Abstract

Three kinds of Si₃N₄ based particulate composites were made by adding HfN, ZrN and TiN to Si₃N₄-6w/o Y₂O₃-2w/o Al₂O₃. Variation of sintered density and weight change at temperatures between 1550 C and 2050 C were measured. Mechanical properties were measured on the Si₃N₄ materials with density higher than 97% TD. Fracture toughness was decreased by adding HfN or ZrN to the monolithic Si₃N₄ despite higher thermal expansion coefficients of the particulates added than that of the matrix. TiN particulates improved fracture toughness of the Si₃N₄ material. Flexual strength of the composite was lower than the monolithic Si₃N₄. Friction coefficients were similar to one another. Wear resistance of the Si₃N₄ materials were consistent with the wear model suggested by Evans.
