Dynaflow, Inc. has introduced additions to its specialised materials’ testing capabilities to test the resistance of materials to cavitation and liquid impact with a new test rig which allows for testing of resistance to micro solid particle impact.
The facilities allow the study of properties of the materials undergoing rapid loading and help the engineer to select the most resistant material, or the coating designer to improve the coating.
Dynaflow conducts standard (ASTM G32, G73, G76, G134) tests as well as customised erosion tests for cavitation, liquid droplet, slurry, and solid particle impact, using ultrasonic excitation, high pressure air and water jets, and whirling disk devices.
The various test loops can accommodate a wide range of erosion intensities with water jet pump pressures varying from a very low psi up to 40,000 psi. Dynaflow also conducts split Hopkinson pressure bar tests to measure materials properties at high rates of strain (~5,000/s).
