Erosion by solid particles in the coating of silicon carbide (SiC) substrates of AISI 304 stainless steel was analyzed. The specimens used were 25mm square and 3 mm thick, Silicon Carbide as abrasive particle 300-450 µm size was used. Experimental tests were performed on an apparatus developed in accordance with some parameters of the ASTM standard G76-95. Four angles of impact at 30°, 45°, 60° and 90 ° are contemplated with an approximate particle velocity of 25 ± 2 m / s with a maximum exposure time of 10 minutes per specimen, taking measurements of weight intervals 2 minutes to determine the loss of mass. The wear mechanisms were identified that these small angles were: Plastic deformation, displacement of material, plow mechanisms. While at higher angles they were present mainly: Cuttings, pitting, fractures and microcracks. It was observed that the rate of erosion depends on the angle of incidence of the abrasive particles.
