摘要：
SiC/(W,Ti)C laminated ceramic nozzles were produced by hot pressing. The purpose is to induce a compressive residual stress at the entry area of the laminated ceramic nozzles in fabricating process, and leading an improved erosion wear resistance of the laminated ceramic nozzles. The residual stresses arise from a mismatch between the coefficients of thermal expansion of the constituent phases and neighbouring layers. The value of this residual stress was calculated by means of the finite element method. Effect of this kind of residual stress on the erosion wear of the laminated ceramic nozzles was investigated.
