摘要：
Atomic force microscopy (AFM) is powerful technique to study surface properties and processes in the mu m- and nm-range. In-situ liquid AFM measurements were conducted to evaluate the surface degradation of two biocompatible metals: Ti as the most bio-inert (bio-stable) and Mg as the promising biodegradable metal. The pure Mg and Ti thin films were deposited using DC magnetron sputtering on glass substrates. The corrosion resistances of the samples were evaluated in in pure water and phosphate buffered saline (PBS). The results showed exponential decay of film thickness in water.
