Abstract:
ABSTRACT
A systematic investigation has been carried out on cavitation in abrasive suspensions and the impact on surfaces. A mixture of Al2O3 and distilled water is used. It is shown
in this work that the generated surface topography depends strongly on the experimental conditions. Different surface topographies are obtained if only distilled water is
used or if additionally particles are suspended in the fluid. The process is capable of removing burrs with heights of about 20 µm. Another positive result is the reduction
of roughness in micro moulds for micro powder injection moulding during the process. Additional measurements show that by the impact of the particles high compressive
residual stresses can be induced in the near surface layers. The capability of this process will be compared to other finishing processes in the micro regime.
