The Fabrication of W/ZrC Composite through Reaction Sintering
مصطفی روستا , حمیدرضا بهاروندی , حسین عبدی‌زاده
Considering the problems and high cost related to graphite parts, the tendency to use composite materials such as W/ZrC as a suitable substitute has been noticed. The important application of these composite materials is in the missile nozzle and aircraft engine parts, fuselage, nose, attack edge, etc. In this study the W-ZrC composites fabricated by in situ reaction sintering of two precursors were compared, 1-The conventional WC and ZrO2 which are ball milled with established molar ratio of 3-1 for 12 hours, gelcasted to form a green body and then undergo a pressure less sintering cycle, 2-A new and innovative way in which for the first time ZrSiO4 was used instead of ZrO2, and by testing different molar ratio between WC and ZrSiO4 it was understood that the optimum ratio is 3-1 once again.
