| description | The paper analyzes the morphology of cavitation damage of raw and sintered
basalt samples. The experiment was conducted using the ultrasonic vibratory
cavitation test method according to the ASTM G-32 standard. During the
determination of the resistance to the effect of cavitation, a change in the
mass of samples was observed in the function of the cavitation time of
operation. The morphology of damage caused by the effect of cavitation was
followed by scanning with an electron microscope, and the level of
degradation of the surface of the samples was quantified using the image
analysis. The results showed a significantly higher degree of resistance of
sintered basalt, with a cavitation rate of 0.019 mg/min relative to raw
basalt, with a cavitation rate of 0.738 mg/min. After 120 minutes of
exposure to the cavitation effect, a smaller number of small pits on the
surface of sintered basalt were observed, while a higher level of damage to
the surface with the appearance of numerous pits was found in raw basalt,
which can be connected in some places to larger and deeper pits in some
places. The obtained results indicate the possibility of using sintered
basalt for the production of parts that will be exposed to the effects of
high cavitation loads. [Project of the Serbian Ministry of Education, Science and Technological Development, Grant no. TR 35002 and Grant no. 34006] |
