The results are listed as following :㏕he best anti-erosion proportion of resin present is 25wt% in the condition of silicon carbide reinforced SMCC, while the alumina reinforced SMCC is 40wt%.(2) The better anti-erosion results was achieved with the ratio of silicone resin to acrylic resin containing hydroxy being 3: 1.㏕he composites coating tends to be more brittle when added in alundum particles. It also means that the maximum erosion peak of alundum reinforced SMCC tends to normal angle.甌he change of erosion rate of SMCC can be divided into two stages with the increment erodent velocity: the slow erosion stage of the beginning and the stable erosion stage.
