摘要：

In order to investigate the corrosion behaviour of titan in aqueous solutions of lactic acid (1, 3 and 4% w) and albumin (2 and 10 % w) the cyclic polarization curves in potentiodynamic conditions were used. The corrosion parameters were estimated and their values were discussed as a function of acid lactic and albumin concentration and temperature. The stability of titan in investigated biological liquids was interpreted by involvment of the adsorption of either lactic acid or albumin onto the passive layer, a process which is favorised by moderate temperatures (as 37 degrees C-the human body temperature) as well as by low concentrations of lactic acid and albumin, respectively.
