Titanium and platinum samples as components of bimetallic implants for the osteoregeneration process have been modified in solutions modeling biological systems and studied by means of cyclic voltammetry, electrochemical impedance spectroscopy and scanning probe microscopy. While aspartic and glutamic acids did not adsorb significantly on platinum in the potential region investigated, the presence of the amino acids affects oxide layer growth on the titanium surface under anodic polarization. The two studied amino acids behave differently on the titanium electrode surface due to differences in adsorption modes of these substances. The adsorption of the glutamic acid depends on the polarization potential to a large extent, and most of quantitative adsorption characteristics (EIS data, the surface roughness) undergo drastic change at the polarization potential value of 750 mV (vs. Ag/AgCl) in the presence of this substance. Equivalent circuit modeling of the surface processes has been carried out, and a scheme for aspartic and glutamic acid adsorption onto the titanium surface has proposed.

钛和铂样品作为用于骨再生过程的双金属植入物的组成部分，已在生物系统的溶液建模中进行了修改，并通过循环伏安法，电化学阻抗谱和扫描探针显微镜进行了研究。尽管天冬氨酸和谷氨酸在所研究的潜在区域中并未明显吸附在铂上，但氨基酸的存在会影响阳极极化下钛表面上的氧化物层生长。由于这些物质的吸附模式不同，这两种研究的氨基酸在钛电极表面的行为也不同。谷氨酸的吸附在很大程度上取决于极化电位，并且大部分是定量的吸附特性（EIS数据，在存在该物质的情况下，极化电位为750 mV（vs。Ag / AgCl）时，表面粗糙度会发生剧烈变化。已经进行了表面过程的等效电路建模，并提出了将天冬氨酸和谷氨酸吸附到钛表面上的方案。
