Study of Erosive Surface Characterization of Copper Alloys under Different Test Conditions

In this study, the erosive behavior of copper alloy has been assessed practically at different test conditions using dry compressed air jet test rig under surrounding room temperature. Asymmetrical silica sand (SiO2) is taken into account as erodent particle within the range of 300-600 μm. The impac...
