Figure 1: Principle of the hydro-erosion test

Hydro erosion is the damage of component surfaces by fluid flow. Hydroerosion testing uses a high-pressure water jet to simulate damage caused by liquids. The angle at which the water jet hits the material surface has a significant influence on the damage. At ISAF, a test rig is set up, Figure 1, which allows wear investigations at different angles of impact. In addition to the angle, the jet velocity can be adjusted over a wide range.
