According to ASTM G76-95 "Standard Test Method for Conducting Erosion Tests by Solid Particle Impingement Using Gas Jets" specified test method, MaurerLab has developed erosion test machine which can do anti-erosion test to material (small specimens) and simple structure. Through test we evaluate the effect of material erosion rate (gravimetric method) with different sizes (60-180 mesh), different hardness, different angles of incidence (0-90°), different incident rate (maximum 50 m / s).
