Water erosion tests on a tantalum sample: A short communication

This paper reports results from an experiment exposing the hot isostatic pressed tantalum cladding of a tungsten spallation target sample to a 34 m/s water jet. The unpolished tantalum surface was placed under the jet for 4.5 months with a view to quantifying pitting and erosion. Micrographs and laser profilometry records of the sample surface taken before and after the experiment are reported here.
