Abstract: For the optimization of an abrasion resistance test method with high speed rotating jet flow, this paper used orthogonal experimental design method to examine the influences of flow velocity, sand content, and abrasion time on test results, and examined the effects of the jet flow angle on test results by varying the radius of the outflow impeller. The optimal abrasion test parameters were determined as follows: flux 2.8L/s, jet velocity 40m/s, sand content 7%, abrasion time 4h, and jet flow angle 34.6°. Tests conducted under this condition exhibited an efficiency about 50 times higher than that of the standard ring method according to DL/T 5150-2001, and the damage pattern of the specimen surfaces was similar to that in-situ.
