Abstract
Severe cavitation-erosion has often been experienced at the cooling water side of some diesel engine cylinder liners.
To protect against the erosion various protective methods have been tried.
In this paper, the accelerated Cavitation-erosion tests were made under the addition of various corrosion inhibitors such as emulsified oils, chromates, nitrites, and organic amine-inhibitor into rfesh water, and also the potential of test pieces was measured under cavitation conditions.
Inhibited water could reduce the erosion loss by half to quarter when compared with noninhibited one.
From the results of potential measurement during the cavitation test periods, the inhibitive effect of these inhibitors on cavitation-erosion was considered to be due to the formation of adsorbed films which increased the original cavitation-erosion resistance.
