| Popis: | The paper examines the dependence of corrosion rate of nanosized copper films in an HCl aqueous solution on the frequency and strength of an alternating electrical field and ultrasound as well as the thickness of layers under these factors. The corrosion rate was evaluated from increase in the resistivity of films. It is shown that the corrosion rate decreases at least by one-fifth in the range of low strength (to 5 V/cm and 10 dB, respectively) and frequency (to 200 kHz). The corrosion slows down because ions of the solution participate in the oscillation process. This effect of alternating field and ultrasound can be used to control the corrosion rate of nanosized copper films in electronics and medicine. The influence of ultrasound is predominant for layers less than 100 nm in thickness since it decreases the high chemical activity of nanosized film islands. |
