| Abstract [eng] |
The paper is dedicated to synergy of corrosion and mechanical degradation for aluminium alloys. Monitoring of the degradation process was performed using the acoustic emission (AE) method. The authors discuss the possibility of using the AE monitoring system to identify various degradation stages of exposed specimens. There is described the principle of acoustic emission and its practical use possibilities. The problems of the fatigue process and mechanism of crack dispersion on corroded material are solved. The tested samples made from aluminium alloy EN AW 7075 are loaded on a high-cyclic mechanism by four-point bend for fatigue limit testing. With the use of an acoustic emission sensor interconnected with a PC are internal changes in the material monitored. This non-destructive method of material testing is used also for accelerated corrosion monitoring. Using this measurement system it is possible to observe the current status of the machines/devices and to prevent serious accidents. |
