The effect of morphology and Si content on SiO₂ particle erosion wear of full pearlitic spheroidal graphite cast iron was studied. Experimental data shows the specimens posses more area fraction of cementite for an identical silicon content, that contribute to improve erosion resistance. However, the specimens posses larger interlamellar spacing (λ) at increased Si content, even if the matrix hardness is higher that still debase the erosion resistance. The 2.1Si-air(930°C) specimens not only possess finer λ value and larger cementite fraction but also with better ductility, which could improve erosion resistance.
