosion resistance of the Ti-19Zr-10Nb-1Fe alloy is better than that of the Ti-6Al-4V alloy under the test conditions in this research. Compared with the static electrochemical corrosion, the corrosion resistance of Ti-19Zr-10Nb-1Fe alloy during tribocorrosion decreases significantly, because the wear accelerates corrosion. The wear volume of Ti-19Zr-10Nb-1Fe alloy is increased with the increase in applied load whether the electrochemical corrosion occurs or not. Due to the acceleration effect of electrochemical corrosion, the wear volume caused by electrochemical corrosion is larger than that without electrochemical corrosion. The results of Wa/Wc are much greater than 10, indicating that during the tribocorrosion process, the material loss caused by mechanical wear is much larger than that caused by electrochemical corrosion. Through SEM observation of the wear morphologies of Ti-19Zr-10Nb-1Fe alloy after tribocorrosion, it can be inferred that the micro-abrasion is the main wear mechanism. The above results show that during the tribocorrosion process, the corrosion accelerates wear, and the wear accelerates corrosion.
