    Abstract

    Cavitation damage in magnetostriction tests depends primarily on the frequency and amplitude of the oscillation and on the pressure and temperature of the test fluid. The damage is increasing with rising frequency and amplitude; depending upon pressure and temperature it reaches peak values. In water and watery solutions the amount of damage is affected strongly by corrosive influences. In the model setup it is possible to superimpose the influence of corrosion stimulators, corrosion inhibitors, and gases onto specific influences of the device.

    The deterioration of materials by cavitation and corrosion is simultaneously depending on many factors; it is not possible to make generally applicable statements on the significanse of the quality of one single influence. If remedies for a particular damage are to be examined, seperate tests are necessary which have been adapted to this particular purpose.
