corr）向負(fù)值偏移，腐蝕電流密度（icorr）增加了2個(gè)數(shù)量級(jí)。磨損和腐蝕磨損結(jié)果顯示，Ti-20Zr-10Nb合金的磨損體積隨載荷的增加而增大。研究結(jié)果表明，機(jī)械磨損在腐蝕磨損中對(duì)材料的流失貢獻(xiàn)大于腐蝕的貢獻(xiàn)。電化學(xué)腐蝕條件下的摩擦系數(shù)均低于純磨損條件下獲得的摩擦系數(shù)。通過觀察腐蝕磨損后的形貌可知，磨粒磨損為腐蝕磨損中的主要磨損機(jī)制。此外還驗(yàn)證了磨粒的添加對(duì)磨損和腐蝕磨損行為的影響，發(fā)現(xiàn)磨粒的添加會(huì)增加材料的流失。;The corrosion, wear and tribocorrosion behavior of a new biomedical Ti-20Zr-10Nb alloy was investigated using electrochemical measurements, tribological tests and scanning electron microscopy (SEM). Potentiodynamic polarization tests show that the corrosion potential (Ecorr) shifts towards negative values and that the corrosion current density (icorr) is increased by two orders of magnitude; these trends differ from those observed with static corrosion. The wear and tribocorrosion results indicate that the wear volume of the Ti-20Zr-10Nb alloy increases with increasing applied load. The contribution of mechanical wear to the material loss of tribocorrosion is greater than that of corrosion. However, the friction coefficients obtained under conditions of electrochemical corrosion are lower than that obtained only under wear. Through observation of the wear crack, it is determined that abrasive wear mechanism is the main mechanism of tribocorrosion. The effect of abrasive particles on the wear and tribocorrosion behavior is considered, and it is found that material loss increases due to particle damage."/>
