Abstract
In this paper, the cavitation erosion respectively the dry sliding wear behaviour of the Ysn83 antifriction alloy and EN-GJS-400-15 spheroidal cast iron was studied. As cavitation erosion aspects, the authors show some preview results of the Ysn83 antifriction alloy behaviour and continue to study and to compare also the cavitation erosion behaviour of the EN-GJS-400-15 spheroidal cast iron. In this regard, the cavitation erosion tests were made using a cavitation stand and the experimental results were presented through mass loss and cavitation erosion rate vs time curves. As dry sliding wear aspects, the tests for the two investigated materials were done with a tribometer through the pin-on-disk method where the authors varied the parameters especially the linear speed and the distance. The obtained results were presented as coefficient of friction evolutions and as wear rates. From all the tests, compared with the YSn83 antifriction alloy, the EN-GJS-400-15 spheroidal cast iron showed a superior cavitation erosion and dry sliding wear behaviour.
