Vibroacoustic monitoring of technological processes employing electrophysical phenomena

The rapid development of new technologies employing laser, electron beam, electroerosion and other processes as the working ones requires new approaches to developing systems controlling operations being performed. However, these processes do not lend themselves to visual observation and do not allow the introduction of any sensors into the working process zone, which suggests that vibroacoustic diagnostics methods should be used. The article discusses obtaining information from a vacuum chamber under electron-beam action on thin films of reinforcing coatings. It is shown that the parameters of vibroacoustic signals accompanying the formation of new structures can be recorded with the help of flexible waveguides in the form of a wire drawn from a vacuum chamber to a plate with an accelerometer. The article presents and discusses monitoring the formation of intermetallic compounds under the influence of a pulsed electron beam on an aluminum plate covered with a thin film of a heat-resistant nickel alloy.
