摘要
The effects of binder, additive and sintering temperature on the properties ofcalcia as a mold material used for titanium-aluminum alloys have been studied. The results showed that the solution of CaCl2C2H5OH is the best binder for calcia, the additive of CaF2 not only increases the strength but also the anti-watering property of calcia; sintering at 900 similar to 1 000 degrees C is adaptable. The contamination of calcia on titanium aluminum alloy castings has been studied, and the experimental results showed that the thickness of contamination is less than 15 mu m.
