研究了钛钌阳极在室温海水介质中缝隙内的电化学行为。结果表明：钛钌阳极在室温海水中工作时，其缝隙内个质会发生严重酸化，缝内电位低于缝外电位，缝外工作电流密度达到10mA／cm2，缝隙内pH值下降到1．5左右，缝内、外电位差达1．0V。钛钌阳极在室温海水介质中工作时不产生缝隙腐蚀。 The electrochemical behavior of Ti ruthenium anodes in the gap of seawater media at room temperature was studied. The results show that the quality of the Ti ruthenium anodes is seriously acidified in the seawater at room temperature. The potential in the seams is lower than that in the seams. The working current density of the seams is 10mA / cm2 and the pH value in the seams is reduced to 1. 5 or so, sewing inside and outside the potential difference of 1.0V. Titanium ruthenium anodes do not produce crevice corrosion when working in room temperature seawater media.
