A shot blasting equipment for determination of material loss due to erosion caused by particle impacts. Abrasive particles are accelerated by air jet. General test parameters are in accordance with ASTM G76-04 standard.
Results obtained with this equipment facilitates determination of erosion wear rate of tested materials under test specific conditions. Importance and meaning of test method in order to characterize the wear behavior of the material depends on many factors related with conditions and test method. Correlation degree between test results using different methods is a user task.
