Abstract
In this short communication, the V–Ns curves (V: impact velocity, Ns: number of specific impacts) for the end of incubation period of erosion were measured using a pulsed-jet erosion tester with an aluminum test specimen (A3003), and the results were compared with those of a whirling-arm tester in the literature. The effects of the jet diameter and liquid film thickness on the wall surface were investigated analytically to compare the V–Ns curves obtained from the pulsed-jet tester with those of the whirling-arm tester. The corrected V–Ns curves of the pulsed-jet tester were found to be consistent with those of the whirling-arm tester within experimental uncertainty when the influences of the droplet diameter and liquid film thickness were considered in the analysis. This result indicates that the pulsed-jet tester provides an effective approach for reproducing V–Ns curves similar to those of the whirling-arm tester.
期刊介绍：
Wear journal is dedicated to the advancement of basic and applied knowledge concerning the nature of wear of materials. Broadly, topics of interest range from development of fundamental understanding of the mechanisms of wear to innovative solutions to practical engineering problems. Authors of experimental studies are expected to comment on the repeatability of the data, and whenever possible, conduct multiple measurements under similar testing conditions. Further, Wear embraces the highest standards of professional ethics, and the detection of matching content, either in written or graphical form, from other publications by the current authors or by others, may result in rejection.
