Other AbstractComposites with co-continuous structure of Si3N4/1Cr18Ni9 Ti were prepared via a twostep process, namely gel casting and pressure casting. The phase composition, macro-and micro-structure of the composites were characterized. The erosion rate in flow slurry composed of water and quartz sand, as a function of impingement angle, flow velocity, sand content and erosion time was assessed in comparison with the plain 1Cr18Ni9 Ti. Results show that Si3N4/1Cr18Ni9 Ti composites exhibited a perfect co-continuous phase structure with a good combination between Si3N4 and 1Cr18Ni9Ti;the fluctuation of erosion rate as a function of impingement angle of this composites is smaller than that of 1Cr18Ni9Ti;the erosion rate of composites has an exponent relationship with flow velocity(E∝V0.67), while there is a linear relationship between the erosion rate and flow velocity for 1Cr18Ni9Ti;the erosion rate of this composites decreases gradually with the increasing erosion time and then stabilizes, while that of 1Cr18Ni9 Ti is hardly changed;There is a linear relationship between the erosion rate and sand content in the slurry for the two materials. The composite with co-continuous structure of Si3N4/1Cr18Ni9 Ti exhibits superior erosion resistance, in contrast with the plain 1Cr18Ni9 Ti steel.
