The erosion of the metal-ceramic particles dispersion composite materials was experimented for the purpose of improving the erosion resistance of the elbow for the transportation line of solid particles. The composite flat plates were made by casting method adding the alumina particles of 3 mm diameter into each matrix. The effects of the impingement particle and the impingement angle on the erosion of the composite were investigated. It was made clear that the erosion ratio of the composite was decreased to a half of the average value of the matrix only. Then, the improvement of the erosion resistance of the trial composite elbow was confirmed.
