Effect of Y₂O₃ on Microstructure and Properties of cBN/SiAlON Composite

Abstract:

cBN/SiAlON composites were prepared by spark plasma sintering (SPS) method using Si₃N₄, AlN, Al₂O₃,cBN and Y₂O₃ powders as raw materials. The sintering process is at the temperature of 1500°C holding for 5 min. Effect of the Y₂O₃content on phase composition, microstructure, bulk density, hardness and fracture toughness of the cBN/SiAlON composite was investigated. The experimental results showed that when the Y₂O₃ content was 0.2 wt. % the bulk density and fracture toughness of the composite had the maximum values of 3.0 g/cm³ and K_IC = 5.7 MPa∙m^1/2, respectively. The cBN/SiAlON composite with 0.8 wt. % Y₂O₃ addition got the maximum hardness of 16.4 GPa.
